[Bug 1881337] Re: 'ubuntu-minimal' could not be located. LTS 18.04 to 20.04

[Brian Murray]

The mirror of the Ubuntu archive you use is not an official one and
subsequently the release upgrader disabled it.

2020-05-29 19:52:04,649 DEBUG entry '# deb
http://mirror.onet.pl/pub/mirrors/ubuntu/ focal main universe restricted
multiverse # disabled on upgrade to focal' was disabled (unknown mirror)

Please switch to an official mirror of the Ubuntu archive and try the
upgrade again.

** Changed in: ubuntu-release-upgrader (Ubuntu)
       Status: Confirmed => Incomplete

  Invalid package information

  After updating your package information, the essential package 
  'ubuntu-minimal' could not be located. This may be because you have 
  no official mirrors listed in your software sources, or because of 
  excessive load on the mirror you are using. See /etc/apt/sources.list 
  for the current list of configured software sources. 
  In the case of an overloaded mirror, you may want to try the upgrade 
  again later.
