need help: unmet dependencies
Dear all, I don't know much about linux and need your kind help. My son's Raspberry Pi 4B's OS is "Debian GNU/Linux 12 (bookworm)" (from "/etc/os-release"). Yesterday I tried to run "apt update" "apt upgrade", but it stuck at upgrading package "chromium-browser" (The progress status bar froze; cannot ssh to it anymore; although I still can ping it). I had to shut it down and reboot it. I tried it several times but it always stuck whenever trying to install the package. I also got the following warning: You might want to run 'apt --fix-broken install' to correct these. The following packages have unmet dependencies: chromium-browser : Depends: chromium-codecs-ffmpeg-extra (= 126.0.6478.164-rpt1) but 122.0.6261.89-rpt1 is to be installed or chromium-codecs-ffmpeg (= 126.0.6478.164-rpt1) but it is not going to be installed Recommends: chromium-browser-l10n but it is not going to be installed E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution). When I ran "apt --fix-broken install", I got the following message: The following additional packages will be installed: chromium-browser chromium-codecs-ffmpeg-extra The following packages will be upgraded: chromium-browser chromium-codecs-ffmpeg-extra But when I continued with the installation, it froze again: Reading changelogs... 33% What should I do? My "/etc/apt/sources.list" is quite simple: deb http://deb.debian.org/debian bookworm main contrib non-free non-free-firmware deb http://deb.debian.org/debian-security/ bookworm-security main contrib non-free non-free-firmware deb http://deb.debian.org/debian bookworm-updates main contrib non-free non-free-firmware Thank you very much!

help: apt stuck at 0% [Waiting for headers]
Dear friends, I need some help here. I worked in a university and have a linux (debian 9) machine with DHCP. For some reason I needed a static IP and two weeks ago the university sent someone who helped me set up the static IP. From what I saw the file they modified is the "/etc/network/interfaces". However, I found that now I cannot update/install packages. "apt update" stuck at "0% [Waiting for headers]" for a long time and then give the following message: Ign:1 http://security.debian.org/debian-security stretch/updates InRelease Ign:2 http://ftp.us.debian.org/debian stretch InRelease Err:3 http://security.debian.org/debian-security stretch/updates Release Connection failed [IP: 151.101.50.132 80] Ign:4 http://ftp.us.debian.org/debian stretch-updates InRelease Err:5 http://ftp.us.debian.org/debian stretch Release Connection failed [IP: 128.61.240.89 80] Err:6 http://ftp.us.debian.org/debian stretch-updates Release Connection failed [IP: 128.61.240.89 80] Reading package lists...

N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. "apt list package_name" still gives information about the package, but "apt install package_name" is stuck at "0% [Waiting for headers]". The internet connection has no problem. DNS seems fine as well. I can ping for example security.debian.org or 8.8.8.8. My "/etc/apt/sources.list" file is: deb http://ftp.us.debian.org/debian/ stretch main contrib non-free deb-src http://ftp.us.debian.org/debian/ stretch main contrib non-free deb http://security.debian.org/debian-security stretch/updates main contrib non-free deb-src http://security.debian.org/debian-security stretch/updates main contrib non-free # stretch-updates, previously known as 'volatile' deb http://ftp.us.debian.org/debian/ stretch-updates main contrib non-free deb-src http://ftp.us.debian.org/debian/ stretch-updates main contrib non-free My other debian 9 machines with same sources.list file have no problems so I guess it must be related to the change of static IP. But I cannot figure out what is wrong. I have tried "apt clean" but it did help. Thank you very much! Michael

Dear friend, A simple and silly question: how to subscribe to this mail list and set up not to receive email? I only found a digest option when subscribing. Thank you very much. Michael
how to remove GUI
Dear friend, I recently installed Debian 9.13 on my machine. I was planning to use it for scientific computation so GUI is not necessary. For some reason, I installed the desktop environment with LXDE desktop during installation. Later I decided to remove them. These two commands were executed: tasksel remove desktop apt purge $(tasksel --task-packages desktop) However, after rebooting the system still has GUI. Here is the result of "tasksel --list-tasks": u desktop Debian desktop environment u gnome-desktop GNOME u xfce-desktop Xfce u kde-desktop KDE u cinnamon-desktop Cinnamon u mate-desktop MATE u lxde-desktop LXDE u web-serverweb server i print-server print server i ssh-serverSSH server u laptoplaptop So it seems the desktop package was removed. But why it still has GUI? It is pretty much an absolute clean installation. The only thing I did between OS installation and removing GUI is the installation of cuda package (for GPU driver). "nvidia-smi" gives: |0 1730 G /usr/lib/xorg/Xorg 132MiB | |0 2285 G kwin_x11 17MiB | |0 2292 G /usr/bin/krunner 2MiB | |0 2295 G /usr/bin/plasmashell 45MiB | |0 3091 G ...4-linux-gnu/libexec/kscreenlocker_greet 28MiB So plasmashell and x11 are not part of desktop? What is the correct way to completely remove GUI? Thank you. Michael

mount an external usb hdd and share it through samba
Dear all, I have an external usb hdd. I would like to automount it on boot and share it through samba. 1) So I put it in the fstab. It automounts correctly on boot, no problem: UUID=XXX /usb-hdd ext4 defaults,nofail 0 0 2) I then share the directory "/usb-hdd" through samba (in smb.conf) after it was mounted. No problem again: [usb-hdd] comment = raid5-usb path = /usb-hdd read only = No valid users = michaelm 3) however, if the machine restarts, automounts works but the samba share always fails. I can easily fix it by: systemctl restart smbd Since automount works, and samba will work well if I restart it, my guess is that on boot, samba (smbd service) starts before /usb-hdd is mounted. To make it working, I need make sure the fstab mounting happens before samba starts. Can anyone tell me how to do it? Or, any better solution for auto mount and share a usb HDD? Thank you very much.
