Help needed installing anki on xubuntu [linux]

[stupid]

@tracker

Qt info: Could not load the Qt platform plugin “xcb” in “” even though it was found.

This is the important part.

I’m guessing that you’re using xfce because you’re on Xubuntu. I searched for xfce and found a user with the same error as above, but on Debian: Anki 23.12.1 fail to start in Debian 12

Dae linked to this page: Missing Libraries - Anki Manual. It says to launch with QT_DEBUG_PLUGINS=1 anki to add debug output in order to see which library is missing.

In that user’s case, dae saw that libxcb-icccm.so.4 was missing via the end of the last line starting with Qt debug:

@miku4j

Qt debug: QLibraryPrivate::loadPlugin failed on "/usr/local/share/anki/lib/PyQt6/Qt6/plugins/platforms/libqxcb.so" : "Cannot load library /usr/local/share/anki/lib/PyQt6/Qt6/plugins/platforms/libqxcb.so: (libxcb-icccm.so.4: cannot open shared object file: No such file or directory)" 

and a search for the required package gave libxcb-icccm4:

@dae

% apt search libxcb-icccm     
Sorting... Done
Full Text Search... Done
libxcb-icccm4/stable,stable,now 0.4.1-1.1 amd64 [installed]
  utility libraries for X C Binding -- icccm

I’d still try to follow those steps instead of going straight to installing the package. Try to find a similar error message using QT_DEBUG_PLUGINS=1 anki and then find out what package provides/owns the missing library.

In case the apt search command shown above doesn’t work for you, I did a few searches. On my OS, the search I’d use is pacman -Qo <missing-library> pacman -F <missing-library> to find which package owns it. This page gives the equivalent in Debian/Ubuntu: pacman/Rosetta - ArchWiki

pacman -Qo equivalents likely incorrect in this case, see edit below

dpkg -S <missing-library>

OR

dlocate <missing-library>

Edit: I tested. libxcb-icccm.so.4 showed up by using pacman -F, not pacman -Qo. So the command in that case would be:

apt-file search <missing-library>

Man pages:
dpkg
dlocate
apt-file
