Identify which user added ppas

cn flag

I am responsible for a system, which someone else had setup. Sadly we just started documentation after I took the honor. We had an issue with old bionic packages since we dist-upgraded to 20.04 and solved it, but we are still messing with a few ppa's which I in first place need to figure out what they provide and in second place who installed them.

Is it possible to figure this out?

The Launchpad page for each PPA contains a 'description' field. Alternately, you can use `apt redepends <package_name>` and `apt-cache policy <package_name>` to untangle the dependencies...if you have a package name to start the process. Or you can list the PPAs in your question.

1. Yes, list the PPAs. Someone here should be able to identify it; 2. It may be difficult to know who added them into your computer system, but it needs elevated permissions, so it must be someone who had 'sudo' access.

1. Identifiying which is not the problem for me. 2. part is my trouble and yes I now they are sudoers, but there was alot going on in the past with the system and I wanted to know which of them installed the ppa. Two of the sudoers are hard to contact at the moment so I am looking for a way to understand what they installed to maybe figuring out why they installed the ppa and if I can remove them.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
