How can I run .jar files?
I need to install a government program on my mom's laptop, it's running Mint 22.3, but it's like no matter what I do it just does not want to open.
I set the display thing to X11, and installed the Java softwares (including runtime)
But both the terminal method and the GUI method don't open the program
When I tried opening throught terminal, I got this:
"No 11X DISPLAY variable was set,
or no headless library support library was found,
but this program program perform an operation which requires it."
