Hi,

Would you mind providing a few details about your setup to help in identifying the cause of your error? What distribution are you running? Are you on GCE, EC2, Azure vm, Virtual box, VMware,... ? What networking policy/firewall you have setup? 

My setup on GCE, 2 vCPU instances, Ubuntu 16.04 LTS and 18.04 LTS produce a similar error only if I run the docker install command without an apt-get update before.

To find if docker.io is available to install for your distribution you can try 

apt-cache pkgnames

or

apt-cache search

Depending on the distribution, a different docker installation approach may be required, based on their official documentation.

Regards,

Hello,

I've seen this error when using Suse, and had to enable a particular backport to get it to work. Could you verify which version of Ubuntu you are using?

I came across the same error. I am still working on to resolve. But meanwhile, you can install Docker through the Linux distros installation script. Quite an easy and straightforward

curl -sSL https://get.docker.com/ | sh

In order that you have the least amount of issues, I would encourage you to use the suggested version and OS. Of course once you have the labs down, trying to get them to work in other places is encouraged.
