For other Linux distributions that don't support PPA, you can get the Inkporter script via this page: https://github.com/raniaamina/inkporter/releases/tag/v2.3.1-linux. Extract the zip file and put the whole file into /usr/local/bin/ and make sure you have set execute permissions on the file to allow it to execute as a program (sudo chmod +x FILENAME).
