Public bug reported: Running 13.10
> lsb_release -rd Description: Ubuntu 13.10 Release: 13.10 When I try to update, I get the following error: Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade. 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 As far as I can tell I do not meet any of the conditions above that would cause the failure. Tried to clean apt caches, and get same result.
