system upgrade fails.

[Johnny Arthur]

No extra ppa's however some problems already with former updates (probably with nvidia drivers, which i deinstalled and installend nouveau manually, but only an upgrade to lunar solved the display problems). Cannot find out what is missing/going wrong now when trying to update to mantic.
