kaneki [1] filed a deletion request for anki-sync-server-git [2]: The repo points to an community sync server that has not been updated since 2022 and no longer works with the latest version of anki. It has since been superceded by an official version that is more up to date and works with the latest builds of anki: https://aur.archlinux.org/packages/anki-sync-server [1] https://aur.archlinux.org/account/kaneki/ [2] https://aur.archlinux.org/pkgbase/anki-sync-server-git/
