[Bug 1350416] Re: Trusty -> Utopic release upgrade reportedly fails

[Erick Brunzell]

@ Grizzly, you really should have filed a new bug report as this
particular bug was fixed some time ago. There are many things that can
go wrong in the upgrade process, in your case it's possible that the use
of btrfs is not yet fully supported.

Title:
  Trusty -> Utopic release upgrade reportedly fails

Status in “ubuntu-release-upgrader” package in Ubuntu:
  Fix Released

Bug description:
  I repeated this twice, the last time beginning with a totally out-of-
  box Ubuntu GNOME 14.04.1 installation, fully updated, then ran the
  upgrade via "update-manager -d -c".

  The failure begins with a window saying:

  Could not install 'cgmanager'

  The upgrade will continue but the 'cgmanager' package may not be in a
  working state. Please consider submitting a bug report about it.

  subprocess installed post-installation script returned error exit
  status 1

  After clicking on the close button in that window just a minute or two
  later a new window appears that says:

  Could not install the upgrades

  The upgrade has aborted. Your system could be in an unusable state. A
  recovery will run now (dpkg --configure -a).

  Then after a substantial amount of time (30 to 45 minutes) a window
  appears that says:

  Upgrade complete

  The upgrade has completed but there were errors during the upgrade
  process.

  Time to reboot and see what I have.
