I have Vanessa (Mint 21) on a VM, and i was playing with it installing different programs just for fun and curiosity.
I found a nice screenshot program, "Shutter" so i decided to use it on my 20.3 setup, then i found out it is not available in the software manager or via
So in their site @ shutter-project.org, there is the option to install it on Mint, from an "official PPA" link here: https://launchpad.net/~shutter/+archive/ubuntu/ppa
My question is about security, and also trying to learn how the software sources are managed in Mint.
After reading many posts here on the forum against setting up PPAs, i wonder if Vanessa is actually pulling the program from the same source so it is safe for me to setup this specific PPA, or ubuntu keeps its own copy in the ubuntu repos and that is where Vanessa pulls the software from?
What is the "line" between a safe and an unsafe PPA?
