I am new to Docker. Installed it successfully on my Ubuntu server. Then pulled lscr.io/linuxserver/sabnzbd:latest. That seemed OK but I can’t run it.

roel@ubuntu:~$ sudo docker pull lscr.io/linuxserver/sabnzbd:latest

There are multiple problems here.

  1. You build the image using sudo, so you have access to the docker socket, but then you try to run the container without sudo and you don’t have access to the socket. Your user is probably not in the “docker” group.
  2. You also have a “no such file or directory” error message which indicates that the line break is wrong before the image name. Maybe a space after the backslash so the image name is executed as a command in the shell instead of using it as a parameter of the docker command.

Thank you, that was fast! I try to learn as fast as you answered, making good progresss. This is really interesting.
