OK, I was also missing gstreamer1.0-packagekit. Summary is:
For reproducing that exact error, have neither gstreamer1.0-libav nor gstreamer-1.0-plugins-bad nor gstreamer-1.0-packagekit. To fix the error, one needs both gstreamer1.0-packagekit and gnome- software, then hitting "Find in Software" will open gnome-software with suggestions (as attached). ** Attachment added: "Screenshot from 2024-04-12 11-46-48.png" https://bugs.launchpad.net/ubuntu/+source/totem/+bug/2060730/+attachment/5764166/+files/Screenshot%20from%202024-04-12%2011-46-48.png ** Also affects: app-center Importance: Undecided Status: New ** Changed in: totem (Ubuntu) Status: Triaged => Invalid ** Changed in: packagekit (Ubuntu) Status: New => Invalid ** Changed in: app-center Status: New => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2060730 Title: totem cannot install codecs via packagekit To manage notifications about this bug go to: https://bugs.launchpad.net/app-center/+bug/2060730/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
