| Every linux distrib freezed "to death" Posted: 31 May 2022 12:44 PM PDT Trying to install linux on my home pc, already tried: PopOS, Ubuntu, Debian, Arch, Manjaro. Every distrib just freezes without any response after ~1-15minutes. Somehow managed to install debian with gnome and get some logs.
Asking for help here, because i've run out of options, after searching everything that i can google, managed to get debian work for 10 minutes with X.M.P profile on(it was disabled by default).
My specs:
- Gigabyte B450M Gaming X
- Ryzen 5 3500x
- Nvidia Geforce 1650
- 2x8GB DDR4 2666GHz AMD ram
Trying to install on Silicon Power 128GB SSD
Here's some logs that i got in debian before freeze:

| fish shell: why does `file `which command`` work in zsh and bash, but not fish? Posted: 31 May 2022 12:32 PM PDT Before switching to fish shell, I frequently used various commands in zsh with which some_command. An example might be: $ file `which zsh` /opt/local/bin/zsh: Mach-O 64-bit executable arm64 /bin/zsh: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64 - Mach-O 64-bit executable x86_64] [arm64e:Mach-O 64-bit executable arm64e - Mach-O 64-bit executable arm64e] /bin/zsh (for architecture x86_64): Mach-O 64-bit executable x86_64 /bin/zsh (for architecture arm64e): Mach-O 64-bit executable arm64e
When I try to do this with fish it fails: $ which zsh /opt/local/bin/zsh $ file `which zsh` `which: cannot open ``which' (No such file or directory) zsh`: cannot open `zsh`' (No such file or directory)
Any idea of why this doesn't work fish as opposed to other more bash-like shells? |
| Is it possible to search through a .tar.gz file breadth-first? Posted: 31 May 2022 01:04 PM PDT I want to download part of a large (199GB) .tar.gz from here. To start, I used the following command to list all of the files in the .tar.gz file: wget -qO- https://www.cs.cornell.edu/projects/megadepth/dataset/Megadepth_v1/MegaDepth_v1.tar.gz | tar -tz
Next, I tried to download the contents of a folder in the .tar.gz using the command: wget -qO- https://www.cs.cornell.edu/projects/megadepth/dataset/Megadepth_v1/MegaDepth_v1.tar.gz | tar -xz phoenix/S6/zl548/MegaDepth_v1/0000
However, this takes too long because the tar command searches depth-first and recursively through each of the folders below phoenix/S6/zl548/MegaDepth_v1. I am only interested in the contents of the folder phoenix/S6/zl548/MegaDepth_v1/0000. Is there a way to download the contents of this folder without searching through the sub-folders of the other folders, such as phoenix/S6/zl548/MegaDepth_v1/0162 phoenix/S6/zl548/MegaDepth_v1/0001 phoenix/S6/zl548/MegaDepth_v1/0132
In other words, is there a faster way to download the contents of the folder phoenix/S6/zl548/MegaDepth_v1/0000?

| stable, mainline linux kernel Posted: 31 May 2022 12:35 PM PDT My question is about understanding mainline, stable kernel versions. Let us take the example of a 5.18 mainline. My understanding is that 5.18 is the mainline and 5.18.1 is the stable kernel. For production companies use 5.18 or 5.18.1? From the kernel.org; Stable After each mainline kernel is released, it is considered "stable." Any bug fixes for a stable kernel are backported from the mainline tree and applied by a designated stable kernel maintainer. There are usually only a few bugfix kernel releases until next mainline kernel becomes available -- unless it is designated a "longterm maintenance kernel." Stable kernel updates are released on as-needed basis, usually once a week.
What does this mean, this mean 5.18.1 bug fix release will be back ported to 5.18? |

| Why is the linux system call interface architecture-dependent? Posted: 31 May 2022 11:50 AM PDT So one thing I'm not clear on is why transitioning from user space to kernel space is architecture-dependent. For example, the linux kernel v5.4 code for system calls entering kernel space is different for x86 vs different architectures, and contains architecture-dependent assembly instructions, rather than just C code. Why is this exactly? Why can't the entire linux kernel just be written in C...? Any thoughts appreciated. Thanks. |
| Is it POSIX compliant for find -exec /no/such/file {} \; to exit with an error? Posted: 31 May 2022 10:16 AM PDT I am the author of a find replacement which attempts to be compatible with POSIX (and with many popular extensions). Recently I noticed a discrepancy between the behaviour of my utility and other find implementations, and I want to know if POSIX allows my behaviour or if I need to change it. $ find . -exec /no/such/file {} \; find: '/no/such/file': No such file or directory $ echo $? 0 $ bfs . -exec /no/such/file {} \; bfs: error: .: -exec /no/such/file: No such file or directory. $ echo $? 1
At least GNU, busybox, and FreeBSD find all have exit status 0 in this case. My implementation propagates the execv() error from the fork()ed child to the parent, while the other implementations seem to print the error directly from the child without telling the parent. The reason I ask this question, rather than just change the behaviour to match the others, is that it seems difficult to do when using posix_spawn(). Implementations of posix_spawn() are allowed to propagate execv() errors to errno in the parent, and e.g. glibc and musl both do this. It seems impossible to tell whether the error occurred before or after the fork(), and presumably errors from before the fork() (e.g. ENOMEM) should lead to a non-zero exit status. I have read the POSIX specification for find, but it's light on details here. However, I've heard that there are other rules documented elsewhere that might be relevant. For example, I've heard that if a utility prints to standard error, it must also exit with a nonzero exit code, which seems to imply that the other finds are not compliant. But I'm not sure where that wording is, or if it really exists. |
| Granting users access to mounted cifs share Posted: 31 May 2022 12:14 PM PDT I'm mounting a Windows file share to my ubuntu machine and trying to give all users permission to read and write files.
The file share contains only one file at this point. I am able to mount the drive, but when attempting to cat read the file I get error: cat: myfile.txt: Permission denied
Creating the local folder:
sudo mkdir -m777 /mnt/MyShare
Mounting the drive:
sudo mount -t cifs -o username=domainUser,domain=domain.com,file_mode=0755,dir_mode=0755 "//MyWindowsServer/directory/My Subdirectory" /mnt/MyShare --verbose Password for domainUser@//MyWindowsServer/directory/My Subdirectory: **********
After that I'm able to cd to MyShare and see the existing file: cd /mnt/MyShare
ls
myfile.txt
However, when I try to cat read that file, I get "permission denied".
How can I resolve this? |

| Linux packet mark across network namespaces Posted: 31 May 2022 12:14 PM PDT I am trying to use iptables to packet mark packets of a certain source/destination IP in the mangle table on a given host. The packets are later forwarded to a particular network namespace on the same host, yet the iptables rules that I've installed in that network namespace do not pick up on the mark. I am thus wondering: is packet marking only local to the network namespace the mark is being placed in? I was under the impression that since the mark is an "attribute" associated with the skb, that the kernel would keep track of the mark anywhere it's routed on the host, irrespective of the namespace. Alternatively does anyone have any ideas of how to debug this? I installed a TRACE rule inside the network namespace I am targeting, but I am under the impression that I need to run dmesg to view the output and that doesn't make a lot of sense for a network namespace. |
| Is it possible to use options -i and -E simultaneously in sed? Posted: 31 May 2022 11:23 AM PDT I have a file like public class Constants { public static final String PACKAGE_VERSION = '1.24.0.1'; }

I receive an error sed: 1: "force-app/main/default/ ...": invalid command code f
I want the script to work both in MacOS and Linux without changing the script. I tried to use awk, but I don't understand how can I make it inline editing the file?

| Is this drive dead? Posted: 31 May 2022 10:32 AM PDT Frankly I don't know what to title this issue/question... I have this one particular drive in my basic home server that is causing me headaches. Just finished restructuring my media library (sorting and renaming photos, deleting duplicates, ...). It was a lot of work and now, the drive I restructured to, is failing/acting up. It's a Seagate Barracuda ST31000528AS, 1TB, 7200rpm from 2009(-ish) with only one ext4 partition. The drive is still readable and writable, but at a very slow speed (see below). Can you help me figure out if this a hardware failure or some problem with the filesystem? I will definitly replace this drive in the future, as I have lost confidence in it... But the data on it is still important to me. So do I spend 21 days that it would take to copy the data off of it, or do the wizards of this forum have the power to get this drive back into working order? EDIT Just remembered it, might also be the motherboard, as it is similarly old. I will try a different SATA port now... EDIT 2 As per the previous edit, I switched to another SATA port on the Mainboard and this actually fixed everything. No errors in the logs, no IO Errors, 100s of MB/s of throughput. The drive is healthy, the Mainboard is not! Symptoms: badblocks is returning nothing for the first 233k blocks (0.1% of all blocks, which took over an hour)- the

| Relationship between framebuffer and a tty Posted: 31 May 2022 09:49 AM PDT A framebuffer is a device file which allows for a simplified interface to the screen. For example running the below code on a RaspberryPi with a HDMI display connected: cat /dev/urandom > /dev/fb1
There are commands (fbi, fim) which allow for injecting full images into the framebuffer. There are multiple resources on the internet (ref1, ref2, ref3) trying to more or less succesfully explain how to add make a systemd service which will result in an image on the screen. A common thread in those resources is the mentioning tty together with the framebuffer. (i.e. both fbi and fim have options to pass them a tty).
My assumption was that a tty is a separated concept from a framebuffer. The tty uses the framebuffer to output content to a user, but the framebuffer isn't in any way tied to a tty. Is there a hidden relationship behind a tty and a framebuffer which could explain why commands to print images to a framebuffer seem to depend on a tty? |

| Grep subfolder files and display the matched file name Posted: 31 May 2022 12:56 PM PDT I have one unique requirement. Inside a folder there is plenty of subfolder and inside the subfolder there is plenty of CSV file. Looks like below SubfolderWB >File1.csv >File2.csv SubfolderMUM >File3.csv >File4.csv >file5.csv SubfolderKEL >File6.csv >File7.csv
Now in each subfolder I need to pick the last file(or latest file created) and match with keyword using grep. If the keyword matches I need the file name. Example: I need to find foo in CSV files in all subfolders.
So I need to pick files cat SubfolderWB/File2.csv,SubfolderMUM/file5.csv ,SubfolderKEL/File7.csv | grep foo.
If foo is present in file5.csv it should give me final output as file5.csv. |
| Rsync command not copying files from /snap dir Posted: 31 May 2022 10:19 AM PDT I made an rsync backup of my Ubuntu 22.04 OS as it was running in a Raspberry Pi. The backup is made to an image file partitioned and formatted the same as the SD Card. Later I mount the backup image file and also take out the SD Card and mount it as well. Root partition on backup image mounted at /media/writable
Root partition on SD Card mounted at /media/writable1 When I do a directory listing of files I can see that some are in there but NOT in the source SD Card. [flex@flex-inspiron7520 ~]$ ls -l /media/writable/snap/core20/1437/etc/default total 28 -rw-r--r-- 1 root root 460 Feb 4 2020 cryptdisks -rw-r--r-- 1 root root 297 Sep 30 2019 dbus -rw-r--r-- 1 root root 15 Mar 29 20:47 locale -rw-r--r-- 1 root root 1756 Apr 14 2020 nss -rw-r--r-- 1 root root 133 Dec 2 22:38 ssh -rw-r--r-- 1 root root 35 Mar 29 20:47 swapfile -rw-r--r-- 1 root root 1118 Feb 7 2020 useradd [flex@flex-inspiron7520 ~]$ ls -l /media/writable1/snap/core20/1437/etc/default ls: cannot access '/media/writable1/snap/core20/1437/etc/default': No such file or directory
I do a dry run of the rsync command and it tells me that it will copy files from the source (backup image) that are missing in the destination (sd card). [flex@flex-inspiron7520 ~]$ sudo rsync -nrlpgoDv /media/writable/snap/core20/1437/etc/default /media/writable1/ sending incremental file list default/ default/cryptdisks default/dbus default/locale default/nss default/ssh default/swapfile default/useradd sent 205 bytes received 41 bytes 492.00 bytes/sec total size is 3,814 speedup is 15.50 (DRY RUN)
By the way the reason the files are missing in the destination SD Card compared with the backup OF THAT card is because the files were there when the sd card was attached to the Pi and the OS was running... they are the snap applications that are mounted in /snap only when the OS is running. But that's not my question! My Question When I run this rsync command it gives me output about what files it plans on copying from the source (backup image) to the destination (sd card) sudo rsync -nrlpgoDv /media/writable /media/writable1/
There are alot of files to transfer, this is just the first few lines... writable/var/lib/dpkg/info/python3.10-minimal.list writable/var/lib/dpkg/info/python3.10-minimal.md5sums writable/var/lib/dpkg/info/python3.10-minimal.postinst writable/var/lib/dpkg/info/python3.10-minimal.postrm writable/var/lib/dpkg/info/python3.10-minimal.preinst writable/var/lib/dpkg/info/python3.10-minimal.prerm writable/var/lib/dpkg/info/python3.10.list writable/var/lib/dpkg/info/python3.10.md5sums . .. .... .....
However... there are no writable/snap/... lines in the output? Why does this rsync command not list out the same files as above that ARE in /media/writable/snap/core20/1437/etc/default but NOT in /media/writable1/snap/core20/1437/etc/default. Apparently the '/snap' directory is a set of mount points for loop devices referencing the snap applications located in '/var/lib/snapd/'. I'm not sure if that is related? Update Is it because of how the two file systems are mounted maybe? The backup image is mounted readonly but the SD Card is mounted as readwrite? But my rsync command tries to copy from the backup image so probably not related? [flex@flex 1437]$ mount | grep writable /dev/loop0p2 on /media/writable type ext4 (ro,nosuid,nodev,relatime,errors=remount-ro,uhelper=udisks2) /dev/sdb2 on /media/writable1 type ext4 (rw,nosuid,nodev,relatime,errors=remount-ro,uhelper=udisks2)
Any help much appreciated, Flex |

| Invalid MIT-MAGIC-COOKIE-1 when I run mpirun Posted: 31 May 2022 12:03 PM PDT Suddenly whenever I run mpirun I get the error Invalid MIT-MAGIC-COOKIE-1 key. I think this might have started after I killed a command using mpirun that had been launched from a python console. I looked at $XAUTHORITY and found no .Xauthority file. I also tried xhost +local: in the terminal but the problem remains. I have only used mpirun to run things locally on my pc. (For the most part mpirun does seem to do what it is supposed to, but I believe it also now creates errors in things that were working perfectly before.) Simply running the below shows the warning for example (nonsense minimal example): /usr/bin/mpirun -n 1 echo "bla"
I ran export XAUTHORITY="$XDG_RUNTIME_DIR"/Xauthority
because it solved the issue for someone else but it seemed to have made things worse (?). Now it says No protocol specified
whenever I run mpirun. By going through the steps in https://superuser.com/a/941244/728074 it goes back to saying Invalid MIT-MAGIC-COOKIE-1 key. Also my $DISPLAY was set to nothing it seems. I tried setting it to ":1" or ":0" but that does not resolve the issue. I also do not know whether it had a value before but some posts suggest its value is relevant for this error.

| How does Linux CFS schedule processes vs threads fairly in 2018 4.9 kernels? Posted: 31 May 2022 12:13 PM PDT The Linux scheduler keeps evolving: How does the kernel schedule processes vs threads today? Do I need autogroups? The previous similiar stack overflow question is many years old and likely obsolete. I believe in 2018 the default is the Completely Fair Scheduler (CFS) instead of O(1) or other scheduler. For Linux, some documentation mentions the OS juggles tasks which indifferently represent a process or a thread of a process, or does not clearly make the distinction though it's critical for scheduling. For sake of clarity, a Process runs a program, and may spawn 1 or more threads when it is multi-threaded. For me the distinction is all threads of a process use the same virtual address space. However for scheduling on a CPU that distinction is irrelevant. If I run P processes each with different Tp thread counts: - Process fairness: How can I guarantee a process with many threads won't use up all resources and overpower a process with only 1 thread? Formalized, fair scheduling would mean: process P should get 1/Pth of the CPU resource, and have that 1/Pth split evenly to 1/(Pth*Tp) per thread of P. Is it what CFS guarantees by default?
- Do I need autogroups? Autogroups allow a process to schedule groups of tasks together. By default there's one group, but if you spin a 2nd one it will get 1/2 the CPU, spin 10 and each group of threads gets 1/10th. Simple (see gang scheduling).
- multi-core: I do not care too much to muddy the answer with considerations on load balancing for multi-cores and process migration between cores.
Experimental result: CFS seems to be fair between processes. I tried on 4.9.27 to monitor the runtime of a small process vs a long running process with many threads. It seems that the scheduler on my kernel schedules by process, not by threads. So the small process was treated fairly and got 50% of the CPU. When I used 2 long running processes I got 33%. The slowdowns were like 2.2x and 3.4x respectively. This kernel doesn't seem to have autogroups compiled in; setsid() works but seems to do nothing, AND /proc/*/autogroup doesn't exist, so trying to use autogroup while CFS seems to do the right thing is an expensive undertaking. However some other data points seem to indicate sometimes the behavior is not fair to a process. Side question Is there a trick to guarantee one process will run more regularly than all others? I can't promote it to realtime because of LD_LIBRARY_PATH usage I believe. And even then, I suspect because it reads /proc to monitor the system, it sometimes still got delayed massively when the system is heavily over capacity. Thanks! |
| Start two X servers on boot on RHEL Posted: 31 May 2022 11:06 AM PDT I have a powerful machine that I want to use as a multi-seat system. It has two graphic cards and two pairs of keyboards and mice. I've been able to successfully configure two "seats" using udev and Xorg.conf, and launch two X servers from a script so two users can have independent sessions. Just for the record, here's my udev rules file, where I identify each USB hub and label the devices and the seats: SUBSYSTEM=="drm", KERNEL=="card[0-9]*", ATTRS{vendor}=="0x10de", DRIVERS=="nvidia", TAG+="master-of-seat" # SUBSYSTEM=="drm", KERNEL=="card0", ENV{ID_SEAT}="seat0" # SUBSYSTEM=="drm", KERNEL=="card1", ENV{ID_SEAT}="seat1" SUBSYSTEM=="input", ENV{ID_INPUT.tags}="input_default" # KVM HUBS KERNELS=="3-2", ATTRS{bDeviceClass}=="09", ENV{KVM_HUB}="1", ENV{ID_SEAT}="seat0" KERNELS=="3-8", ATTRS{bDeviceClass}=="09", ENV{KVM_HUB}="2", ENV{ID_SEAT}="seat1" # Devices of HUB 1 KERNEL=="event*", ENV{KVM_HUB}=="1", ATTRS{bInterfaceProtocol}=="01" SYMLINK+="kvm_keyboard_1" KERNEL=="event*", ENV{KVM_HUB}=="1", ATTRS{bInterfaceProtocol}=="02" SYMLINK+="kvm_mouse_1" # Devices of HUB 2 KERNEL=="event*", ENV{KVM_HUB}=="2", ATTRS{bInterfaceProtocol}=="01" SYMLINK+="kvm_keyboard_2" KERNEL=="event*", ENV{KVM_HUB}=="2", ATTRS{bInterfaceProtocol}=="02" SYMLINK+="kvm_mouse_2" # Default seat SUBSYSTEM=="input", TAG=="seat", ENV{ID_SEAT}=="" , ENV{ID_SEAT}="seat0" # set all tags accordingly ENV{ID_SEAT}!="", ENV{ID_INPUT.tags}+="$env{ID_SEAT}" TAG+="$env{ID_SEAT}"
The relevant part of my xorg.conf file looks like this: Section "ServerFlags" # Option "AutoAddDevices" "false" # Option "AutoEnableDevices" "false" Option "DefaultServerLayout" "Layout0" Option "AllowMouseOpenFail" "true" Option "Xinerama" "0" EndSection # --------------------------------------------------------------- # LAYOUT Section "ServerLayout" Identifier "Layout0" Screen "Screen0" MatchSeat "seat0" Option "Clone" "off" EndSection Section "ServerLayout" Identifier "Layout1" Screen "Screen1" MatchSeat "seat1" Option "Clone" "off" EndSection
As I said, I can successfully launch two independent sessions using the following script, but I'd like this to happen automatically on boot. #!/bin/bash set +x rm /etc/X11/xorg.conf cp ./xorg_independientes /etc/X11/xorg.conf # X (:0) systemctl stop gdm killall Xorg killall X systemctl restart gdm sleep 7 # X (:1) su - sit -c "startx /usr/bin/gnome-session -- :1 vt4 -layout Layout1 -seat seat1 -sharevts" & sleep 10 DISPLAY=:1 xhost +
My approach would be setting the default target runlevel to 4 (so it has everything but graphics) and then placing these commands in a script somewhere. |
| Nemo in Linux Mint - Reset all Preferences and "My computer" pane in List View Posted: 31 May 2022 10:00 AM PDT I am struggling a little bit with this issue I'm having with Nemo in Linux Mint (I just upgraded to 17.3 but this is happening since 17.1). In brief, I accidentally removed some shortcuts from the "My computer" section in the left sidebar of nemo as a user. I tried to restore them, nbut apparently I can't add icons to that tab, nor drag them from the "bookmark" section to the "My Computer" one. If I start nemo as root, I can add, remove, drag and drop icons in that tab, but of course the changings does not apply to the "user" version. Moreover, I tried to perform a clean install of nemo after purging it, but unsuccessfully. Can someone explain me where th configuration file of this sidebar are located and hot to delete them, or set their permission to user in order to drag and drop correctly into that tab? Alternatively, is there a "real" way to clean install Nemo and only Nemo without touching the other GTK features? Thanks a lot for your time, any help is really appreciated! |
| Is it possible to limit the set of English locales on a system? Posted: 31 May 2022 11:26 AM PDT On Debian and Ubuntu is it possible to limit the locales which have to be configured? I know that /var/lib/locales/supported.d/local and /var/lib/locales/supported.d/en govern which locales are being configured, but short of manually modifying it more or less after the fact (i.e. after an apt-get dist-upgrade) I haven't found any method to limit it to en_US.* locales as desired. So whenever the packages language-pack-en and language-pack-en-base gets touched (and they usually get updated in lockstep, from what I saw), I get something like this: Setting up language-pack-en (1:14.04+20150219) ...

Unfortunately some upgrades seem to override those two aforementioned files and thus reset modifications I've made to them. What'd like to see instead is: Setting up language-pack-en (1:14.04+20150219) ... Setting up language-pack-en-base (1:14.04+20150219) ... Generating locales... en_US.UTF-8... up-to-date Generation complete.

UPDATE - Install on mini210s w/ linux 3.0.8 armv7l target When I try this: # LD_PRELOAD=/lib/libc-2.13.so;/lib/libresolv-2.13.so ./chrome -v Segmentation fault
How do get more information about the reason of this segmentation fault? $ file ./chrome ./chrome: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, not stripped
How do I know whether this compiled file should run on my SBC w/ linuc 3.0.8 armv7l? Also asked on chromium-dev group UPDATE Tried to install on BeagleBone Black root@beaglebone:~/chromium# uname -a Linux beaglebone 3.8.13-bone67 #1 SMP Wed Sep 24 21:30:03 UTC 2014 armv7l GNU/Linux
I am getting the same segmentation fault root@beaglebone:~/chromium# ./chrome Segmentation fault
Determine file type root@beaglebone:~/chromium# file chrome chrome: ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, BuildID[sha1]=0x99f2a5210e0831419cf2bb4c9c64839cf03673f4, not stripped
