We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Ubuntu 20.04 - platform.dist()  is deprecated since Python 3.5 and removed in Python 3.8
Affected distro - ubuntu 20.04 (use python 3.8)
Affected case - WALA-VERIFY-VERBOSE-ENABLED-LOGS
Use distro.linux_distribution(full_distribution_name=False) instead

--- END ISSUE ---
