How to make the keyboard shortcuts like macOS on Ubuntu?

Solution 1:

Ubuntu 20.04, June 2020

After spending an insane amount of time trying to figure out how to get MacOS-like shortcuts working on Ubuntu, I've found kinto. Just follow the instructions, it worked perfectly on 20.04 for me using an Apple aluminum keyboard. CMD-C/V copies & pastes everywhere and CTRL-C etc. work in the terminal.
