I recall having had this upgrade problem too, and fixing it manually after a few tries. But it's been a while, so this is not extensive...
The problem, as far as I narrowed it down, was the "gosa+samba3.schema" in my case -- renaming it to something not including a "+" fixed the original issue. The other issue is that /var/backups/VERSION is already there after the first upgrade try, so on subsequent tries it sadly fails instead of doing something more intelligent. hope this helps. -- ·'`’.
