You know, it’s unfortunate but it would seem that Adobe has stopped compiling Adobe Reader for Linux / Unix systems :(

The last version you can get that will install on Linux / Unix is here:  ftp://ftp.adobe.com/pub/adobe/reader/unix/9.x/9.5.4/enu/

Download the .deb package, right click on it then click “Open with Ubuntu Software Centre” and yes, that’s “Centre” not “Center” – that happens to be a difference in spelling between the American English and British English or English from outside of the United States.  In the town next to the one I live in and where I have an office the street is called “West Centre Avenue” but before I noticed that spelling I hadn’t noticed it in Ubuntu even though I use the English version of Ubuntu there’s still that “quirk”…have you noticed it said “Centre”?  :)

Note:  There are other PDF readers like xPDF but I’m partial to Adobe’s Reader
