MarsSeed [1] filed a deletion request for firebird-superserver [2]: Defunct package, not updated since 2019. Missing one of the source files. There are maintained Firebird server packages on AUR so this old one seems not to be needed. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/firebird-superserver/
