So there is not enough information to determine whether apparmor was involved, as it is only one source of permissions being denied. Seccomp, namespacing, etc can all result in permissions being denied.
grepping the kernel logs for DENIED would be the best way to check if there is an associated apparmor denial. In place re-installs should not be needed unless something is corrupted. Its possible on upgrades that the dbus service needs to be restarted, but that doesn't seem to have been tried here, at least not separate from the reinstall, which will also end up restarting the service. AppArmor related reasons that a restart of the service might be necessary, is that policy was added/changed in such a way that it conflicts with the current service. AppArmor will not change make label changes on a currently running service and that would require a restart. namespacing issues also could require a service to be restarted. Re-installs should only ever be needed for some config/on disk corruption, or if the service was stuck on an older version (couldn't update for some reason), and the re-install magically works. It could be that aptitudes version of reinstall is better than apts, but generally re-installing the service only works, if dependency issues are resolved first so that you can then actually update/install the new version of the package. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to language-selector in Ubuntu. https://bugs.launchpad.net/bugs/2049229 Title: dbus exception apt permission denied from gnome-language-selector Status in language-selector package in Ubuntu: Incomplete Bug description: Hi, I am reposting report https://github.com/UbuntuAsahi/ubuntu- asahi/issues/84 Running `sudo gnome-language-selector` leads to: ``` dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Spawn.ExecFailed: Failed to execute program org.debian.apt: Permission denied ``` This was resolved by reinstalling dbus. Feels like there was a user namespace issue which was resolved. Are in-place dbus re-installs needed? Is apparmor involved?
