Cannot connect ot Docker docker daemon at unix:///var/run/docker.sock


I can’t install Niagara 4 Port on Dell edge gateway500 because docker daemon is not running.


It would appear docker is not running on your system for some reason.
I would recommend doing 3 things.

  1. Uninstall the current version of docker

sudo snap remove docker

  1. Update all snaps (requires internet connection) for your system and restart.

Update everything, could take a few minutes depending on connection speed:

sudo snap refresh

Restart the system:

sudo shutdown -r now

  1. Run the installer again and when selecting the option to install docker, choose install from the internet.

If the next step in the installer process still fails to access docker. Restart the system again so that it has a clean boot with docker installed. This should get you up and running to finish the installation process.


Thanks a lot. I got it and installed on my Dell.
