Could you please try this again? The empathy problem (that is the root
for many of the messages like this) is in the archive now and I can no
longer reproduce this particular failure (with the /var/lib/dpkg/status
file provided). If it stills fails for you (and you are using a up-to-
date mirror that has the latest empathy-common) then please attach
/var/lib/dpkg/status and I will try to rerproduce.

** Changed in: update-manager (Ubuntu)

Status in “update-manager” package in Ubuntu: Fix Released

Bug description:
Binary package hint: update-manager

I'm using Ubuntu Karmic, 9.10, and trying to upgrade to Lucid using
update-manager or do-release-upgrade fails with the following message:

{{{

Calculating the changes

Calculating the changes

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade:
E:Error, pkgProblemResolver::Resolve generated breaks, this may be
caused by held packages.

This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu

If none of this applies, then please report this bug against the
'update-manager' package and include the files in
/var/log/dist-upgrade/ in the bug report.

update-manager version is 1:0.126.9

Despite the fact it says the system was restored to the original state, my
sources.list has the lucid entries, instead of the karmic ones I had before
the upgrade attempt.
