This is an artifact of of cygport creating python3-xxxx packages also for packages that never had a real package called like that. We had a discussion if it was worth to make the python3-xxxx pulling the python39-xxxx instead of python39-xxxx and it was decided against it. > I think this inconsistency is liable to cause confusion; it certainly > confused me until I worked out what was going on.

I expect no one looking for a package will look for obsolete packages. > Adam Regards Marco -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
