If for whatever reason you need to install Adobe Photoshop CS4 in Ubuntu, here’s the easy way of doing this:
1. Install Wine:
You can install Wine from the official Ubuntu repositories however from my experience I can say the Wine version in the Wine PPA, even though is not officially “stable” works very good. So to add the Wine PPA and install Wine, use the following commands:
sudo add-apt-repository ppa:ubuntu-wine/ppa sudo apt-get update sudo apt-get install wine1.4
2. Add the PlayOnLinux repository and install the app:
wget -q "http://deb.playonlinux.com/public.gpg" -O - | sudo apt-key add - sudo wget http://deb.playonlinux.com/playonlinux_$(lsb_release -cs).list -O /etc/apt/sources.list.d/playonlinux.list sudo apt-get update sudo apt-get install playonlinux
3. Now let’s install Photoshop in Ubuntu: open PlayOnLinux (Applications > Games > PlayOnLinux), click “Install” and search for Photoshop CS4, select it and click “Apply” – this will install all the required .dlls for installing and using Photoshop under Wine:
Once selected, click “Forward” and the Photoshop setup window should be displayed – now simply install Photoshop like on Windows. When finished, PlayOnLinux will let you add a shortcut in the menu (or on your desktop) which you can use to run Photoshop CS4.
