~~Same here~~

Edit fixed it: Install jython properly and the plugin will be installed successfully:

wget https://repo1.maven.org/maven2/org/python/jython-installer/2.7.4/jython-installer-2.7.4.jar
java -jar jython-installer-2.7.4.jar

Expected output:

java -jar jython-installer-2.7.4.jar 
DEPRECATION: A future version of pip will drop support for Python 2.7.

Then go to Extension settings in Burp and add the "jython.jar" binary located at ~/jython2.7.4/. Now add the extension with Python extension type and the .py file from the repo, and you should be good to go
