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 Trisquel
* Running the current pre-release version of Trisquel
* Unofficial software packages not provided by Trisquel

but it is not telling me which applies, so I do notmknw which to attempt top remedy.

That last should read, I do not know which to attempt to remedy.

Now resolved. Uninstalled all teh non-free software I use and reinstalled it after the upgrade.
Linux-firmware is conflicted, but that is the subject of another bug report.
