The Problem: you try to login into docker registry and unable to authenticate due to storing credentials error.
Error saving credentials: error storing credentials - err: exit status 1,
out: `Post "http://ipc/registry/credstore-updated":
dial unix /var/root/Library/Containers/com.docker.docker/Data/backend.sock:
connect: no such file or directory`
