MarsSeed [1] filed a deletion request for kudus [2]: Defunct Qt3 and KDE3 based sudoku creator from 2015. Its dependency, kdelibs3 was last updated in 2015 and now has missing sources. I recommend deletion, as there are other sudoku tools. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/kudus/
