Tough task: Everytime I try to stop or kill a running container, I get permission denied as an error response from Daemon.
I just started learning how to use docker by using a Ubuntu18.04 VM. I was running a container for the first time. I was not able to stop it but at least it was running. Now, after I tried to run another image "furtuas/daisitory:image_available_first_ms", everything got worse. Two containers are running, I can't stop non of them. I tried to restart docker but the containers are still running with the difference that localhost is not working anymore. Maybe it happened bc I ran on the same host like the one before
I am not familiar with docker, ubuntu, terminal etc. I would appreciate detailed answers for beginners

Please help.
$ docker ps -a

After logout the VM, still the same response:
$ docker stop 66c6c49a95f4
Error response from daemon: cannot stop container: 66c6c49a95f4: Cannot kill container 66c6c49a95f499abeb62b1c02e7e9b8ce1739709bb2140ba7b1a61094a9d16f7: unknown error after kill: runc did not terminate sucessfully: container_linux.go:387: signaling init process caused "permission denied"

I solved it but I am not sure why. I think I solved it by restarting the VM and restart docker with these commands
Flush changes: $ sudo systemctl daemon-reload
