Outdated debmirror packages for Ubuntu

[Valter Jansons]

The debmirror package is shipped as 1:2.27ubuntu1 for Bionic 18.04 as
well as Focal 20.04. This released version (1%2.27 tag from July 2017)
does not have support for cnf (command-not-found) as discussed in the
bug report at https://bugs.launchpad.net/ubuntu/+source/debmirror/+bug/1821251

This bug was updated as Fix Committed back in March 2019. Looking at
the upstream repository at https://salsa.debian.org/debian/debmirror
the upstream change was indeed committed and included in upstream tag
1%2.32, pushed March 2019. Relevant individual commits are
292e9e9c999dbfa9cd0269c5b7c8f82af09300fc followed by
39055366f9cd4f161e451cf0621d52f7dc0d5126.

As a result, in Focal 20.04 LTS, running `apt-get update` on mirrors
deployed with the current `debmirror` installation results in an
error, as the cnf files do not exist.

Would it be possible to have the Ubuntu source/package updated to be
in line with the upstream Git repository, supporting Focal 20.04
clients?
