Some of the pipeline issues are due to #865, but there are some others that are due to the python version not available in Github Actions.

Versions not available are:

• 3.7.3
• 3.7.2
• 3.6.2
• 3.6.1
• 3.5.3
• 3.5.2
• 3.4

Some versions (like 3.4) can be fixed by specifying a sub version (ie 3.4.10 or 3.4.8), but I am unsure of the versions that you would need/like to have

Available versions can be found here: https://raw.githubusercontent.com/actions/python-versions/main/versions-manifest.json

I think we can drop all sub versions, except for 3.4, where we should just use the latest version.

Removed the sub-versions and bumped up 3.4 to 3.4.10

I'm not sure we can afford to drop the sub-versions; typing-extensions is tightly bound to the implementation of typing and unfortunately typing sometimes changes significantly between bugfix versions.

Unfortunately we are bound to the constraints here. It might be possible to request the python versions in the setup-python repo

Another option (but probably not recommended) would be to use the deadsnakes ppa to download the specific version of python we would need. But even the ppa doesnt have all python versions

[JelleZijlstra]

For now let's not worry about the micro versions then.

The Python 3.10 and linter failures are not related to this PR.

[srittau]

#868 for the linter warnings.

[adiroiban]

Thanks for the update.
I don't think the names are short enough :p

Another option is to use a custom name and add python version first

But I think that this can be merged as it is... as this is a very minor issue.
