Tried to uninstall docker and reinstalled it but it raises the same error is the docker daemon running can someone help me here.

Answer 1

There is a service that docker requires that is not running, thus, systemd won't launch docker.

Try launching journalctl -f (without -u) to see all unit logs, then start docker and read carefully the log, you will probably see some other units trying to start and failing.
