Bug#939109: pyhoca-gui: Python2 removal in sid/bullseye -- drop python-distutils-extra build dependency

[Martin Pitt <mpitt@debian.org>]

Package: src:pyhoca-gui
Version: 0.5.0.8-1
Severity: normal
Tags: sid bullseye
User: debian-python@lists.debian.org
Usertags: py2removal

Python2 becomes end-of-live upstream, and Debian aims to remove
Python2 from the distribution, as discussed in
https://lists.debian.org/debian-python/2019/07/msg00080.html

Your package build-depends on python-distutils-extra. Please convert the
package to Python 3, using python3-distutils-extra.

Thanks,

Martin
