From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Because of something I did during an anthropology lecture, I learned the hard way to read the "The following packages will be REMOVED" list when upgrading a package to backports in Debian GNU + Linux. (lemmy.ca)

  1. I suspended the computer, and after resume, the lock screen was broken:
  • When I clicked on the password field, the text cursor only appeared for a split second, and I could not type in it
  • Clicking on the user switch button on the bottom right corner did nothing
  • A few times, the text "Authentication error" randomly appeared for a split second, probably for 1 frame
  • No way to reboot the normal way, because I could only use the power menu on the lock screen, which only has suspend
  1. I used the power button to reboot, and instead of GNOME, there was darkness

  1. I reinstalled systemd (not sure if this made a difference)
Start-Date: 2024-09-18  15:48:58
Commandline: apt install --reinstall systemd
Requested-By: dullbananas (1000)
Reinstall: systemd:amd64 (252.30-1~deb12u2)
End-Date: 2024-09-18  15:49:02
  1. I reinstalled gdm3, and immediately without me doing anything else, there was GNOME instead of darkness
Start-Date: 2024-09-18  15:51:49
Commandline: apt install --reinstall gdm3
Requested-By: dullbananas (1000)
Install: gnome-remote-desktop:amd64 (43.3-1, automatic), gnome-shell:amd64 (43.9-0+deb12u2, automatic), power-profiles-daemon:amd64 (0.12-1+b1, automatic), gdm3:amd64 (43.0-3), gstreamer1.0-pipewire:amd64 (0.3.65-3+deb12u1, automatic), chrome-gnome-shell:amd64 (42.1-3, automatic), gnome-session:amd64 (43.0-1+deb12u1, automatic), gnome-browser-connector:amd64 (42.1-3, automatic), gnome-shell-extension-prefs:amd64 (43.9-0+deb12u2, automatic)
Remove: tlp:amd64 (1.5.0-2), tlp-rdw:amd64 (1.5.0-2)
End-Date: 2024-09-18  15:52:05

  1. End of class

  2. I reinstalled tlp because installing gdm3 removed it

  3. After selecting an app search result, instead of a new window opening, an existing window was focused, and this led to me discovering that my built-in extensions were gone

  4. While writing this post, I got the idea of using the list of removed packages in the apt history log output from apt install libpipewire-0.3-0/bookworm-backports to see what packages to install again, so I did that, then I also had to uninstall firefox-esr again

  5. I rebooted, and my built-in extensions and other stuff were resurrected, so now I have full redemption

  6. Another Window Session Manager restored my windows in a way that pissed me off

(Failed attempts of recovery are not listed)

Edit: actually I made the mistake 1 minute before the start of class
