[Bug 807646] Re: failed to Upgrading Ubuntu 11.10 from Ubuntu 11.04

[Jean-Baptiste Lallement]

Thanks all for your comments but could you please all file separate
reports. Different dependencies resolution problems can lead to this
very error. Thanks in advance.

I'm closing this report because the original reporter said he finally
successfully upgraded but didn't attach the required logs.

  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.
