MarsSeed [1] filed a deletion request for python2-lz4 [2]: Upstream discontinued Python2 support 2.5 years ago. Nothing depends on this legacy package. As Python 2 itself is EOL since Jun 2020, I recommend deleting this. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-lz4/
