They end up with: - no ubuntu-dock installed - and consequentely, the settings migration script would trigger an apport dialog (crashing) due to lack of gsettings schema. * Even if this is an unsupported case (people shouldn't cowboy sources.list and use our upgrader tools), we can easily prevent this crash, ignoring settings migration in such a case. [Test Case] 1. Install 16.04 2. Remove ubuntu-desktop metapackage 3. Change your sources.list from "xenial" to "bionic" 4. apt update && apt full-upgrade 5. Reboot and log into a new session once upgrade is done. -> you won't get the ubuntu-dock, but the session migration script shouldn't crash. [Regression Potential] * The script was crashing (even if there is no settings to migrate, so it was a no-op). We prevents gsettings to segfault by guarding for schema existence in the standard way. ------ Upgrade...
