Need help - Failed docker install on Ubuntu 18.04

Hello, I’m not sure where else to post this. It’s my first time trying to setup docker.

I was following the online instructions to install and setup docker on Ubuntu. I got up to the part " INSTALL DOCKER ENGINE - COMMUNITY" and did sudo apt-get install docker-ce docker-ce-cli containerd.io everything was working fine until it reached this part:

Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /lib/systemd/system/docker.service.
Created symlink /etc/systemd/system/sockets.target.wants/docker.socket → /lib/systemd/system/docker.socket.
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xe" for details.
invoke-rc.d: initscript docker, action "start" failed.

would anyone be able to help me troubleshoot this?

Found the solution. After a system reboot docker is working
