[Bug 875703] Re: Oneiric upgrade broken - Exception during pm.DoInstall(): E:Internal Error, Could not early remove liblcms1

[Tom Shorrock]

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)
