i tried a lot of time to enter the command docker ps -a in terminal i am getting this error this error:

my Operating system: "ubuntu 22.04"

Cannot connect to the Docker daemon at unix:///home/ali/.docker/desktop/docker.sock. Is the docker daemon running?

but when i try this command again with root access the command works fine but the command not working without root access

This is the correct behaviour.

If you don't want to type sudo docker all the time you can either add your user to the docker group but I don't recommend that (it is not secure) or you can create an alias like alias docker='sudo docker'. Your user need to be in the sudoers list, obviously.
