Issues with running install.sh script for k3s

Hello,

I’m trying to run k3s installation script on Ubuntu 18.04 (described here: Rancher Docs: Installation) and I cannot see docker images when script is done, although install script (install.sh as described in linked instructions) executes successfully and binary is downloaded.

If I try some docker command after the installation I get:

#docker save -o pause.img docker.io/rancher/pause
Error response from daemon: No such image: docker.io/rancher/pause

Do you know what could be the issue?

BR,
Ivan
