Hello Linux Users.

In this brief tutorial I will show you how to install Adobe Reader on Ubuntu 13.04 Raring Ringtail.
Adobe Reader is not in the Cannonical repo (or at least not yet), so you have to download the source and install it with dpkg.
Let’s start:
Download Adobe Reader:
$ wget -c http://ardownload.adobe.com/pub/adobe/reader/unix/9.x/9.5.4/enu/AdbeR
Install Adobe Reader:
$ sudo dpkg -i AdbeRdr9*
Next, you have to make some configurations. Open the 98menuproxy file with your favourite text editor:
$ sudo gedit 98menuproxy
Paste this line in 98menuproxy:
export UBUNTU_MENUPROXY="acroread":$UBUNTU_MENUPROXY
Optional: To uninstall Adobe Reader, do this:
$ sudo apt-get purge adobereader-enu*
$ sudo apt-get autoremove
