The link from the install walkthrough takes me to the Docker site, where I find that the reason the stock Ubuntu Docker (which appears to be 1.13) complains in -compose is because Xibo wants Docker 2…
which appears to be commercial these days, and not FOSS anymore at all.
Am I missing something, or did I miss something?
Oh. The link defaults to EE, not CE.
Nevermind. :-}
Ok; different problem.
I’m following the instructions at:
and the step:
sudo apt-get install docker-ce
returns
jra@pano:/appl/downloads/xibo-docker-1.8.9$ sudo apt-get install docker-ce

Package docker-ce is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'docker-ce' has no installation candidate
Huh? 
Oh, are there really no packages built for 16.04LTS?
jra@pano:/appl/downloads/xibo-docker-1.8.9$ apt list -a docker-ce

Or are those docker version numbers somehow?
We have a complete guide for Ubuntu 16.04 here:
You’re sure your system is 64 bit, as Docker won’t work on 32 bit installs.
Oh bother. Yes, I’ll bet you cash the machine has a 32-bit install. Oops. I know I had a good reason for that when I did it, but I don’t remember what it is anymore.
Nice catch, thanks.
