please port ubuntu-system-service to Python3

Hi Didier,

I tried building system-service from the branch, and this is what I saw:

 dpkg-buildpackage -rfakeroot -d -us -uc -S
dpkg-buildpackage: source package ubuntu-system-service
dpkg-buildpackage: source version 0.3
dpkg-buildpackage: source distribution wily
dpkg-buildpackage: source changed by Steve Langasek <email address hidden>
 dpkg-source --before-build ubuntu-system-service-0.3
 fakeroot debian/rules clean
dh "clean" --with translations,python3 --buildsystem python_distutils
   dh_testdir -O--buildsystem=python_distutils
   dh_auto_clean -O--buildsystem=python_distutils
pyversions: missing X(S)-Python-Version in control file, fall back to debian/pyversions
pyversions: missing debian/pyversions file, fall back to supported versions
Traceback (most recent call last):
  File "setup.py", line 6, in <module>
    from DistUtilsExtra.command import *
ImportError: No module named DistUtilsExtra.command
dh_auto_clean: python setup.py clean -a returned exit code 1
debian/rules:4: recipe for target 'clean' failed
make: *** [clean] Error 1
dpkg-buildpackage: error: fakeroot debian/rules clean gave error exit status 2

Is this the behavior you saw at the time you prepared this patch?

Since the package doesn't appear to be uploadable in its current state, resetting the bug status.

I don't think this was the case, I did a build+dogfooding on all packages that I ported to python3 at the time, still weird that DistUtilsExtra thingy as I remember to have fiddle with dependencies.

I'll probably look at that later on.

any update on this?

I'm unsure anyone on the desktop team took the time to look at it. I think it should be doable on the 16.04 LTS timeframe though

Taking a shot at this.

This bug was fixed in the package ubuntu-system-service - 0.3

---------------
ubuntu-system-service (0.3) xenial; urgency=medium

  [ Didier Roche ]
  * bump upstream version to 0.3
  * port tests and binaries to python3 (LP: #1440388)
  * Keep some python2 build-deps to get the package built.
  * Bump Standards-Version to latest

  [ Martin Pitt ]
  * debian/rules: Only build/install for the default python3, not for all
    supported versions. This is only a private module, the interface is D-Bus.
