Comment 1 for bug 1780827

Python 3.7 has introduced incompatibilities for a lot of projects, but I feel it will be difficult to tackle these until we have a stable test environment for it. So this will probably have to wait until the next Ubuntu LTS release that includes 3.7 (or newer?) as default python3 version.

Testing with python3.6 on 18.04 I fail to see the deprecation warnings mentioned in the PEP, so I don't see how we could act on these at the current state.
