[Bug 934371] [NEW] Unresolvable problem message results in less useful bug reports

[Brian Murray]

Public bug reported:

In UpdateManager/UpdateManager.py the following code exists:

    except SystemError, e:
        msg = ("<big><b>%s</b></big>\n\n%s\n'%s'" %
               (_("Could not calculate the upgrade"),
                _("An unresolvable problem occurred while "
                  "calculating the upgrade.\n\n"
                  "Please report this bug against the 'update-manager' "
                  "package and include the following error message:"),
                e)
               )

The upgrade may not be calculated for a couple of reasons.  As an
example we have:

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

update-manager knows, or should know, if you are upgrading to a pre-
release or running one and should notify the user to try again as this
may be due to archive inconsistencies rather than having them file a bug
right away.
