Hey, just a suggestion, to avoid sudo: add-apt-repository: command not found
the first line could be updated to sudo apt-get install software-properties-common python-software-properties
as in https://gist.github.com/DevipriyaSarkar/5b67f39eaead3209809aca80c6fd53a7
Thanks 👍
Unattended installation, anyone?
