No, I couldn't find a way to make it work so, after a while, I just gave
up and reinstalled with the new version.

Title:
  Upgrade from 10.10 to 11.04 fails because of isc-dhcp-client

Status in “update-manager” package in Ubuntu:
  Confirmed

Bug description:
  When trying to upgrade from Ubuntu 10.10 to 11.04 update-manager fails
  with the following message:

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

  I'm attaching files from '/var/log/dist-upgrade/'.

  I don't get any output from the command 'dpkg --get-selections | grep
  hold'.

  A dist-upgrade from the terminal gives me the following output:

  $ sudo apt-get dist-upgrade
  Reading package lists... Done
  Building dependency tree
