Package: thunderbird Version: 1:153.5.1esr-1~deb13u1 Severity: normal In this recent update, you removed "/etc/apparmor.d/usr.bin.thunderbird" but didn't remove "/etc/apparmor.d/disable/usr.bin.thunderbird" correctly.
You could remove symlinked "/etc/apparmor.d/disable/usr.bin.thunderbird" first, then remove "/etc/apparmor.d/usr.bin.thunderbird", then try to remove ""/etc/apparmor.d/disable/". I removed that broken symlink manually.
