Bug Description

Just wanted to upgrade my Natty to Oneiric via do-release-upgrade:

But this just fails with this message - token from screenlog:

Systemaktualisierung wird durchgeführt
start: Job is already running: apport
^MFetched 0 B in 0s (0 B/s)

Exception during pm.DoInstall(): E:Internal Error, Could not early remove liblcms1
Keine aktuellen Absturzberichte. Versuchen Sie --help für weitere Informationen.

Die Aktualisierungen konnten nicht installiert werden

Don't know what the error is - but i am unable to upgrade and my system is left in a broken state now - anything i can do to find the "culprit" why upgrade fails here?

Found this one:

https://bugs.launchpad.net/ubuntu/+source/apt/+bug/802901

After doing apt-get -f install + apt-get install apt to get the latest oneiric one, do-release-upgrade does continue and does not fail with an Internal Error.
urgency=low for this critical fix does not seems right to me if upgrade does fail because of this bug.

for what its worth, I had exactly the same problem. The following fixed it for me:

dpkg --force-all -r liblcms1

I could then rerun do-release-upgrade.

(I'm not an expert and so I cannot promise that the above is good advice, but thought it might help a maintainer)

I actually had the same problem on one of my machines, and I searched for it everywhere but couldn't really seem to understand why apt-get couldn "early remove" liblcms1 ... after some searching I stumbled upon this bug https://bugs.launchpad.net/ubuntu/+source/apt/+bug/802901 which is kind of the same problem. Here this guy had arm libraries installed on his system, so on my system which is x64 I had also x86 libs installed, so what I did was

sudo apt-get remove nspluginwrapper (for some reason I had to uninstall this first in order to uninstall ia32-libs)
sudo apt-get remove ia32-libs
sudo apt-get update && sudo apt-get dist-upgrade

and it should work again
