I installed manjaro on an old laptop today and am in the process of trying to update it.
pacman -Syyu eventually gave me
(383/383) checking keys in keyring downloading required keys... :: Import PGP Key KEY, "Brad Fanella <firstname.lastname@example.org>", created: 2018-03-2? [Y/n] Y error: key "Brad Fanella <email@example.com>" could not be imported error: required key missing from keyring error: failed to commit transaction (unexpected error)
I tried this sequence, to no avail:
sudo pacman-key --init sudo pacman-key --populate archlinux manjaro sudo pacman-key --refresh-keys sudo pacman -Syy sudo pacman -S manjaro-keyring archlinux-keyring sudo pacman -Syyu
pacman-key --recv-keys F382BBBD and got this:
gpg: key 81A402D4F382BBBD was created 6 days in the future (time warp or clock problem) gpg: key 81A402D4F382BBBD: no valid user IDs gpg: this may be caused by a missing self-signature gpg: Total number processed: 1 gpg: w/o user IDs: 1
