Hi, im having a problem with the NAM installer on linux, i try to run the jar file with Java command and even chmod +x th  file to run it but it gives an exception that i'll paste here below:
OS: "Debian GNU/Linux 10 (buster)" Java :  openjdk version "11.0.9.1" 2020-11-04
OpenJDK Runtime Environment (build 11.0.9.1+1-post-Debian-1deb10u2)
OpenJDK 64-Bit Server VM (build 11.0.9.1+1-post-Debian-1deb10u2, mixed mode, sharing)
