Some readers contacted me about the possibility to write an article about things to do after a

fresh installation ofUbuntu 12.04 Precise Pangolin. In fact, there are many things to do aftera new installation of Ubuntu 12.04, but in this guide I will try to give you what is important. If

you think we have missed something interesting for Ubuntu 12.04, please mention it in thecomment form given below.

1. Updating Your Repositories

The first thing to do is to configure Ubuntu to download packages from main Ubuntu servers

instead of location-based servers to avoid the notorious 404 error when installing packagesfrom the terminal using the "apt-get install" command. To do this, start the terminal (Ctrl+Alt+T) and run this command:

sudo software-properties-gtk

Make sure all options under "Downloadable from the internet" are checked on, then select Download from: Mainserver:

In the same window, open the "Other Software" tab and check on all unticked sources (Canonical, Independent, etc.):
