mbbackus It is like that since a couple of days. Bad news. Considering the 8+ year long, 1100 post support thread https://moodle.org/mod/forum/discuss.php?d=154988, I don't think it is lost.
As far as the installation is concerned, ./install-vpl-sh as root on MoodleBox did almost everything, including fetching hundreds of megabytes of Debian packages! My post in the VPL thread was on how to run them together in the same box and make it reachable through port forwarding.
If you urgently need the VPL package, I can give you a copy, it is only 144 kB. Send me a PM through moodle.org.
