| Is there a way to ssh tunnel, and access a device in the /dev directory, and use it as if it is local? Posted: 14 Jan 2022 11:13 AM PST Is there a way that one computer can share the a device in the /dev/ directory with another computer, and the other computer can interact with it is if it is local? Something analogous to an SSH tunnel? A camera for example, or a serial connection to an arduino, or even the computer's /dev/random? |
| Setting up permanent extra audio sinks/sources for streaming purposes? Posted: 14 Jan 2022 10:25 AM PST So I have been on this for about a month now, and I've tried a dozen different ways of optimizing/automating the process. Basically want to be able to have something setup akin to that of Voicemeeter (windows), but in Linux (arch). My current workaround is the following pactl commands running at startup: { path = "pactl" args = "load-module module-null-sink sink_name=Virtual1" } { path = "pactl" args = "load-module module-null-sink sink_name=Virtual2" } { path = "pactl" args = "load-module module-loopback sink=Virtual1" } { path = "pactl" args = "load-module module-loopback sink=Virtual1" } { path = "pactl" args = "load-module module-loopback sink=Virtual1" }
following which, I manually reroute specific channels in pavucontrol. But every now and then (especially post suspend) the routing is reset to something completely random and I have to go back into pavucontrol and make the necessary changes (specifically in the playback tab). The loading order of the loopback modules are also scrambled at times furthering adding to confusion in the manual tasks I have to perform every time I turn on my system. My requirement is to combine mic and application audio to then send it via the mic (example: discord). Is there any way to keep the sinks and sources not reset them on every boot/newly assign them each time? Or perhaps a way to automate the process of rerouting the channels such that they go exactly where I need them (virtual streams at least)? |
| Which Networks are Relevant from ifconfig? Posted: 14 Jan 2022 10:11 AM PST I was asked to move my question here: I know that a single device may be connected to multiple networks, for example: Wifi, 2 Ethernet Networks etc.... I want to detect all these networks with python by running ipconfig, whose output is something like: But the main problem, how may I know which are relevant and which aren't? For example in my case we have: lo0, gif0, stf0, en6, ap1, en0, awdl0, llw0 etc...
While my laptop is connected only to wifi network. Is there any extra parameter to provide for this command to get only relative results? I would like to know why ifconfig returned all of these even though I'm connected to one network. lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 options=1203<RXCSUM,TXCSUM,TXSTATUS,SW_TIMESTAMP> inet 127.0.0.1 netmask 0xff000000 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 nd6 options=201<PERFORMNUD,DAD> gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280 stf0: flags=0<> mtu 1280 en6: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether ac:de:48:00:11:22 inet6 fe80::aede:48ff:fe00:1122%en6 prefixlen 64 scopeid 0x4 nd6 options=201<PERFORMNUD,DAD> media: autoselect (100baseTX <full-duplex>) status: active ap1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500 options=400<CHANNEL_IO> ether fa:ff:c2:05:aa:71 media: autoselect status: inactive en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM> ether f8:ff:c2:05:aa:71 inet6 fe80::14d9:10f6:b605:46bd%en0 prefixlen 64 secured scopeid 0x6 inet 10.0.0.5 netmask 0xffffff00 broadcast 10.0.0.255 inet6 2a10:8010:d894:0:8de:8a9:ea3a:cd6a prefixlen 64 autoconf secured inet6 2a10:8010:d894:0:19de:c2d8:dd80:95fd prefixlen 64 autoconf temporary nd6 options=201<PERFORMNUD,DAD> media: autoselect status: active awdl0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 options=400<CHANNEL_IO> ether 96:4e:b0:d7:29:0c inet6 fe80::944e:b0ff:fed7:290c%awdl0 prefixlen 64 scopeid 0x7 nd6 options=201<PERFORMNUD,DAD> media: autoselect status: active llw0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 options=400<CHANNEL_IO> ether 96:4e:b0:d7:29:0c inet6 fe80::944e:b0ff:fed7:290c%llw0 prefixlen 64 scopeid 0x8 nd6 options=201<PERFORMNUD,DAD> media: autoselect status: active en3: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 options=460<TSO4,TSO6,CHANNEL_IO> ether 82:43:7a:c3:b8:05 media: autoselect <full-duplex> status: inactive en4: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 options=460<TSO4,TSO6,CHANNEL_IO> ether 82:43:7a:c3:b8:04 media: autoselect <full-duplex> status: inactive en1: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 options=460<TSO4,TSO6,CHANNEL_IO> ether 82:43:7a:c3:b8:01 media: autoselect <full-duplex> status: inactive en2: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 options=460<TSO4,TSO6,CHANNEL_IO> ether 82:43:7a:c3:b8:00 media: autoselect <full-duplex> status: inactive bridge0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 options=63<RXCSUM,TXCSUM,TSO4,TSO6> ether 82:43:7a:c3:b8:01 Configuration: id 0:0:0:0:0:0 priority 0 hellotime 0 fwddelay 0 ifmaxaddr 0 port 10 priority 0 path cost 0 nd6 options=201<PERFORMNUD,DAD> media: <unknown type> status: inactive utun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1380 inet6 fe80::446c:1de1:7516:5c37%utun0 prefixlen 64 scopeid 0xe nd6 options=201<PERFORMNUD,DAD> utun1: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 2000 inet6 fe80::e9e7:de94:f2b:9726%utun1 prefixlen 64 scopeid 0xf nd6 options=201<PERFORMNUD,DAD>

I tried with -L and -o options as well. Is this some sort of a bug or what can be the issue? |

For the first one output, I'm used this following sed command which works: var_type_fic=`cat fic1.txt |sed -r 's/.*charset=([^ ]+).*/\1/'|sort` for fic in $var_type_fic; do echo "$fic" done
But for the second, I can't find the regex match that is going well. Can someone help please? |

| Cant access windows 10 after dual boot with debian 11 Posted: 14 Jan 2022 09:15 AM PST I have just installed a Debian 11 in dual boot with a pre installed windows 10 in a dell notebook. To make the dual boot and access Debian, i had to access the UEFI and: 1 - Alter the boot order so that it privileges the debian partition; 2 - Disable the secure boot option; 3 - Alter the SATA settings from SATA to AHCI; So now the debian works just fine with the GRUB interface and all. However, if i try to access windows via GRUB interface, it just reinitializes the computer. So to actually access windows i need to enter the UEFI again and revert all changes. But then Debian will be unavailable, so if i want to access debian i need to access the UEFI again and revert changes again and so and so... Also, sometimes when i access windows it states that it hasnt been initialized correcltly and needs to enter repair mode or try again. Is there a way i can just have my old pal GRUB working normally and initializing both debian and windows again? |

| Why does supervisor does not log the output of a child process? Posted: 14 Jan 2022 08:45 AM PST When I run the script server.sh (runs a quake dedicated server) in the terminal it will create initialization output like ------- Game Initialization ------- gamename: baseqz gamedate: May 25 2016 initializing access list... loaded 0 steam ids into the access list Not logging to disk. 0 teams with 0 entities 21 items registered
And when some person connects to the server then this script will output something like Person xyz has connected I want supervisor to manage this server.sh script but supervisor does not output any kind of initialization messages or connecting message (if someone connects). Stdout and stderr are both logged. Why does supervisor not log the output of server.sh? Here is my supervisord.conf [program:prog] command=/home/user/.steam/steamapps/common/qlds/server.sh stdout_logfile=stdout.txt stderr_logfile=stdout.txt [supervisord] nodaemon=true [supervisorctl] serverurl=http://127.0.0.1:9001 [inet_http_server] port=127.0.0.1:9001 [rpcinterface:supervisor] supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
EDIT: I noticed a strange behaviour of server.sh server.sh &> out.txt
generates no output in out.txt (no Game initialization, nothink). But only after i typed in stdin "quit" (server.sh quits now) then the Game initialization and so on got written into file out.txt |
| How to assign value using echo to a variable but don't display it in terminal [duplicate] Posted: 14 Jan 2022 08:47 AM PST My bash script #!/bin/bash read -r -p "Enter the filenames: " -a arr for i in "${arr[@]}" do echo $i | sed 's/\(.*\)\..*/\1/' cp -v ~/Desktop/library/template.py "$i".py done
If i write A B.py C D.py, this script will turn it into A.py B.py C.py D.py
-v flag of cp -v explains what is being done but i don't want to print the edited filenames echo $i. It's annoying.
How can i do that?

| How do I add a line of text to the middle of a file using awk? Posted: 14 Jan 2022 08:43 AM PST This is an great answer. https://stackoverflow.com/a/6739327/15603477 But Still a little bit confused me. without a variable, awk '/^nameserver/ { printf("nameserver 127.0.0.1\n")} {print}' file2 will get: # Generated by NetworkManager domain dhcp.example.com search dhcp.example.com nameserver 127.0.0.1 nameserver 10.0.0.1 nameserver 127.0.0.1 nameserver 10.0.0.2 nameserver 127.0.0.1 nameserver 10.0.0.3
After try serval combination, I found out that I had to use awk '/^nameserver/ && !a { printf("nameserver 127.0.0.1\n"); a=1 } {print}' file2 But I am still confused with !a and a=1 function to stop the printf("nameserver 127.0.0.1\n") duplication. |
| Ranger file manager as the singleton instance on shell startup Posted: 14 Jan 2022 11:06 AM PST Problem:
I use zsh and added to its config file a line of launching ranger on startup. .zshrc # A few other settings and commands. ZSH_TMUX_AUTOSTART="true" plugins=(tmux ...) source ranger
Due to it every newly opened(mostly in tmux) zsh runs ranger. Expectation:
Lauch a ranger process only if there is no running one. Something like looks as follow: if [[ ! -v RANGER_RUNNIG ]]; then export RANGER_RUNNING="true" source ranger fi

| Using awk to add a value to a second column and save it as a third column Posted: 14 Jan 2022 09:13 AM PST I have a BED file: MtrunA17CP,0,977,gene:MtrunA17CPg0492171,.,+,EuGene,gene,.,ID=gene:MtrunA17CPg0492171;Name=MtrunA17CPg0492171;locus_tag=MtrunA17_CPg0492171; MtrunA17CP,2410,3570,gene:MtrunA17CPg049219,.,+,EuGene,gene,.,ID=gene:MtrunA17CPg0492191;Name=MtrunA17CPg0492191;locus_tag=MtrunA17_CPg0492191; MtrunA17CP,3571,3697,gene:MtrunA17CPg0492211,.,+,EuGene,gene,.,ID=gene:MtrunA17CPg0492211;Name=MtrunA17CPg0492211;locus_tag=MtrunA17_CPg0492211;
How do I add 250 to a second column and replace the third column with this new value using awk? Also is there a way to take into account strandedness (+ or - DNA strands) since adding to a + strand is going downstream - left to right; and adding to a - strand is moving upstream - right to left? CLARIFICATION: Nothing wrong with $2+=250 and $3=$2, I'm a newb. I was thrown into this (long story) but only have the biological training. So now I am trying to speak the language without first understanding it. Regarding strandedness, I got to ponder on it, but what it is essentially: One DNA strand runs in 5' to 3' direction (positions of nucleotides attached at carbon atoms in the sugar rings). This one is labeled with a "+" sign. The other that runs in the other direction is a copy of the "+" strand and is labeled as a "-" The two strands form a double helix. When counting the nucleotides (coding for our genetic info) they are counted in the "5-3" direction for the "+' strand and "3-5" for the "-" strand. Sorry for the complicated question, I could have only posed it as: How do I add 250 to the second column so that the result is represented in the third column? The third column is already populated with some previous values, so obviously I want those values gone. Column delimiter is a comma. Thank you, hopefully I was clear enough |
| xmodmap resets when keyboard mode changes Posted: 14 Jan 2022 08:10 AM PST I have a Keychron K2 mechanical keyboard and the keys on the righthand side of the keyboard look like this: 
I would like to swap them to a more standard layout, so that, from top to bottom, I would have Light Toggle, Home, Page Up, Page Down, and End. I used xev to retrieve the key codes and wrote a small script that uses xmodmap to swap them to my liking: #!/bin/bash xmodmap -e "keycode 110 = Next" && xmodmap -e "keycode 112 = Home" && xmodmap -e "keycode 117 = Prior"
This script is executed on start up and works exactly as expected. The problem is this keyboard is both wired and Bluetooth. When I switch between wired mode to Bluetooth mode or vice-versa, the keys go back to their default position and I need to manually run my script above one more time. xev shows to me that in both cases the key codes are the same. Is there a better way of tackling this so that these keys are swapped regardless of the keyboard mode I use? |

| How can I fix bluetooth issues which are affecting booting time? Posted: 14 Jan 2022 09:45 AM PST I've recently installed xubuntu 17.10. I noticed some error messages while booting. Here's the my dmesg output(only errors and their previous lines): ... [ 13.717201] usb 5-3: USB disconnect, device number 2 [ 15.164286] Bluetooth: hci0 command 0xfc20 tx timeout ...

| Systemd Restart=always is not honored Posted: 14 Jan 2022 08:59 AM PST Note: I wrote an article on Medium that explains how to create a service, and how to avoid this particular issue: Creating a Linux service with systemd. Original question:
I'm using systemd to keep a worker script working at all times: [Unit] Description=My worker After=mysqld.service [Service] Type=simple Restart=always ExecStart=/path/to/script [Install] WantedBy=multi-user.target
Although the restart works fine if the script exits normally after a few minutes, I've noticed that if it repeatedly fails to execute on startup, systemd will just give up trying to start it: Jun 14 11:10:31 localhost systemd[1]: test.service: Main process exited, code=exited, status=1/FAILURE Jun 14 11:10:31 localhost systemd[1]: test.service: Unit entered failed state.

Jun 14 11:10:31 localhost systemd[1]: test.service: Unit entered failed state. Jun 14 11:10:31 localhost systemd[1]: test.service: Failed with result 'start-limit'.
Similarly, if my worker script fails several times with an exit status of 255, systemd gives up trying to restart it: Jun 14 11:25:51 localhost systemd[1]: test.service: Failed with result 'exit-code'. Jun 14 11:25:51 localhost systemd[1]: test.service: Service hold-off time over, scheduling restart. Jun 14 11:25:51 localhost systemd[1]: test.service: Start request repeated too quickly.

Is there a way to force systemd to always retry after a few seconds? |
| Proxify dns queries at the command-line Posted: 14 Jan 2022 09:17 AM PST I want to use different dns server (not tor, any dns server I set) for certain terminal command. Say it would looks like $ DNS_SERVER=8.8.8.8 dnsify ping example.com
and it uses Google dns. I know there's socksify, torrify and other tools like that. I look for any tool, hack, or other way I can set it explicitly for my command or at least restricted to terminal session. So I use different dns for my command or in my terminal session, and main dns for all other software. I tryed proxychains but can't force it to use non-system proxy. So, is there anything for dns proxifying? |
| Segmentation Fault when trying to mount ext(2,3,4) fs, from usb (openwrt) Posted: 14 Jan 2022 08:04 AM PST So I have a TL-MR3220v2 router, which has Openwrt installed, this device only has a 4mb flash so I'm trying to get extroot setup on a USB, to increase disk space. My first attempt I tried using a FAT32 FS, which I was able to get mounted and transfer files, but I quickly realized that this FS would not work as a linux root because of permissions, symlinks, and such. So I tried again this time with a ext4 formatted usb. So I then try to mount this partition onto my device, but every time it results in a 'segmentation fault' with the following in my dmesg log: [ 1146.920000] usb 1-1: new high-speed USB device number 3 using ehci-platform [ 1147.070000] usb-storage 1-1:1.0: USB Mass Storage device detected [ 1147.090000] scsi host1: usb-storage 1-1:1.0 [ 1148.390000] scsi 1:0:0:0: Direct-Access Lexar USB Flash Drive 1100 PQ: 0 ANSI: 4 [ 1148.400000] sd 1:0:0:0: [sda] 31258624 512-byte logical blocks: (16.0 GB/14.9 GiB) [ 1148.410000] sd 1:0:0:0: [sda] Write Protect is off [ 1148.420000] sd 1:0:0:0: [sda] Mode Sense: 43 00 00 00 [ 1148.420000] sd 1:0:0:0: [sda] No Caching mode page found [ 1148.430000] sd 1:0:0:0: [sda] Assuming drive cache: write through [ 1148.440000] sda: sda1 [ 1148.450000] sd 1:0:0:0: [sda] Attached SCSI removable disk [ 1168.550000] CPU 0 Unable to handle kernel paging request at virtual address c0676c40, epc == c0676c40, ra == c0694dd0 [ 1168.560000] Oops[#4]: [ 1168.560000] CPU: 0 PID: 1596 Comm: mount Tainted: G D 3.18.18 #1 [ 1168.560000] task: 8182a220 ti: 8155a000 task.ti: 8155a000 [ 1168.560000] $ 0 : 00000000 00000000 c0698e60 00000000 [ 1168.560000] $ 4 : c06c6b30 00008000 81578700 00000000 [ 1168.560000] $ 8 : 00003100 8157868a 00000010 00000013 [ 1168.560000] $12 : 7fb3d928 00000000 00000000 770b4000 [ 1168.560000] $16 : 80f6c780 81578700 c06c6b30 c06c6b30 [ 1168.560000] $20 : 00000000 00000000 81578c00 770b4000 [ 1168.560000] $24 : 00000010 8016c38c [ 1168.560000] $28 : 8155a000 8155be38 00000000 c0694dd0 [ 1168.560000] Hi : 00000019 [ 1168.560000] Lo : 00000000 [ 1168.560000] epc : c0676c40 0xc0676c40 [ 1168.560000] Tainted: G D [ 1168.560000] ra : c0694dd0 ext4_orphan_del+0x108c/0x1f30 [ext4] [ 1168.560000] Status: 1000fc03 KERNEL EXL IE [ 1168.560000] Cause : 10800008 [ 1168.560000] BadVA : c0676c40 [ 1168.560000] PrId : 00019374 (MIPS 24Kc) [ 1168.560000] Modules linked in: ext4 jbd2 mbcache crc16 crypto_hash usb_storage sd_mod scsi_mod ath9k ath9k_common pppoe ppp_async iptable_nat ath9k_hw ath pppox ppp_generic nf_nat_ipv4 nf_conntrack_ipv6 nf_conntrack_ipv4 mac80211 ipt_REJECT ipt_MASQUERADE cfg80211 xt_time xt_tcpudp xt_state xt_nat xt_multiport xt_mark xt_mac xt_limit xt_id xt_conntrack xt_comment xt_TCPMSS xt_REDIRECT xt_LOG xt_CT slhc nf_reject_ipv4 nf_nat_masquerade_ipv4 nf_nat_ftp nf_nat nf_log_ipv4 nf_defrag_ipv6 nf_defrag_ipv4 nf_conntrack_rtcache nf_conntrack_ftp nf_conntrack iptable_raw iptable_mangle iptable_filter ip_tables crc_ccitt compat ledtrig_usbdev ip6t_REJECT nf_reject_ipv6 nf_log_ipv6 nf_log_common ip6table_raw ip6table_mangle ip6table_filter ip6_tables x_tables ipv6 arc4 crypto_blkcipher ohci_platform ohci_hcd ehci_platform ehci_hcd gpio_button_hotplug usbcore nls_base usb_common [ 1168.560000] Process mount (pid: 1596, threadinfo=8155a000, task=8182a220, tls=770c1644) [ 1168.560000] Stack : 80400000 80f6c780 81578700 804073f0 c0698e60 80116f30 81733300 800ffc68 [ 1168.560000] 00000000 81578c00 c06c6b30 81578700 00008000 c06c6b30 80f6c780 81578700 [ 1168.560000] 00008000 80116fdc 00008000 8010a4a0 00000001 7fb3df74 c06c6b30 00000020 [ 1168.560000] 80391f70 00008000 81578700 80119de8 8182ebc0 7fb3df74 0000000a 800ddc68 [ 1168.560000] 81b1f010 8088e4c8 7fb3dc34 770b4000 00000000 0000000a 00000000 81578c00 [ 1168.560000] ...

If not sure what going on here, I dont think RAM is a problem as the free command show that half my ram is still unused, and i did try with ext2 and 3 but i just get the same output. So if anyone has any idea i would greatly appreciate it! Thanks! EDIT: So I found this page http://blog.csdn.net/u011839461/article/details/12001437 which say if BadVA == epc then it is most likely memory corruption, but Im not sure what i can do about it. |
| Increase Icon/Text Size in Kali Linux Posted: 14 Jan 2022 08:13 AM PST I am running Kali Linux in a virtual box (VMWare Player), and although the resolution fits my screen properly, the icons, windows, text is so small. In example, when I use the terminal or browse using Iceweasel, the windows they appear in show small text, and everything is not proportioned properly to size. It seems that everything has shrunk in size; even the dropdown menus on the desktop, and windows that open are not properly displayed regarding size. How can I increase the size so that windows, text, desktop icons and desktop menus display properly (standard size)? |
| Unable to use python speech_recognition lib Microphone class due to ALSA Posted: 14 Jan 2022 09:07 AM PST I am attempting to write a speech recognition program for the raspberry pi, however I am facing some issues using python's speech_recognition library. From the error messages (posted below) I think the issue may be with the wrong sound card being accessed, however I am able to record with PyAudio (which I think the microphone class uses) as well as 'arecord' Below is the code I am trying to run: import speech_recognition as sr r = sr.Recognizer() with sr.Microphone() as source: while True: audio = r.listen(source) try: printf("You said " + r.recognize(audio)) except LookupError: printf("Could not understand audio")
I have made some adjustments to which soundcard is used as default. My "/etc/modprobe.d/alsa-base.conf" file is untouched and standard. I have created a file in /home/pi under the name ".asoundrc" which contains: pcm.!default { type asym playback.pcm "hw:0,0" capture.pcm "hw:1,0" }
This allows for recording from the USB microphone and playback through the on-board headphone jack port. Below is the error message I received when trying to run the python script: pi@raspberrypi ~/Desktop $ python speechtester.py ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'cards.bcm2835.pcm.front.0:CARD=0' ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4720:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM front ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'cards.bcm2835.pcm.surround40.0:CARD=0' ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4720:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM surround40 ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'cards.bcm2835.pcm.surround51.0:CARD=0' ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4720:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM surround41 ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'cards.bcm2835.pcm.surround51.0:CARD=0' ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4720:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM surround50 ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'cards.bcm2835.pcm.surround51.0:CARD=0' ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4720:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM surround51 ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'cards.bcm2835.pcm.surround71.0:CARD=0' ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4720:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM surround71 ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'cards.bcm2835.pcm.iec958.0:CARD=0,AES0=4,AES1=130,AES2=0,AES3=2' ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4720:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM iec958 ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'cards.bcm2835.pcm.iec958.0:CARD=0,AES0=4,AES1=130,AES2=0,AES3=2' ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4720:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM spdif ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'cards.bcm2835.pcm.iec958.0:CARD=0,AES0=4,AES1=130,AES2=0,AES3=2' ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4720:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM spdif ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.hdmi ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.hdmi ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.modem ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.modem ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.phoneline ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.phoneline ALSA lib pcm_dmix.c:957:(snd_pcm_dmix_open) The dmix plugin supports only playback stream Cannot connect to server socket err = No such file or directory Cannot connect to server request channel jack server is not running or cannot be started

| Force apt-get to prompt yes/no Posted: 14 Jan 2022 10:07 AM PST Is there a way to force apt-get to display yes/no prompt? A --force-yes option exists, but there seems to be no --force-prompt or similar option. If you attempt to install a package that has all dependencies already installed, it will begin installation without displaying a yes/no prompt. This can be bothersome if you want to review whether dependencies exist and which ones will be installed because you don't know if the potential dependencies are installed ahead of time. NOTE: When does "apt-get install" ask me to confirm whether I want to continue or not? is somewhat related in that it describes under what standard conditions the prompt is displayed. I'm interested to know how to force it though. |
