| Version `ZLIB_1.2.9' not found (required by libpng16.so.16) in Debian Posted: 21 Aug 2021 09:45 AM PDT I know this is basically the exact question as in https://stackoverflow.com/questions/48306849/, but the answer there does not seems right to me, as they all saying creating a libz.so.1 symlink. However, In my Debian bullseye, I already have libz.so and libz.so.1, both symlinking to libz.so.1.2.11. So this seems to be a problem that libpng16.so.16 insists on a lower version of ZLIB (v1.2.9), while mine is already v.1.2.11, right?

| Debian Live USB error. Help? Posted: 21 Aug 2021 08:24 AM PDT So I have a laptop (Dell G3 3779) with Windows 10 and Pop OS installed (both are on seperate hard drives). Recently, I installed some Dell UEFI Firmware update though Windows 10 and everything was working fine. Both Windows and Pop OS booted normally. I wanted to delete my Pop OS installation and replace it with Debian 11, so I downloaded one of the nonfree (unofficial) ISOs and burned it to a flash drive. However, when I entered my boot menu to boot from that live USB, it goes to a black screen with the following error message: set_second_stage() failed: Invalid parameter Something has gone seriously wrong: shim_init() failed: Invalid parameter Then it shuts off. I don't know why this happened, as I've installed Debian and booted from USB before, so maybe the firmware update did something? Secure Boot is Disabled, so I'm not sure how to fix this issue. I've also tried installing other Debian ISOs like the live install version (nonfree) but the same thing happens. How do I fix this?  |

| Is it possible to get gnu-screen instance to print output to the monitor of the PC running it? Posted: 21 Aug 2021 08:15 AM PDT I have a little raspbery pi running a twitter bot. I have programmed it to print some bits of info to the terminal when it does the job successfully, fails or waits. I launch the application via SSH using gnu-screen to keep the app running even if I disconnect from ssh session. My question is - is it possible to configure screen in such a way that I can launch it via SSH but have it print it's output to the display connected to the rapsberry pi? Currently even though I can launch the app vis SSH and screen, all I see on the pi is the login prompt (terminal only raspberry os lite).  |
| Preparing debian iso file for usb Posted: 21 Aug 2021 07:54 AM PDT I downloaded debian 11 from this address. And i downloaded the firmware from this address. Then i wrote the following commands from linux terminal. sudo umount /dev/sda1 sudo dd if=/dev/zero of=/dev/sda sudo fdisk /dev/sda sudo mkfs.vfat /dev/sda1
I formatted the usb. (W95 fat32) Then i downloaded the iso file and copied it into this usb. sudo dd if=/PATH/debian-11.0.0-amd64-netinst.iso of=/dev/sda bs=4M status=progress && sync
It's over. However, i need to add firmwares into this usb. How can i do that? I couldn't find anything about my problem on the internet. I checked the usb if it is working properly and it is working.  |

| zsh completion: complete _values, but case-insensitive Posted: 21 Aug 2021 06:47 AM PDT I have the following completion script to complete a list of roles: host /usr/share/zsh/vendor-completions # cat _foo #compdef foo local -a values=('ROLE_ADMIN[Admin]' 'ROLE_USER[User]') _values -s , 'roles' $values
This works fine so far; it'll complete the roles: host ~ # foo ROLE_<TAB> roles ROLE_ADMIN -- Admin ROLE_USER -- User
But I want the completion to work case-insensitively, ie. if I type now type ad after ROLE_, I want it to complete ROLE_ADMIN, which doesn't work. I've figured out that I need to use compadd -M with a match-spec like 'm:{[:lower:]}={[:upper:]}', but I can't figure out how to pass this to _values which doesn't seem to support -M.  |
| Different scales for join displays? Posted: 21 Aug 2021 06:06 AM PDT Is it possible to have different scales for join displays? I tried the solution suggested here: gsettings set org.gnome.mutter experimental-features "['x11-randr-fractional-scaling']" but it didn't do anything. I have a laptop (with Debian 11 and Gnome 3 X11) with a 4K display and I got a second (portable) 1080p monitor. For the main display, in Settings->Displays, I put a Scale of 200%. When I connect the second monitor, it works fine, but also has the 200% Scale, which makes it unusable. I have the option to change the scale of the second monitor back to 100%, but then that automatically puts the scale of the primary display to 100% as well.

| Problems installing Manjaro with RTX 3080 Laptop GPU Posted: 21 Aug 2021 06:27 AM PDT I have gotten a new laptop as my old one has gotten quite old. The new laptop is the ROG Zephyrus G15 with the RTX 3080. The first thing I did was download the XFCE version of Manjaro from their website. But when I tried installing it always stopped loading when it got to the graphical interface. I am guessing that this is due to the 3080 not being supported natively. How would I install this driver without having Linux installed?  |
| Is it possible to make a device accessible exclusively by certain programs? Posted: 21 Aug 2021 06:35 AM PDT I have a device (a video card) that I need only two programs (expressed as paths, e.g. /usr/bin/myprogram) to access. The device has a /dev file (e.g. /dev/mydev1), but I can also use other references if required (bus id, vendor/product id etc.). Is there anything that I can do (e.g. udev rules), that prevents any program from access, except the ones I specify?  |

| Re-number and rename Posted: 21 Aug 2021 07:43 AM PDT I got into a situation that I need to rename lots of files in the form of: file.csv file_1.csv file_2.csv file_3.csv file_4.csv file_5.csv file_6.csv file_7.csv file_8.csv
To better order, i.e.: file_1.csv file_2.csv file_3.csv file_4.csv file_5.csv file_6.csv file_7.csv file_8.csv file_9.csv
I.e., I can manually rename the first file, but for the remaining "_#" files, I need to renumber them with +1. I tried to use rename -n -v 's/_(.*)./.(\1+1)./'
but got file_(1+1).csv file_(2+1).csv
etc. Any easy way to batch remain the "_#" files please? PS, better as file_01.csv . . . file_09.csv file_10.csv . . .
if possible. UPDATE: Thanks to cas' answer. Because I'll rename them as zero-padded names, so there won't be conflict in file names, so to me the command can be simplified as: touch file.csv file_{1..9}.csv $ rename -v 's/^(file_)(\d+)(\.csv)$/$1 . (sprintf "%02i", $2 + 1) . $3/e' file_* file_1.csv renamed as file_02.csv file_2.csv renamed as file_03.csv file_3.csv renamed as file_04.csv file_4.csv renamed as file_05.csv file_5.csv renamed as file_06.csv file_6.csv renamed as file_07.csv file_7.csv renamed as file_08.csv file_8.csv renamed as file_09.csv file_9.csv renamed as file_10.csv
Note the last two file names: file_09.csv file_10.csv

| What is the point of btrfs subvolumes? Posted: 21 Aug 2021 08:40 AM PDT The system administrator guide of the Btrfs wiki (here) says: A Btrfs subvolume can be thought of as a POSIX file namespace. I remember at first it saying that a subvolume is, as opposed to being able to be thought of as, a "POSIX file namespace". A Google search for "POSIX file namespace" turn up only things about Btrfs, so the phrase is unhelpful. Just what is a subvolume in Btrfs? If a subvolume is accessible as a directory from the filesystem root, then how is mounting subvolume any different from bind mounting a directory on any other filesystem to another location without intermediately mounting the root of said filesystem? This is what I mean: # standard bind mount mkdir /mnt/data mkdir /mnt/docs mount /dev/sda2 /mnt/data mount --bind /mnt/data/docs /mnt/docs umount /mnt/data rmdir /mnt/data # hypothetical method of directly mounting # a file/directory on a filesystem # to some path that achieves the same # as the above mkdir /mnt/docs mount -o path_on_fs=/docs /dev/sda2 /mnt/docs # if /docs on sda2 was a subvolume mkdir /mnt/docs mount -o subvol=/mnt /dev/sda2 /mnt/docs
What is the purpose of the subvolume feature? An example: /var/lib/machines.raw is a Btrfs filesystem image that is used by systemd-machined and machinectl to store virtual machines and/or containers. Presumably, Btrfs is used for subvolumes. What do the subvolumes do for that? If a subvolume is useful for containers, does it have built-in isolation for processes running in different subvolumes?  |

| How to unload kernel module 'nvidia-drm'? Posted: 21 Aug 2021 06:12 AM PDT I'm trying to install the most up-to-date NVIDIA driver in Debian Stretch. I've downloaded NVIDIA-Linux-x86_64-390.48.run from here, but when I try to do sudo sh ./NVIDIA-Linux-x86_64-390.48.run
as suggested, an error message appears. ERROR: An NVIDIA kernel module 'nvidia-drm' appears to already be loaded in your kernel. This may be because it is in use (for example, by an X server, a CUDA program, or the NVIDIA Persistence Daemon), but this may also happen if your kernel was configured without support for module unloading. Please be sure to exit any programs that may be using the GPU(s) before attempting to upgrade your driver. If no GPU-based programs are running, you know that your kernel supports module unloading, and you still receive this message, then an error may have occured that has corrupted an NVIDIA kernel module's usage count, for which the simplest remedy is to reboot your computer.
When I try to find out who is using nvidia-drm (or nvidia_drm), I see nothing. ~$ sudo lsof | grep nvidia-drm lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs Output information may be incomplete. ~$ sudo lsof -e /run/user/1000/gvfs | grep nvidia-drm ~$
And when I try to remove it, it says it's being used. ~$ sudo modprobe -r nvidia-drm modprobe: FATAL: Module nvidia_drm is in use. ~$
I have rebooted and started in text-only mode (by pressing Ctrl+Alt+F2 before giving username/password), but I got the same error. Besides it, how do I "know that my kernel supports module unloading"? I'm getting a few warnings on boot up related to nvidia, no idea if they're related, though: Apr 30 00:46:15 debian-9 kernel: nvidia: loading out-of-tree module taints kernel. Apr 30 00:46:15 debian-9 kernel: nvidia: module license 'NVIDIA' taints kernel.

| `source .../settings.csh` not working from `sh ./test.sh` Posted: 21 Aug 2021 07:05 AM PDT I want to source Xilinx ise setiin64.csh file with the source command. I have source /home/xilinx/ise_14.5/14.5/ISE_DS/settings64.csh
in another file, test.sh. So I want to run only test.sh file as sh ./test.sh
But I am not getting Xilinx ISE 14.5 version when I do which ise. If I execute command source /home/xilinx/ise_14.5/14.5/ISE_DS/settings64.csh
directly in terminal then it works fine.  |
| Can't get docker to forward ports Posted: 21 Aug 2021 09:05 AM PDT I've been following a tutorial to try and learn docker, however, for some reason I can't seem to access any of the ports it's meant to be opening. For some reason it just times out. Where can I look to get more details on why I'm not able to access this, or otherwise what can I do access the docker container. Steps done so far: $ docker run hello-world # works fine $ docker run -d -P --name static-site prakhar1989/static-site # works and returns a docker container id $ docker port static-site 443/tcp -> 0.0.0.0:32768 80/tcp -> 0.0.0.0:32769
Then I access one of the host through http://localhost:32768/ but nothing. After reinstalling it doesn't even time out anymore and just says the site can't be reached. Also, I tried accessing the container directly on those ports but without any success.  |

| Reply on same interface as incoming? Posted: 21 Aug 2021 06:34 AM PDT I have a system with two interfaces. Both interfaces are connected to the internet. One of them is set as the default route; a side effect of this is that if a packet comes in on the non-default-route interface, the reply is sent back through the default route interface. Is there a way to use iptables (or something else) to track the connection and send the reply back through the interface it came from?  |
