How we can fix it?
which version did you run before the upgrade? are there any custom modifications?

try to upload the servicepack again, does this help?
We've upgraded from Proxmox Mail Gateway 4.0-14.
No custom modifications.

The server runs on Proxmox VE 3.4-6 as VM.

We tried to upgrade it again, same error. Please see attached log file.
