MarsSeed [1] filed a deletion request for arduino-mk-git [2]: Broken VCS package from 2017, for demo/template code which is not useful to have as an installed package. The source should be forked and used as a starting point for Arduino development. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/arduino-mk-git/
