Title:
  python3-yaml and python3-six are not co-installable with python-is-
  python2 in jammy

Status in pyyaml package in Ubuntu:
  Fix Released
Status in six package in Ubuntu:
  Fix Committed

Bug description:
  The packages python3-yaml and python-is-python2 are not co-installable
  in jammy and I believe they should be.  This currently prevents me
  from upgrading one of my machines from focal to jammy.

  Further analysis with the help of Stefano Rivera revealed that what-
  is-python no longer produces a python-is-python2 package and the
  changelog hints at that being intentional.  Jammy still has a python2
  package, though.

  python3-yaml in jammy breaks on python (<2.7.18).  The python-is-
  python2 package in focal is version 2.7.17-4 and in impish it is
  2.7.18-9 and thus will be forcefully removed when going to jammy.
