No you did not read the output and carried on without giving it any
thought.

It's always possible there are some bugs somewhere in the marking, we
had some breakage in dailys that have been resolved in the meantime.
Given that you have not provided any data for the actual bug, just an
outlandish suggestion (please run apt-mark minimize-manual after that to
get to a sensible state), this bug is incomplete.

Also reassigning it to ubiquity instead of apt, as ubiquity is the thing
installing it, might also have been an issue in livecd-rootfs, but who
knows without data?

I think you can attach additional information with apport-collect
1915793, but I'm not sure it includes relevant data. If not, please
attatch the files in /var/log/installer.

Title:
  Suggested fix for apt installed packages catalog problem

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  After fresh install, running sudo apt-get autoremove results in 30+ packages (over 700mb) being suggested for removal. I innocently did this and ended up with my Plasma desktop being removed.. 
  Luckily I had a snapshot of a VM to go back to...

  However, This could be a jarring experience for less experienced users
  installing Daily build of Studio 21.04

  A simple fix is to run this command post-install for the Daily Build:

  sudo apt-mark manual $(sudo apt-get -s autoremove 2>/dev/null | awk
  '/^Remv / { print $2 }')

  What this command does is marks all packages marked autoinstall to
  'manual install'.

  This way while you all are adding-on things at the last minute it
  doesn't cause a problem if a new user innocently runs autoremove.

  Then when ready for release remove the above command from post-
  install.
