pacman -Rs docker # remove docker and unused dependencies
pacman -S docker
level=fatal msg="bad listen address format /var/run/docker/libcontainerd/docker-containerd.sock, expected proto://address"
This appears to have been caused by a recent upgrade to containerd-0.2.3-1-x86_64. Fortunately I had the previous version available at /var/cache/pacman/pkg/containerd-0.2.2-1-x86_64.pkg.tar.xz.
Downgrading the containerd package solved the problem for me:
pacman -U /var/cache/pacman/pkg/containerd-0.2.2-1-x86_64.pkg.tar.xz
Posting here incase anyone else is seeing the same issue.
