Hi @igoryonya thank you for your question. It seems that your docker setup isn't working. My guess would be, that your user is not part of the Docker group. (because of the Got permission denied while trying to connect to the Docker daemon socket)
See the Post-installation steps for Linux

The second part is strange maybe that can help: https://stackoverflow.com/questions/46036152/lookup-registry-1-docker-io-no-such-host/46037636
