MarsSeed [1] filed a deletion request for lxd-lts [2]: Orphaned package. Last updated ~4 years ago. As such, I recommend deletion. Arch repo carries the latest lxd, and nothing depends specifically on this lts package. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/lxd-lts/
