how to open/run .jar files on ubuntuMATE?
I'm trying to run the file with openJDK option, and it gives me this error message:
"The file '/home/user/Downloads/WarUniverse.1.21.131.jar' is not marked as executable. If this was downloaded or copied from an untrusted source, it may be dangerous to run. For more details, read about the executable bit."
java -jar /home/user/Downloads/WarUniverse.1.21.131.jar

it's a MMORPG about spaceships, either way thank you
I read that if you install adoptopenjdk https://adoptopenjdk.net/ the game would work. Give it a try and let us know. You can switch java versions with sudo update-alternatives --config java
