I am running it on a Debian derivative with no real problems and having completed the "Creating you first course" it shows great potential already. In fact it is useable, I think.
The only issue I have is that every time I reload the page in Iceweasel (Debian 's Firefox version) I get a popup with "Cannot GET /log_output.html" message.
I am going to try to use Adapt on a project I have had in mind for a couple of years. It is a very large project based on more than a thousand pages of lectures transcripts, so please someone stop me here if there is an issue with this. I would expect that it would take me 18 months or so.
I am retired and have had 45 years professional experience in software development, hence the reference to the old dog, and have plenty of time on my hands, so I hope that I may be able to contribute to the development as well. Just need hone my skills with Node.js, etc, first.
Anyway, wishing the best to the authors of this project and thanking them for open sourcing it! :)
