Gpodder doesn't start anymore on Ubuntu 24.04 : ModuleNotFoundError: No module named 'imp'

[Valeryan24]

Hi, since a few days, Gpodder (last deb version from repositery) doesn't launch anymore on Ubuntu 24.04 (beta version in development) :
"[gpodder.log] ERROR: Uncaught exception: Traceback (most recent call last):

There is a major bug related to AppArmor in Ubuntu, which prevents many programs to start, could it be related to this or is it something different ?

https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2046844

AppArmor user namespace creation restrictions on Ubuntu cause many applications to crash with SIGTRAP or SIGSEGV.
Ubuntu recently decided to disable unprivileged access to user namespaces. You can find more information it about it here:
https://ubuntu.com/blog/ubuntu-23-10-restricted-unprivileged-user-namespaces

"You can enable user namespaces by either making a apparmor profile for your installs, making sure the directory where the program is installed is correct in the profile, or by just enabling user namespaces for your system."

Thanks !

You are using python 3.12 and gpodder 3.11.4 does not support it. You need to have the package maintainer apply dd9b594 and 510de4b to make it work.

I will apply the patches and upload to Debian. Will there be a released version that includes these changes soon?

Updated Debian version tested against Python 3.12: https://tracker.debian.org/news/1512534/accepted-gpodder-3113-2-source-into-unstable/

would it make sense to release an unstable ppa from master ?

[auouymous]

I would like to get a release out soon. I'm going to try applying a patch only to the Windows build that removes the python 3.12 support in hopes it fixes the build.

This landed on Arch too. Is there a lot of work to be done?

[patrickuhlmann]

It works again on Arch if the file "/usr/lib/python3.12/site-packages/gpodder/extensions.py" is edited according to dd9b594. Would be nice if this could be integrated tough.

I have just pushed a fix to the Arch Linux package, next time also feel free to report this earlier to our Bugtracker aswell (was submitted yesterday) when there already is a commit to backport. 🤗

Should these be used only with python312 or it gonna still work with earlier ones too?

[auouymous]

@barracuda156 They work with 3.11. The importlib patch needs 3.5, so it will work with all supported versions. I assume setuptools has always had setup, so it should also work, but I don't know.

[barracuda156]

Thank you. On the next update we can make the patch unconditional then. For now I just added it when building with python 3.12: macports/macports-ports@d78f2d5
