Citrix Receiver requires OpenMotif v2.3.1 or greater to use the Graphical User Interface.
The first step is to install OpenMotif 2.3.1. You can download OpenMotif from Launchpad. Once downloaded and installed, download Citrix Receiver. deb file.
Once downloaded, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, navigate to the folder where the file was downloaded (probably the Downloads folder), and run the command(s) below:
sudo dpkg -i <file_name>.deb
