MarsSeed [1] filed a deletion request for cuda-11.0 [2]: Unmaintained, abandoned legacy build from 2020. There are some issues with its packaging, as per last user comment made in 2021. But not needed to keep: Arch developer and TU @dbermond maintains the one minor release newer version of this: https://aur.archlinux.org/packages/cuda11.1 [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/cuda-11.0/
