Please could someone affected confirm that, without any workaround, reverting to the previously published package resolves the issue, and that upgrading back causes it to arise again? Then we can gain some confidence that reverting the update is an appropriate course of action.
It looks like the previously published package version was 4.0.0-beta3-0ubuntu3 and this is the version in the release pocket. In a default installation I believe that only apparmor and libapparmor1 are installed on vanilla Ubuntu. If this the case, you should be able to revert with: sudo apt install apparmor=4.0.0-beta3-0ubuntu3 libapparmor1=4.0.0-beta3-0ubuntu3 You will be warned about a downgrade, but should receive no other warnings (if you do receive any other warnings I suggest you do not proceed). To find the definitive list of packages that need downgrading you can run this but you'd need to install the dctrl-tools package first: grep-status -S apparmor|grep-dctrl -F Status installed -ns Package Or you can consult /var/log/apt/history.log to understand what exactly was upgraded. See also bug 2064672 (thanks @g2p!) for details of the testing performed on the package prior to release. It would be helpful if you could participate in that bug to help us improve testing for next time - both in improving our coverage of the QA steps performed, and in validating the eventual fix if we do revert, to help us avoid regressing the package again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2072811 Title: Apparmor: New update broke flatpak with `apparmor="DENIED"` To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2072811/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
