MarsSeed [1] filed a deletion request for cameramonitor [2]: Orphaned Python 2 based package. Development discontinued in 2012. Broken because one of its Py2 dep has no source available. So I recommend to delete this abandoned package. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/cameramonitor/
