Upgrade from 11.04 to 11.10 fails: E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

[Ville Herva]

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 using the command 'ubuntu-bug update-manager' in a terminal.

* Not running pre-release, this is up-to-date 11.04
* not upgrading to pre-release, target is the released 11.10
* third party stuff is disabled

dpkg --get-selections | grep -i hold
returns nothing.

dpkg --configure -a
returns nothing

Thanks for taking the time to report this bug and helping to make Ubuntu better. Could you please add the log files from '/var/log/dist-upgrade/' to this bug report as separate attachments? Thanks in advance.

[Ville Herva (v-iki)]

Here are the files from /var/log/dist-upgrade .

[Jean-Baptiste Lallement (jibel)]

Thanks for the logs. It confirms that it is a duplicate of bug 874220, and I'm marking as such.
The workaround is to remove libsublime1 and then try upgrading again.

[Ville Herva (v-iki)]

Yes, removing libsublime1 helped. Thanks.
