Public bug reported: After upgrading to Ubuntu 18.04, the apparmor service is failed on boot because of unresolvable references from /etc/apparmor.d/usr.bin .webbrowser-app, from the removed (but not purged) webbrowser-app package.
The package itself was removed from my system as part of the upgrade to 17.10, but the presence of the obsolete conffile did not cause problems until upgrading to bionic. I think the apparmor package needs to take care to clean up after these abandoned conffiles on upgrade.
