Unimus forum

Please excuse my ignorance if this is a simple thing. When I try to run java -jar Unimus.jar I get the following error: (Any suggestions would be appreciated)

What is your JRE version?

This error indicates your JRE is too old to run Unimus.
(Unimus requires JRE 1.8.0_50 or newer)

Thanks. That fixed it.

We are running in Debian. I don't do a lot of server stuff. Usually I'm installing packages that install their own start up scripts and everything. Do you have and suggestions on the best way to make this installation persistent/ (ie start up automatically and keep settings)

.deb packages are planned before release, just not available yet.
(also an apt repo with those .deb packages is planned)

UPDATE:
We have an installer which will help install in Ubuntu/Debian:
