How to install photoshop cs6?

Here are your options.

1. Use VirtualBox or something similar to actually create a virtual computer that you run Windows in.
2. Use Wine to run CreativeSuite. Wine is a way to run Windows software on Linux, but it's hit-or-miss.
3. Use CrossOvier to run CreativeSuite. CrossOver is based on Wine, but commercially supported. Unfortunately, it doesn't look like they have much in the way of CS6, though earlier versions might be better supported.

Bottom line is, you can't directly run CS6 on Linux. VirtualBox will probably be the most reliable method, but that isn't really using Linux; it's using Windows, inside Linux.

Using wine, you get all the details / problems over here

You can install Photoshop CS6 on Ubuntu using WINE1.5 or above. I followed this guide and Im using Photoshop CS6 on my ubuntu 13.04
