I believe this started for me when I upgraded from noble to oracular. After upgrading I was able to start the Firefox snap (by accident, I thought I still had the deb version installed), but after removing the Firefox and Thunderbird snaps, and removing then reinstalling some of the framework/library snaps (I don't remember exactly which ones) now it appears none of the snaps (Firmware Updater, Security Center, etc.) can start.
Plus my logs are filled with apparmor and snap messages because snapd- desktop-integration and prompting-client tries (and fails) to start every few seconds. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2084099 Title: so many apparmor denied messages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/2084099/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
