[Bug 1604173] Re: Clicking "Reboot Now" after 14.04-->16.04 upgrade has no effect

[Brian Murray]

The code seems to just call /sbin/reboot.  See
DistUpgrade/DistUpgradeController.py lines 1868 - 1871.  Could you try
calling that directly after the upgrade?  Thanks!

Title:
  Clicking "Reboot Now" after 14.04-->16.04 upgrade has no effect

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  After doing a 14.04 to 16.04 upgrade, clicking "Reboot Now" has no
  effect. update-manager simply closes. However, I could then reboot
  fine using the indicator or the power button, which kinda suggests the
  problem is in update-manager rather than in the general state of such
  an upgraded but not yet rebooted system.

  In the 3 test upgrades I did, this was reproducible 100% of the time.

  Steps I used to reproduce:

  1) Fresh install of 14.04.4

  2) Run updates and reboot

  3) Launch update-manager with `update-manager -d`

  4) Start upgrade, let it complete

  5) Once upgrade is completed, click "Reboot Now" on the shown dialogue

  FYI, thus far I've only tested on a UEFI system, haven't had time to
  test a BIOS system (and I wont likely have time to test on a BIOS
  system). But I wouldn't expect this to behave differently on a BIOS
  system.
