** Description changed:
+ [Impact]
+ As documented in bug 1766890 some system were having failing to upgrade due
to trigger issues with gnome-menus and ubuntu-release-upgrader was modified to
upgrade libc6 first because that would fix that. However, in some rare cases
this causes an issue for apt's problem resolver and the upgrade can't be
calculated. Instead of leaving people on an unsupported we should try and
upgrade them the way we used to - by not upgrading libc6 first.
+
+ [Test Case]
+ We actually haven't found a situation where upgrading libc6 first will create
a issue for apt's problem resolver, but testing upgrades to ensure there are no
regressions should be sufficient. Additionally, we can watch the bucket in the
Ubuntu Error Tracker (referenced below) to ensure that the new version of
ubuntu-release-upgrader doesn't appear there.
+
+ [Regression Potential]
+ A typo in the new code could cause a different Traceback, but it all looks
good to me.
