MarsSeed [1] filed a deletion request for python2-incremental-git [2]: This is not a proper VCS package. Links to a versioned tarball instead of a git branch. Also, it does not declare its mandatory provides and conflicts.
Uploaded on 2021-05-17 and never got fixed. But no one requested such. This package is not required by anything. AUR now has the python2-incremental package. That can satisfy its consumer (python2-twisted). So I recommend to delete this package. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-incremental-git/
