Question about terminal

Wow, I did not know about Synaptic Package Manager.
I was just talking about where/how to install apps here Where to install apps not available in the software store? Home? /usr/local? other?

What would you recommend to do when searching to install new apps ?

  1. First checking with the Software (gnome-software) ?
  2. If no available, using the Synaptice-pkexec ?
  3. Finally, using other means to install the app.
