Title:
  14.10 to 15.04: Cannot handle manual dpkg --configure prompts

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

Bug description:
  The python script (and graphical interface) will hang when dpkg
  --configure (most likely, I was running dpkg --configure -a afterward)
  starts asking questions on how to proceed with changed config files.
  When there are a number of files that need to be updated, and the user
  has edited or changed some of them, even just a single one can cause
  the installer to completely hang. The button "Show Terminal" is or
  becomes unresponsive.

  After doing manual dpkg --configure -a, and rerunning the upgrader, it
  will say

  "Could not run the upgrade tool." (window title) --> "Could not run
  the upgrade tool. This is most likely a bug in the upgrade tool.
  Please report it as a bug using the command 'ubuntu-bug ubuntu-
  release-upgrader-core'." However, the report bug feature also fails:

  Traceback (most recent call last):
    File "/usr/share/apport/apport-kde", line 530, in <module>
      sys.exit(UserInterface.run_argv())
    File "/usr/lib/python3/dist-packages/apport/ui.py", line 650, in run_argv
      return self.run_report_bug()
    File "/usr/lib/python3/dist-packages/apport/ui.py", line 488, in run_report_bug
      response = self.ui_present_report_details(allowed_to_report)
    File "/usr/share/apport/apport-kde", line 367, in ui_present_report_details
      desktop_info)
    File "/usr/share/apport/apport-kde", line 184, in __init__
      self.ui.ui_update_view(self)
    File "/usr/share/apport/apport-kde", line 358, in ui_update_view
      QTreeWidgetItem(keyitem, [line])
  TypeError: index 0 has type 'bytes' but 'str' is expected

  For good measure: this was an upgrade from KUBUNTU 14.10 Utopic
  Unicorn.

  The output of apt-cache policy ubuntu-release-upgrader-core is:

  ubuntu-release-upgrader-core:
    Installed: 1:15.04.13
    Candidate: 1:15.04.13
    Version table:
   *** 1:15.04.13 0
          500 http://nl.archive.ubuntu.com/ubuntu/ vivid/main amd64 Packages
          100 /var/lib/dpkg/status

  But this is obviously after the upgrade. The system prior to upgrade
  was a regular 14.10 with a few minor tweaks.

  There is another error that popped up, it may be coming from muon-
  upgrader or that python thing at the same time as the other error
  (dialog) (popup) and that is that "Verifying the upgrade failed. There
  may be a problem with the network or with the server."

  (It appears as though after the dpkg --configure -a, my install is
  complete, ie. I have upgraded to Vivid. I have not rebooted yet
  though.)
