[Dan Christensen]

I installed version 3.28.1-0ubuntu3 of gnome-session-bin gnome-session-common
and ubuntu-session from bionic-proposed, and the problem went away.

(When I upgraded from 16.04 to 18.04, do-release-upgrade stopped with an error,
so I did the rest of the upgrade manually.)

[Brian Murray]

Hello helboof, or anyone else affected,

Accepted gnome-session into bionic-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/gnome-
session/3.28.1-0ubuntu3 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

[Bug 1720310] Re: unity-gnome-shell-migration.18.08.py crashed with signal 5 in g_object_new_valist() due to gnome-shell-extension-ubuntu-dock not installed

[Didier Roche]

** Description changed:

+ [Impact]
+ 
+  * People having this particular setup:
+- removed ubuntu-desktop metapackage from their system
+- upgrading from 16.04 to 18.04 (or previously to 17.10) by manually 
editing /etc/apt/sources.lists without using do-release-upgrade (which 
reinstalls ubuntu-desktop).
+ 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.

In response to #7: I responded to a call to help test the transition to
Gnome early in the development cycle. It was before Ubuntu Dock was even
a thing.

the error is

how did you upgrade? gnome-shell-extension-ubuntu-dock which includes
that schemas should be installed on upgrades
