The Citrix ICA Client (Citrix Receiver) allows access to remote Windows sessions that run on a Citrix server.

These instructions are for current/recent Ubuntu/ICA versions. For historical reference, instructions for older Ubuntu/ICA versions are at CitrixICAClientHowToOlderVersions.

If you are considering deployment of the Receiver in your workplace (as opposed to installation on just your machine), have a look at the Citrix Receiver deployment how-to in the Ubuntu for the Enterprise wiki.


Citrix Receiver 13.1 on Ubuntu 14.04

1. (64-bit only) Alternative install procedure that can be added to a deployment bash script

http://mark911.wordpress.com/2014/06/27/how-to-install-citrix-receiver-icaclient-in-ubuntu-14-04-lts-64-bit-tested-and-working-using-mozilla-firefox/

2. (64-bit only) Enable i386 Multiarch

Even the Citrix Receiver for 64-bit systems has a lot of dependencies on packages from the i386 architecture. If you are using 64-bit Ubuntu and have not already configured i386 multiarch, you must configure it by running:

sudo dpkg --add-architecture i386
sudo apt-get update

N.B. The download link currently directs you to receiver 13.2 rather than 13.1 and the 64-bit deb no longer has i386 architecture dependencies.

3. Download the Citrix Receiver for Linux .deb package

4. Install the downloaded package(s) and dependencies

In case your Ubuntu Software Center didn't install the Citrix receiver, so you had to download it, now install it as follows:

sudo dpkg -i ~/Downloads/icaclient_*.deb ctxusb_*.deb
sudo apt-get -f install  # Install dependencies and finish configuring the package(s)

5. Add more SSL certificates

By default, Citrix Receiver only trusts a few root CA certificates, which causes connections to many Citrix servers to fail with an SSL error. The 'ca-certificates' package (already installed on most Ubuntu systems) provides additional CA certificates in /usr/share/ca-certificates/mozilla/ that can be conveniently added to Citrix Receiver to avoid these errors:

sudo ln -s /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts/
sudo c_rehash /opt/Citrix/ICAClient/keystore/cacerts/

6. Configure Citrix Receiver

Run:

/opt/Citrix/ICAClient/util/configmgr &

To map drives (to allow access to files on your local Ubuntu machine via a share drive in the remote Windows session), see the "File Access" tab.

7. (64-bit only) Fix Firefox plugin installation

Run:

sudo rm -f /usr/lib/mozilla/plugins/npwrapper.npica.so /usr/lib/firefox/plugins/npwrapper.npica.so
sudo rm -f /usr/lib/mozilla/plugins/npica.so
sudo ln -s /opt/Citrix/ICAClient/npica.so /usr/lib/mozilla/plugins/npica.so
sudo ln -s /opt/Citrix/ICAClient/npica.so /usr/lib/firefox-addons/plugins/npica.so

Starting with Citrix Receiver 13.1, the 64-bit version of Citrix Receiver switched from a 32-bit plugin (using nspluginwrapper to allow it to run within a 64-bit browser) to a native 64-bit plugin. However, the install script still configures the plugin to run within nspluginwrapper, which doesn't work with a 64-bit plugin. The above will reconfigure the plugin to run without nspluginwrapper.

8. Configure Firefox

In Firefox, go to Tools -> Add-ons -> Plugins, and make sure the "Citrix Receiver for Linux" plugin is set to "Always Activate".

Starting in Firefox 32, plugins are set to "Ask to Activate" by default, but for some reason the activation prompt is never displayed for the Citrix Receiver plugin, so the plugin will not work unless it is set to "Always Activate".

9. Configure Chrome/Chromium

To use Citrix Receiver in Chrome and/or Chromium, run:

xdg-mime default wfica.desktop application/x-ica


Known Issues / Workarounds

sudo perl -pi -e 's/ -ica/ --ica/g' /usr/share/applications/selfservice.desktop
