Hi All,

I'm still having installation problems with Docker. I followed the 
Digital Ocean instructions for Debian 10 to the letter. Everything went 
fine until I tried to run the test case. I got the following:

I suspect that something might be wrong with the /etc/apt/daemon.json 
file but am not sure what.

My installation doesn't seem to be very stable. I'm using the free 
community edition if that helps. Any help will be sincerely appreciated.

Running dockerd produced the following:

On my system the /var/docker directory doesn't exist. Further, 
server.pem doesn't exist anywhere on my system. Now what?

Looks like you need to generate that file (1).

But in your ``daemon.json`` you explicitly asked for TLS and even provided
a path to these files.
(to enable TLS one needs a certificate (with public key) and private key
for it)

Let's see if docker works without this file.

# mv /etc/docker/daemon.json /etc/docker/daemon.json.back
# dockerd

if it works, start it with ``systemd`` and see if it works

 From my little experience, the default docker-ce installation comes 
without daemon.json file. Try to remove it and see if docker comes up.

It also doesn't look like Debian related issue tbh, since it is a third 
party package.

I reinstalled using the docker.com instructions and it works. I also 
installed Portainer. It also works. I appreciate all of the help. Now 
all I have to do is learn to use it.

Thanks again.
