[Bug 1044144] Re: Upgrade from kubuntu 12.04 to 12.10 failed using "sudo do-release-upgrade -d "

[afoglia]

I had a similar error.

update-manager -d failed with a KeyError.  Now update manager only
offers a partial upgrade and says "An upgrade from 'quantal' to
'precise' is not supported with this tool."

Running apt-get dist-upgrade -f now fails with:

dpkg-query: error: parsing file '/var/lib/dpkg/status' near line 15619 package 'libssl0.9.8:i386':
 mixed non-coinstallable and coinstallable package instances present
exim4-config.postinst: [WARN] Installed debconf version is broken. Aborting preconfigure.
dpkg: error: parsing file '/var/lib/dpkg/status' near line 15619 package 'libssl0.9.8:i386':
 mixed non-coinstallable and coinstallable package instances present
E: Sub-process /usr/bin/dpkg returned an error code (2)

Given that I wanted to upgrade to fix the buggy xserver-xorg version in
precise, I'm now downloading Debian testing.

Title:
  Upgrade from kubuntu 12.04 to 12.10 failed using "sudo do-release-
  upgrade -d "

Status in “ubuntu-release-upgrader” package in Ubuntu:
  Confirmed

Bug description:
  Running a 12.04 Kubuntu system (which was originally set up as a 11.10
  Ubuntu, then switched to KDE, then upgraded to 12.04).  Ran "sudo do-
  release-upgrade -d" since the "update-manager -d" was failing (which
  is a documented known bug).

  The release upgrader downloaded all packages and threw the following
  error:

  
  Processing triggers for man-db ...
  dpkg: error: parsing file '/var/lib/dpkg/status' near line 48205 package 'libibus-1.0-0:i386':
   mixed non-coinstallable and coinstallable package instances present
  Error in function: 

  
  A fatal error occurred 

  Please report this as a bug and include the files 
  /var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log in 
  your report. The upgrade has aborted. 
  Your original sources.list was saved in 
  /etc/apt/sources.list.distUpgrade. 

  SystemError: E:Sub-process /usr/bin/dpkg returned an error code (2)


  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). 

  Please report this bug in a browser at
