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](https://forums.ankiweb.net/t/anki-23-12-1-fail-to-start-in-debian-12/42129)

[Dae](https://forums.ankiweb.net/u/dae) linked to this page: [Missing Libraries - Anki Manual](https://docs.ankiweb.net/platform/linux/missing-libraries.html). 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:`

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

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](https://wiki.archlinux.org/title/Pacman/Rosetta)

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

```bash
apt-file search <missing-library>

```
