Trying to pull a Docker image results in a signature error.
Raw
docker-out-of-space.sh
# Errors similar to this:
# Err:4 http://archive.ubuntu.com/ubuntu bionic-backports InRelease
# At least one invalid signature was encountered.
# Probably mean Docker ran out of space (and the error is completely unhelpful).
docker builder prune -f # This may be enough
# If that didn't help
docker image prune # add -f or --force to not prompt for confirmation
docker container prune # add -f or --force to not prompt for confirmatio
# Optionally (removes the data!)
docker volume prune
# Check the Docker system disk usage
docker system df
# A more radical approach:
docker system prune
