Title:
  git clone shows "Host key verification failed" on lunar lobster docker
  image

Status in git package in Ubuntu:
  Invalid

Bug description:
  I run a script in a lunar docker image that clones a git repository
  from 'git.launchpad.net'

  While docker image build I install the git package. The script then runs the following command:
  ssh-keyscan -t rsa git.launchpad.net >> $HOME/.ssh/known_hosts

  This creates the following output:
  # git.launchpad.net:22 SSH-2.0-Twisted_20.3.0+lp9

  As exptected, and $HOME/.ssh/known_hosts contains the key, as expected. But then I run:
  git clone ssh://imker@git.launchpad.net/samba-exporter

  And get the following output:
  Cloning into 'samba-exporter'...
  Host key verification failed.
  fatal: Could not read from remote repository.

  Please make sure you have the correct access rights
  and the repository exists.
  Error: Can not clone the launchpad repo ssh://imker@git.launchpad.net/samba-exporter

  Until now this script has work within docker for any Ubuntu version
  since Focal, so I assume there is something wrong the the git package
  in lunar lobster.

  The docker file I use to get the lunar image showing this error can be
  found here:

  package/build/LaunchpadPublish/Dockerfile.lunar
