Comment 6 for bug 1879708

This got fixed with subiquity 20.06.1 and is also listed in the release notes:
https://github.com/CanonicalLtd/subiquity/releases/tag/20.06.1
It's probably best to use this now based on a 20.04 daily live image:
http://cdimage.ubuntu.com/ubuntu-server/daily-live/current/
Or you need to make sure that an installer upgrade is performed.

Closing this ticket as Fix Released (from a project point of view).
