building ubuntu for qubes 3.2 fails due to PYBUILD_SYSTEM

[marti...@outlook.com]

Hi,

I try to build ubuntu bionic for Qubes 3.2 following the HowTo:
https://www.reddit.com/r/Qubes/comments/5vzg04/idiots_guide_to_installing_qbuntu_ubuntu_1604/

When I execute:
`make qubes-vm`

I get the error:
sudo BACKEND_VMM=xen chroot /home/user/qubes-builder/chroot-bionic su user -c 'cd /home/user/qubes-src/python-xcffib/debian-pkg/debian/..; export LC_ALL=C; debchange -t -l+bionicu "Build for bionic"; debchange -t --force-distribution -r -D bionic bionic; dpkg-buildpackage -sa -uc -us'

Setting
export PYBUILD_SYSTEM=distutils
in my local bash does not work, maybe because of chroot? I don't know python.
Could anyone tell me, what I need to do to get it running?

[unman]

This is a known issue and I'm working on it

Hi,
Ok, this is redundant to:
https://github.com/QubesOS/qubes-issues/issues/4330

Hence, I have modified:
chroot-bionic/home/user/qubes-src/python-xcffib/debian-pkg/debian/rules

#!/usr/bin/make -f
export PYBUILD_SYSTEM=distutils
DEB_BUILD_OPTIONS = nocheck

%:
dh $@ --with python2,python3 --buildsystem=pybuild

Unfortunately, I get now the error:

dpkg-build package: info: source changed by Marek Marczykowski-Górecki <*@invisiblethingslab.com>

dpkg-source --before-build debian-pkg
dpkg-buildpackage: info: host architecture amd64
fakeroot debian/rules clean
dh clean --with python2,python3 --buildsystem=pybuild
dh_auto_clean -O--buildsystem=pybuild

I: pybuild base:217: python2.7 setup.py clean

E: pybuild pybuild:336: clean: plugin distutils failed with: exit code=2: python2.7 setup.py clean

indeed, python-xcffib does not have a setup.py.

=> What do I need to do?

Thanks for your help!
