Hi, I recently received this board and I was able to get the docker started. Maybe someone may find it useful.
After installing via "armbian-confix" if try to start docker service with
$ systemctl start docker
we get this error:
● docker.service - Docker Application Container Engine
Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
Active: activating (auto-restart) (Result: exit-code) since Tue 2021-08-24 20:09:34 MSK; 26ms ago
Docs: https://docs.docker.com
Process: 11947 ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock (code=exited, status=1/FAILURE)
Main PID: 11947 (code=exited, status=1/FAILURE)
dpkg: error handling package docker-ce (--configure):
installed docker-ce package post-installation script subprocess returned error exit status 1
In "journalctl -xe" we get the following - "Running iptables --wait -t nat -L -n failed with message: `# Warning: iptables-legacy tables present, use iptables-legacy to see them\niptables: Operation not supported.`, error: exit status 1."
And to fix it, you need to use the following command:
$ update-alternatives --set iptables /usr/sbin/iptables-legacy
Then restart the service and docker works.
