I have recently installed the synaptic package manager and there are various options related to the universe and the multiverse in it. what exactly are they and how do you you use the Synaptic package manager with them
Here is a screenshot of the 'Software & Updates' window (part of Ubuntu's default software setup):
- The main repository is the main software for Ubuntu, and is officially supported by Canonical (Ubuntu's parent company)
- Universe has open-source programs that can be used in Ubuntu, supported by the Ubuntu & linux community.
- Multiverse includes video codecs, encrypted DVD streamers etc, which may not be open-source, and/or may cause legal problems.
- Restricted - Closed-source drivers
You can also add other repositories/PPAs to download packages from (though please check if you can trust the source of the compiled software!!). Sometimes these are included in packages for updating them - e.g. for Google Chrome, Spotify.
