The log files to first examine when looking at distribution upgrades are
VarLogDistupgradeMainlog.txt and VarLogDistupgradeAptlog.txt.  Mainlog
contains general information about the upgrade and Aptlog contains
information about the package problem resolver[0].  The error message[1] in
the referenced bug is generic and doesn't indicate what the actual
problem is.  To determine the particular issue the user encountered
you'll need to read VarLogDistupgradeAptlog.txt.  Looking at just a
couple of the duplicates of bug 1241123 they are not all the same issue
and a bug pattern is not necessary here.

This is a bit out of date (as is it is missing information on the split
between update-manager and ubuntu-release-upgrader) but the log files
and their formats are the same.

[1] 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
