It appears that you are using Ubuntu Linux. &nbsp;Which is a variant of Debian Linux. &nbsp;Hence you trying to install Debian's packages.<br />
<br />
In the link that you have given, packages are divided into two groups-- one for 64 bit servers, and the other one for common 32 bit Intel kind of machine architectures.<br />
<br />
Based on what kind of architecture you have, you should install all the packages in the group to make sure it work correctly. &nbsp;Most of the packages appear to be libraries to provide the functionality to the main package. &nbsp;If your current system has 'good enough' packages on it right now, you will not have to install more packages that are not in this list. &nbsp;Otherwise you might have to get even more.

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux.
