vivid upgrade hangs, if system files have been changed before

[themroc]

upgrade GUI hangs, if system files have been changed in past, for example \etc\default\openvpn etc.

My Workaround:

Find upgrade process: Not easy and to complicate for beginners
kill upgrade process

open terminal
sudo dpkg --configure -a
sudo reboot

Status changed to 'Confirmed' because the bug affects multiple users.

Note, the upgrade process freeze if you have to decide to keep or replace a global config file.

e.g.:
Package distributor has shipped an updated version.
     What would you like to do about it ? Your options are:
      Y or I : install the package maintainer's version
      N or O : keep your currently-installed version
      D : show the differences between the versions
      Z : start a shell to examine the situation
   The default action is to keep your current version.
  *** <file of interest> (Y/I/N/O/D/Z) [default=N] ?
