I'm right-clicking the minecraft.jar file and going under the Properties tab and there is no checkbox that allows the file to be executable.

Neither the Open With nor command options are working either. Any ideas?

JAR files are not executable in the same way as shell scripts and programs are. Rather, you need java to run them.

Check to see if you have Java Installed

Run the following:

java -version

If you get something like this, you have it installed and you can skip the Installation step. If not, continue with the Installation Step. "java -version" terminal output

Installation (If you don't have Java Installed)

sudo apt-get update
sudo apt-get install openjdk-8-jre

The Fun Part :)

Now, after all that hard work, now you can run it! :)

Run:

java -jar filename

where filename is the name of the JAR file.

If you have any questions / comments, please comment on this answer. :) Thanks!

Use the minecraft-installer:

sudo add-apt-repository ppa:minecraft-installer-peeps/minecraft-installer
sudo apt-get update
sudo apt-get install minecraft-installer

Once installed, run Minecraft from the menu / Dash, login with your Minecraft account and the installation should start automatically.
