MarsSeed [1] filed a deletion request for libmateweather-gtk2 [2]: MATE-Gtk2 is EOL since 2017, and the majority of its components fail to build on current Arch Linux. Not useful to keep this package. Arch repo carries the latest working version. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/libmateweather-gtk2/
