I tried to reproduce this and was unable to. The apparmor package did
added a Breaks: media-hub, mediascanner2.0, messaging-app, webbrowser-
app because of bug #1756800 and bug #1761176 so I tried upgrades with
and without these installed. Test configurations:
* Ubuntu Desktop default install
* update sources.list to include bionic and run apt-get update
* apt-get upgrade correctly holds apparmor
* apt-get dist-upgrade correctly upgrades apparmor
* revert changes to sources.list and run apt-get update
* do-release-upgrade -d correctly upgrades apparmor. Package
removal at end does not suggest removing apparmor. Reboot
shows apparmor is installed
* Ubuntu Desktop default install with media-hub, mediascanner2.0,
messaging-app and webbrowser-app installed
* update sources.list to include bionic and run apt-get update
* apt-get upgrade correctly holds apparmor
* apt-get dist-upgrade correctly upgrades apparmor and removes
media-hub, mediascanner2.0, messaging-app and webbrowser-app
* revert changes to sources.list and run apt-get update
* do-release-upgrade -d correctly upgrades apparmor and removes
media-hub, mediascanner2.0, messaging-app and webbrowser-app.
Package removal at end does not suggest removing apparmor.
Reboot shows apparmor is installed
* Ubuntu Server default install
* update sources.list to include bionic and run apt-get update
* apt-get upgrade correctly upgrades apparmor (no Breaks
installed so no reason to hold)
* apt-get dist-upgrade correctly upgrades apparmor
* revert changes to sources.list and run apt-get update
* do-release-upgrade -d correctly upgrades apparmor. Package
removal at end does not suggest removing apparmor. Reboot
shows apparmor is installed
* Ubuntu Server default install with media-hub installed
* update sources.list to include bionic and run apt-get update
* apt-get upgrade correctly holds apparmor
* apt-get dist-upgrade correctly upgrades apparmor and removes
media-hub
* revert changes to sources.list and run apt-get update
* do-release-upgrade -d correctly upgrades apparmor and removes
media-hub. Package removal at end does not suggest removing
apparmor. Reboot shows apparmor is installed
I believe that the apparmor removal has nothing to do with the new added
Breaks in 18.04's apparmor, however, as mentioned, I cannot reproduce.
Can you provide steps to reproduce?
