Greetings. I'm new to Rancher Desktop (having came from Docker Desktop) and I'm running into an issue when using nerdctl to build an image from a Dockerfile. Namely, I get this error (I issue a nerdctl build . command): error: failed to solve: ubuntu:18.04: failed to do request: Head "https://registry-1.docker.io/v2/library/ubuntu/manifests/18.04": dial tcp 34.205.13.154:443: i/o timeout FATA[0030] unrecognized image format The first line in the Dockerfile is, unsurprisingly, FROM ubuntu:18.04 This built fine in Docker Desktop. What am I missing?

-> #rancher-desktop

Are you running a apt-get as the next command? I think the docker image network might not be up to run apt yet
