I installed Debain 12 about a month ago, and kept having difficulties with the package manager. It seems to lack any sort of sources in its default configuration, so that I had to manually add some which I saw online to the sources file. By default, the sources file only refered to some cd-rom thing, even though I installed the OS with a usb stick. Currently I am trying to install blender with apt, but as many times before, apt finds the program, but not the dependencies. The output I get from sudo apt install blender
is this:
marty@MartyPC:~$ sudo apt install blender

Im very sorry for the german output (if anyone knows how to change only the terminal language to english, I would appreciate if they could tell me how to). It essentially says this:
Some packages cannot be installed. That can meean, that an impossible situation was requested, or that an unstable distro is used and that the required packages have not been created yet. The following information may help solve the problem:
These packages need unmet dependencies:
blender:
needs libavcodec58 (>= 7:4.0)
[...]
If anyone has suggestions for fixing this promblem, I would appreciate it very much if they could share their thoughts.
It’s hard to guess what is wrong with your configuration. Show your
sources
.To disable translation for commands you run in terminal, do
export LANG=C
.Well… Right off the bat, I can see what the problem is. You have totally mixed up entries for different releases of debian in there. It’s a wonder it hasn’t completely broken your system.
It kinda has multiple times. I tried installing a Wayland version of gnome and that ended up nuking the Desktop multiple times. Then to fix it, I just ran this in a TTY: sudo apt remove gnome sudo apt install gnome And that fixed the desktop (even my wallpaper and shortcuts were back, wow).
And yes, I will update my sources to suit my OS.
In case it is needed, here is my current sources.list content:
# deb cdrom:[Official Debian GNU/Linux Live 12.1.0 gnome 2023-07-22T09:48:34Z]/ bookworm main non-free-fi> # deb http://ftp.us.debian.org/debian stretch main contrib non-free deb http://security.debian.org/debian-security buster/updates main contrib non-free deb http://deb.debian.org/debian buster-updates main contrib non-free deb https://deb.debian.org/debian/ trixie main non-free contrib non-free-firmware deb-src https://deb.debian.org/debian/ trixie main non-free contrib non-free-firmware # deb https://dl.winehq.org/wine-builds/debian/ buster main
You have entries for different debian releases but no entry for the one you actually installed (
bookworm
). Change this todeb https://deb.debian.org/debian/ bookworm main contrib non-free-firmware non-free deb https://deb.debian.org/debian/ bookworm-updates main contrib non-free-firmware non-free deb https://security.debian.org/debian-security bookworm-security main contrib non-free-firmware non-free
Then run
apt update
andapt dist-upgrade
to update all packages that you installed from older repos. Thenapt autoremove
to remove packages that are not longer needed.After that you may still have to downgrade packages installed from
trixie
repos or remove them if they are not inbookworm
. To do this, edit your/etc/apt/preferences
file (create it if it does not exist) and addPackage: * Pin: release n=bookworm Pin-Priority: 1001 Package: * Pin: origin "" Pin-Priority: -10
Then run
apt dist-upgrade
andapt autoremove
again. When all packages are downgraded, remove these lines from/etc/apt/preferences
.For more details, refer to the documentation:
In some cases it can be easier to simply reinstall the OS avoiding mistakes that you did.
You might be able to fix it by picking the most recent of all the mixed releases and running a dist-upgrade. But this is absolutely not supported or tested. But a complete reinstall is certain to fix it.
You need to not be using
buster
/trixie
/stretch
in your sources first of all. switch all instances ofbuster
,trixie
, andstretch
tobookworm
, then do anapt update
and try again.This is what my sources.list looks like for reference (I have enabled
non-free
andnon-free-firmware
which you may or may not want, and I also have the backports repo enabled):deb http://deb.debian.org/debian/ bookworm main contrib non-free non-free-firmware deb http://security.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 deb http://deb.debian.org/debian/ bookworm-backports main contrib non-free non-free-firmware
it sounds your installation wasn’t completely finished or idk, but your system shouldn’t be in this state in the first place - unless you messed with it.
It really started out with no apt sources. I didn’t mess with that until I realized that they are missing.
could be either broken installer or maybe there was no Internet connection… or not netinst image
either way, if I were you, it would really bug me and reinstall the whole system 😆
