This question already has an answer here:

I am going to install Ubuntu 12.04, and I wonder if I should trust/run the .sh script proposed on this site: Things to do after Installing Ubuntu 12.04 Precise Pangolin.

By the way, do I need to anything in particular after installing Ubuntu?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

As a rule of thumb you should never run a script you don't understand or copy and paste something directly from an untrusted web page into a shell, especially a root shell! It could be something entirely different from what appears on the web page and therefore execute arbitrary command.… – David Foerster Dec 6 '13 at 20:01

In fact you will learn a lot more if you do the steps one-by-one, rather than just run the .sh script. This also has the advantage that you can check whether the proposed software is still being maintained. To give but one example: today one would no longer advise to install Firestarter.

Also, as a general rule you should not trust the internet.

The script was originally written of elementary OS Luna, and Ubuntu 12.04. If you're running 14.04, some of those steps are downright harmful, and others simply unnecessary. Examples being:


  • Using precise repositories in/etc/apt/sources.list - use trusty if you have to muck around in there. Or the Software Sources GUI.
  • Deleting the backup of the sources.list (what sort of guide does that?)


  • Adding PPAs for GIMP, GNOME3 and VLC. All three are in very good shape in Ubuntu 14.04, with no reason for an average user to go gunning after PPAs.
  • Adding PPAs for Java. Java 7 is available for Ubuntu 14.04.
  • Getting libdvdcss from the VLC repository (see this answer).
  • Installing flashplugin-installer - I suggest adobe-flashplugin instead, which comes as a single package instead of downloading extra stuff from the internet.

Lastly, if you do install Google Chrome from the command line using the commands from that page, be sure to run sudo apt-get install -f after.
