The ''security updates'' are set to auto update. I usually install the ''recommended updates'' when they are released.Today I saw a distribution update via update manager for Skype.Is it always better to install the distribution updates as soon as possible or is it better to not touch a program if it is working properly.
Do install the Skype, its an improved version, the camera now works without ld_preload command and its a pleasure to see it back in Ubuntu repos.
i usually update everything if there is little bug in some application i wait till next update try to repair, put it on forums if i dont understand 99% its resolves, uninstall and reinstall or roll back in my fedora wonder if same roll back feature works in ubuntu as well i never tried
Synaptic will show installed version difference and you can force select another version of same software.
