[Bug 1516194] [NEW] cannot upgrade to 15.10

[Naegling23]

Public bug reported:

I get an error trying to upgrade to 15.10 from 15.04.  When updating
15.04  I always get a partial upgrade notice, so I assume the two are
related.  I have disabled all third party sources, but it does not
appear to help the issue.
