Trying to run `poll-upstream-sources` pipeline on an el8 node ends with an error:
After an attempt of resolving the issue by installing python2 and setting the unversioned python command to point to python2 we fail on dependencies:
A quick look at the `usrc.py` script shows we need at least 3 deps:
python2-pyxdg (or simply pyxdg)
The last package is not available at all in el8 repos.
Please provide a solution to this problem by either moving the script to use py3 or any other means.
