Re: [LINUX_Newbies] Downloading Problem

 

Stable is a term mostly associated with Debian. They run three levels of packaging: stable, testing and unstable. Everything starts out unstable and through time it moves towards testing and eventually is marked stable. All of that takes time which is why Debian stable is 2 - 3 years behind Ubuntu for the same application.

Ubuntu uses Debian unstable as its starting point. Other distributions based on Debian will run from Debian testing or Debian stable. It ll depends on who the distribution is geared towards. Debian stable is made to be rock solid. Ubuntu is not necessarily less stable than Debian. It runs its own testing and it has two levels of development, regular and LTS. When I refer to stability in Ubuntu I am mostly looking at the goals and the risks being taken by the developers.

When an LTS release is coming up Ubuntu makes fewer changes and takes less risk. A regular six month release, excluding the LTSes, is more inclined to take greater risks. LTS release goals are less ambitious and are less likely to cause problems. If they were planning a big change such as when they switched to Unity on an LTS cycle then they would try to phase in the change and to make accommodations for users. LTS is considered more stable because they want to make the user experience for enterprise better with fewer surprises. The same software channels are used for servers as for desktop.

Ubuntu also uses different package groups such as Main (official), Universe (community), Restricted (not open source), and Mulitverse (not free license, likely has an EULA to agree to). This just compounds the confusion, because users get it all from the same package manager. Most if has to do with internal controls and the developers interests. To be a Master of the Universe or MOTU (real title) one must be approved by Ubuntu and you must meet their terms and goals.

One for the stable crowd and one for the adventurous crowd.

What does adventure mean?
