Public bug reported:
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):

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.)
