So I've looked online and haven't found a clear explanation of the default Debian source list.Specially, what do main, updates. proposed-updates and security mean in the context of /etc/apt/sources.list?I can make assumption about what they mean, but I haven't found enough information to understand if I should, for instance, include updates when switching to testing. https://wiki.debian.org/SourcesList has some information, but not omits any information on updates or security.I am fairly new to Debian, and while I think I could just muddle through the distinctions here, I'd really like just a clear explanation of what is going on instead of just copy and pasting lines into /etc/apt/sources.list.
Explanation of the default Debian sources?
