Code review comment for lp:~mterry/snapcraft/debian-packaging

Got the following when building with sbuild:

py3versions: no X-Python3-Version in control file, using supported versions
dh clean --with python3
   dh_testdir
   dh_auto_clean
Can't exec "pyversions": No such file or directory at /usr/share/perl5/Debian/Debhelper/Buildsystem/python_distutils.pm line 120.

From my system that is provided by python3-minimal, wonder if we need to manually depend on that instead.
