Hi! This was broken, as of today, on my machine: turns out for some reason, the lib is installed in /usr/lib/python3.10/site-packages, when my python interpreter is on version 3.11, so the package couldn't be found. I've tried uninstalling and reinstalling this, and it didn't help unfortunately; not sure what I'm doing wrong.
A workaround I've found was to force the PROJECT_ROOT_DIRECTORY variable to the above directory in the /usr/bin/ulauncher script.
@friday I followed the instructions from that link, i.e., paru -S ulauncher --rebuild, but I still get the same error.
I removed the AUR package, clone the repo and compiled from there, but still get the same error.
@nunonun you need https://archlinux.org/packages/extra/x86_64/python-cairo, but that's already declared as a dependency. So it's your system that's broken. See: https://github.com/Ulauncher/Ulauncher/issues/930#issuecomment-993434467
I got the following error:

Thank you @Misaka13514 The issue should be fixed now in 5.14.5.
Libnotify has been updated to 0.8.
https://github.com/Ulauncher/Ulauncher/blob/v6/ulauncher/utils/desktop/notification.py
You can edit 'Notify', '0.7' to 'Notify', '0.8' as temporary fix.

@Pound_Hash Please get the full log and verify it's not an issue with systemd. If not, post to https://github.com/Ulauncher/Ulauncher/discussions/categories/general if you need help.

When you update Python, you need to rebuild all python AUR packages, including Ulauncher.
