Sometimes, you will not be able to open PDF documents or they will be displayed incorrectly or features - like filling out forms will not work. In this case download Acrobat Reader from http://www.adobe.com/products/reader.html. Then open a console and install it like this:

tweedleburg:~ # chmod 777 AdbeRdr9.4.2-1_i486linux_enu.bin
tweedleburg:~ # ./AdbeRdr9.4.2-1_i486linux_enu.bin 

Extracting files, please wait. (This may take a while depending on the configuration of your machine)

This installation requires 145 MB of free disk space.
