when trying to run

docker run hello-world

Kept getting:

connect: network is unreachable

Solved problem by changing /etc/resolv.conf to

nameserver 8.8.8.8

Perhaps the usual 192.168.0.1 nameserver can't properly handle the docker registry server. Which is:

https://registry-1.docker.io/v2/library/hello-world/manifests/sha256:ac69084025c660510933cca701f615283cdbb3aa0963188770b54c31c8962493
