MarsSeed [1] filed a deletion request for pynetfilter_conntrack [2]: Orphaned package for a Python 2 module. (Python 2 bindings for [core] libnetfilter_conntrack and userspace cli tool for the same.) The source was last updated in 2016 and supports only Python 2. This package's name is not ideal, should have been prefixed with 'python2-'. Nevertheless, there is nothing on AUR that would depend on this package, and currently it cannot be packaged because of an already deleted Python 2 based dependency. I don't think this package is needed anymore or worth keeping. The upstream Netfilter project does provide native userspace tools for the main library, in the form of the conntrack-tools package (available in [extra]). I think it's safe to say this Python 2 module from 2016 is deprecated and obsolete. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/pynetfilter_conntrack/
