Hello Everyone,
DTS has operated using the version of python available in the oldest
supported Ubuntu LTS for a while now, but after some discussion in the
working group, we decided that DTS should designate a Python version
explicitly for the sake of compatibility. My initial proposal is Python
3.6, due to Ubuntu 18.04 LTS shipping with it by default. Currently, the
Community CI Lab runs Python 3.8 on all testers (Ubuntu 20.04 LTS), but for
the sake of compatibility a lower python version might be desirable.
The working group is specifically looking for reasons to not use Python 3.6.
The Community CI Lab perspective is that versions higher than 3.8 are not
acceptable due to the issues with changing the default Python installation
on Ubuntu. This may be raised to 3.10 in June of this year after we have
had time to evaluate the 22.04 release of Ubuntu.

Python 3.6 reached end of life in 2021.

I guess only reason to specify a (max) supported Python version is the environment in community lab. So, if someone submits a patch that requires a newer version, it should be caught in the CI. This should enable us to reject such a patch.

After some discussion in the working group, we decided that this is mostly
a question of what the labs can support. The UNH Lab uses the version of
python that ships with the latest Ubuntu LTS, which is 3.8. The Intel Lab
is in a similar situation. Are there any objections to python 3.8 with
updates trailing Ubuntu LTS by a few months for stability reasons?
