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

I am using ubuntu 22.04 version.

Answer 1

In my case:

• I had installed docker desktop by apt in ubuntu20.04 before, but removed it later.
• And when I try to check sudo docker images today there is the same issue.
• Restarting docker, chown socket and some other strange ways don't work.
• Suddenly I discover that there is no such socket file in docker/desktop/, but in the default location /var/run. Then trying to restore docker default context by docker context use default makes everything come back to normal.

So I think that the remained docker-desktop context takes the responsibility.....

Answer 2

Yes indeed docker context use default this command solved my issue
