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

Problem was solved by install accountsservice.

Now, if output will be useful:
desktop:~$ apt-cache policy libaccountsservice0
libaccountsservice0:
  Installed: (none)
  Candidate: (none)
  Version table:
     0.6.15-1~natty1 0
        100 /var/lib/dpkg/status
