I installed a PPA for the very first time, according to instructions here. I achieved my goal (needed to install an application by the name Solaar), and now I wonder if I can uninstall the PPA without affecting the installed software (Solaar).
I manually added the PPA through Software Center > edit > Software Sources. And now there are three entries saved/logged.
What I am basically asking is; after the desired install is done, is the PPA disposable?
Yes. You can remove the PPA after you are done installing.
However, you will no longer receive updates to software.
PPAs are "software repositories". You get software from them. The software doesn't need it.
Think of your program as a bottle of milk. The PPA is the store. When you buy the milk, the milk (nor you) no longer needs the store. You can (if you want) never go to that store again. However, if the store recalls the milk, you can go back and get new milk.
