Error when provisioning for Ubuntu 20.10 "Groovy"

Hi,
I try to use docker-machine for Ubuntu 20.10 distribution, but get this error Package 'docker-ce' has no installation candidate. Debug output is here:

About to run SSH command:
if ! type docker; then curl -sSL https://get.docker.com | sh -; fi
SSH cmd err, output: exit status 100: bash: line 0: type: docker: not found

It looks like Docker provides a repo for Ubuntu Groovy: https://download.docker.com/linux/ubuntu/dists/groovy/.
Do I miss something or is it an issue?
Thanks

After comparing https://download.docker.com/linux/ubuntu/dists/focal/ and https://download.docker.com/linux/ubuntu/dists/groovy/ I see that there is no InRelease file in stable channel (only in test).
I guess this is the answer.
Any plans to make docker available in stable channel?
