A package should use 'ubuntu' version numbering if it originated in Debian
and its source has been modified in Ubuntu.

Ubuntu binary packages differ from Debian binary packages with the same
version number, but this is expected and not a bug.  Mixing Debian and
Ubuntu binary packages on the same system is doomed due to limitations and
assumptions in the packaging system, and is therefore unsupportable.
