Dealing with the case that a package version was deleted from the archive

See LP: #1852389.

  • Base on what is appropriate; both the deleted version and the currently present version may be fine, depending on why the deletion was performed.

  • Rich history import won’t be affected; it just expects your changelog parent to match your rich history base, and that’ll generally be true anyway.

  • You can’t upload the same version that was deleted, so you may need to “jump” past that version. Exception: in a stable release, ubuntu1 -> ubuntu2 (deleted) -> ubuntu1.1 works.
