Huge thanks for this tutorial/post
Available since 21 Sep 2023 and really very valuable.
As a friendly observation. Was mentioned about official and non-official PPA, it in the Official PPA vs unofficial PPA
section.
The reason of this post: currently is not clear explicitly how to detect if a PPA is official or not. I think it is missing, pls consider to cover that point.
Thanks for your understanding
p.d: As requested in other post. There is no a section in the forum to report suggestions/errors to any tutorial/post yet
