Upgrade Problem: Could not perform immediate configuration on 'python-mlt5'.

Hi guys,

I use the pc on my workplace as proxmox server with X11-enhacement (Developer Workstations with Proxmox VE and X11). I was very satisfied with this solution.

So I want to upgrade this machine from 2.3 to the new version 3.0. I startet the script, and after ithe machen got over 2.000 files, the script stopped with this failure message:

Could not perform immediate configuration on 'python-mlt5'. Please see man 5 apt.conf under APT::Immediate-Configure for details. (2)

Does somebody has a idea what I can do fix this ?
