Tested only on Ubuntu 18.04 and KDE Neon User Edition (based on Ubuntu 18.04).
will probably work on other newer versions, with no changes, or with few changes in non-python dependencies (apt-get packages)
NOTE: Don't create a .sh file and run it all at once. It will not work. Copy, paste, and execute each command below manually. :-)
