I like using apt-get install for my packages. However, I discovered that the repositories for apt-get is rarely updated after release. For example, when trying to install nodejs and npm today, I discovered that the repository still had version 0.10.29 and 1.3 respectively, while in reality they are at version 5.3 and 3.5.2 at the moment of this post.
So I'm wondering if there are any repositories for apt-get that are constantly updated with the latest stable release of packages? If yes, how do I set up apt-get to use those repositories? If no, are there other package managers/linux distributions that would suit my purposes better?
