Note: snap now vendors apparmor so reinstalling/removing the system apparmor package with not affect snapd's use of apparmor.
You can temporarily (for the boot) disable apparmor in the grub command line by adding apparmor=0 to the kernel parameters. >From the logs the following adjustments need to be done to snap policy, after fixing these new denials may be encountered. The firefox denial is weird, and I have to ask why is root trying to run firefox. The likely culprits are /snap/snapd/20671/usr/lib/snapd/snap-confine and snap.snapd-desktop-integration.snapd-desktop-integration. Can you try copying these profiles out of /var/lib/snapd/apparmor/profiles/ modifying them by putting flags=(complain) in the profile header, and then reloading them with sudo apparmor_parser -r profile.file. This will temporarily place these profiles in dev mode and if they are the source of the problem allow the graphics layer to come up. profile snap-update-ns.firefox /usr/local/share/ r, # owner root, fsuid root profile /snap/snapd/20671/usr/lib/snapd/snap-confine capability net_admin, capability perfmon, profile snap.snapd-desktop-integration.snapd-desktop-integration /etc/gnutls/config r, # owner root, fsuid 1000 /etc/gnutls/config r, # owner root, fsuid 1000 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apparmor in Ubuntu. https://bugs.launchpad.net/bugs/2052489 Title: Mate Daily Graphic Layer does not come up - apparmor denied snap desktop integration Status in apparmor package in Ubuntu: New Bug description: Noble Mate Daily 20230205 ISO Boots up past Splash to black screen.
