TL;DR: distlib_hg and bandersnatch, you have a July 1st deadline to switch to Git or move off Bitbucket. https://bitbucket.org/blog/sunsetting-mercurial-support-in-bitbucket "we've decided to remove Mercurial support from Bitbucket Cloud and its API." "Mercurial features and repositories will be officially removed from Bitbucket and its API on July 1, 2020." Most of https://bitbucket.org/pypa/ is Mercurial repos. Maintainers of those repositories need to switch them to Git or move them off Bitbucket by July 1st. distlib_hg and bandersnatch are the active Mercurial repos that most clearly need to switch or move. A few repos in bitbucket.org/pypa have explicit "moved to GitHub" notices on them. And I assume its pkg_resources , setuptools, import_resources, pylauncher, and bootstrap projects are now defunct, but it's probably worth archiving them somehow anyway, for historical reference. -- Sumana Harihareswara Changeset Consulting https://changeset.nyc
