Running postinstall tests on Debian 10 ("Buster") fails with the following errors when it tries to use docker-compose (pyhon based). Seems to be related to Python 2

Seems backport is install but needs to be copied to different location for it to work as done for ssl_match_hostname.

cp -r /usr/local/lib/python2.7/dist-packages/backports/shutil_get_terminal_size/ /usr/lib/python2.7/dist-packages/backports
