This note is relevant to running Arch Linux on Linode VMs
If you get asked to import maintainer keys and fail, or if you get package corrupt errors, do the following:
/etc/pacman.d/gnupg/gpg.conf
keyserver hkp://pgp.mit.edu:11371
pacman-key --init
pacman-key --populate archlinux
pacman -Syy
pacman -Syu
Hope this helps and enjoy your Arch instance on Linode!
