From Screenlog.txt:

ERROR:root:No 'ubuntu-minimal' available/downloadable after sources.list rewrite+update

Ungültige Paketinformationen

After your package information was updated the essential package
'ubuntu-minimal' can not be found anymore so a bug reporting process
is being started.

[Brian Murray (brian-murray)]

The file not found message was about not being able to find 'apport-bug' to launch the bug reporting process.

[Swen Kühnlein (swen)]

Oops, the description wasn't really good. Indeed this bug is about expecting apport to be installed when it is not.

After manually installing apport, it reported that bug: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/964812
