I tried installing this on two different Ubuntu machines using their Ubuntu repo and it did not work. Worked fine on both Android and Ios. This is about what I expect from a java application - the java ecosystem is co convoluted and fragile that the only real options are Android, Ios, and Docker. I wish someone would write something like this in Go or Rust.
