I have a VPS with Ubuntu Server 12.04 and I want maximal stability of my server, which's main purpose is a webserver.
What are difference between
Upgrade? I can't understand difference. As I understand
Upgrade is upgrading version of package of some software product and if this upgraded software have, for example, some API change and my code can become incompatible with that update I will run into problems. But since this is only small version change compared to big version change using
dist-upgrade most times those upgrades will be compatible with my code. Do I understand it right?
Second small question is
sudo apt-get update is the same as if I run
sudo aptitude and install all Security updates? I love
aptitude, it is something like Windows Updates, that's why I choose Ubuntu Server.
