MarsSeed [1] filed a deletion request for sia-ui [2]: Legacy dependency 'gconf' on gcc 14. Release archive deleted by upstream (404 not found). Seems discontinued. Upstream website does not mention any 'Sia-UI'. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/sia-ui/
