[Bug 1548858] [NEW] Trusty → Xenial upgrade window vanishes with no crash

[Dave Morley]

Public bug reported:

STEPS:
1. Install trusty .4 on a system/vm
2. Update
3. reboot
4. Hit Alt+F2
5. Type update-manager -d
6. You are invited to upgrade after that the window disappears and it is impossible to track if it completed

EXPECTED:
I expect to see the window at all times as the system upgrades

ACTUAL:
After you click on upgrade the update-manager window just disappears
Looking at top there is a Command reading xenial that is running at 100%cpu and doesn't stop.
