Python 3.6.x is EOL and no longer supported.

Describe the bug
Python 3.6 is end-of-life and appears to be breaking installation of salt-lint?

Invalid specifier: '>=3.6.*'

This seems key. We're also effected, even though we're not running 3.6 (at least, I hope)

Yah, the culprit looks to be here: https://github.com/warpnet/salt-lint/blob/main/setup.py#L61

After forking the repository and replacing that with 3.8, I still observe the same behavior.

Noticed this bug in our CI pipeline today and tracked it as an intended change from packaging: pypa/packaging#645

The fix is probably to drop the *: python_requires='>=3.6'

Thanks @czyszCTDS your suggestion. Let's give you suggestion a try, removing the wildecard (*) shouldn't have any impact on the accepted version numbers as both >=3.6 and >=3.6.* should be equal.

The updated python_requires definition has been released in v0.9.2.

Thank you! I can confirm the new version installs properly in our CI environment.
