Overview

There are a number of software packages maintained for compatibility with
Ubuntu that can be easily installed on your pairCloud® server. The archive
of packages can be viewed and searched at:

http://packages.ubuntu.com/

One method for installing packages is via APT with the apt-get command.
The full usage information for that can viewed at:

To install a package, first, make sure that the package index on the server
is up to date by running:

sudo apt-get update

Next, the package itself can be installed with the following, replacing
PACKAGE with the official name of the package as seen in the Ubuntu package
archive:

sudo apt-get install PACKAGE
