@Paramite Not really. Doing the commands you mentioned only syncs the packages with the latest patch of the major release.

For example, Let's say you have installed program A version 1.6. 1.6.1 comes out, which is a small patch to 1.6. But 1.7 comes out and is a bigger feature update.

In the name of stability, you would only get 1.6.1 until A. You build it from source B. You get it from a PPA or C. You upgrade Ubuntu versions, which updates the package lists to include the package for version 1.7.

@orkhanfarmanli They also include packages of the newest versions of applications.
