restart docker and no luck

Your Docker installation is not using a supported storage driver. If we were to proceed you may have a broken install.aufs is the recommended storage driver, although zfs/btrfs/overlay and overlay2 may work as well.
Other storage drivers are known to be problematic.
You can tell what filesystem you are using by running “docker info” and looking at the ‘Storage Driver’ line.If you wish to continue anyway using your existing unsupported storage driver,
read the source code of launcher and figure out how to bypass this check.
