If you want to connect to Citrix Servers remotely via ICA Protocol, then you must install Citrix ICA Client on your computer. In Windows, it’s very easy to do but not for Linux systems, including Ubuntu. This tutorial will show you how install Citrix Client in Ubuntu Lucid or Maverick with ease.

Getting started:

To get started download Citrix Client .deb package for Linux from here.

Choose ‘Open with GDebi Package Installer (default)’

Then click ‘Install Package’

When prompted, during the installation, accept the EULA and click Forward.

After installing, close out and try to connect to your Citrix Server.

If you get ‘Thawte Certificate’ error shown below, then continue below.

Download and extract Thawte Certificate from here.  After extracting the folder, select the right certificate for your server and copy.

Then press Alt-F2 on your keyboard and type the command below then click Run:

gksu nautilus /usr/lib/ICAClient/keystore/cacerts

Paste the file in here.

Now try again and this time it should work.
