[Bug 1947977] [NEW] 'ubuntu-minimal' could not be located during release upgrade

[Wesley Tokoi]

Public bug reported:

The release upgrade from 20.04 to 21.04 kept failing because some
foreign packages were installed. After I attempted removing the said
packages - using the "Software & Updates" GUI tool, the upgrade failed
because "the essential package 'ubuntu-minimal' could not be located on
the system".
