Synaptic and the Repositories

Translated from German by tschommer

Since I often read that every once in a while a user wants to enable several repositories, 
I want to stress once again:

Please activate only one repository!

All servers are mirrors which are not all synchronized at the same time. In 99% of the 
time this will lead to problems.
So please, only use one server that is close to you.

Synaptic is either in the panel or can be found in the menu under Applications > Software Center > Package Manager. You need the ROOT password in order to run Synaptic.
