# pacman-key --refresh--keys
  • pacman-key –list-keys
  • pacman-key –list-sigs

If the key is found on a keyserver, import it with:

# pacman-key –recv-keys keyid

If otherwise a link to a keyfile is provided, download it and then run:

# pacman-key --add /path/to/downloaded/keyfile

It is recommended to verify the fingerprint, as with any master key or any other key you are going to sign:

$ pacman-key –finger keyid

Finally, you must locally sign the imported key:

# pacman-key –lsign-key keyid

Wroking example:

# pacman -Syy --noconfirm pacman-mirrorlist archlinux-keyring haveged
# pacman-key --init
# pacman-key --populate
# pacman-key --recv-keys B0391223A038F085
# pacman-key --lsign-key B0391223A038F085

# cat << _EOF_ >> /etc/pacman.conf
