What is Citrix Receiver?

Citrix Receiver is a piece of software that allows access to XenDesktop and XenApp installations. This means you can access remote computers from any web browser with Citrix installed.

Where can I get it?

Citrix Receiver can be downloaded from here: [1]. Remember to choose the relevant option (Linux in this case)

How do I install it?

• Navigate to the link above and choose either the 'latest' or 'earlier' versions as desired
• Choose the relevant Tarball Package for your computers' architecture (x86_64) or (x86) and download it
• Accept the End User Licence Agreement if you are happy with it - it is very short
• Save the file to a suitable location on your computer (~/Downloads)
• In a terminal navigate to where you downloaded the tarball to and untar the downloaded file:

tar -xvzf linuxx64-13.3.0.344519.tar.gz

What problems may I have?

Receiver not starting

This behaviour can be modified in Firefox by going to:

Tools>Add-ons>Plugins>Citrix Receiver for Linux

and choosing 'Always activate'

Missing certificates

Citrix has only a few certificates in the default install. You can add the ones for the site you are logging into by:

• Going to the login page for your target site and clicking the padlock icon on the left of the address bar
• Clicking 'More information'
• Clicking 'View Certificate'
• Clicking the 'Details' tab
• Choosing the top level certificate field
• Clicking 'Export'
• Copying the .crt file to the Citrix keystore folder:

# cp *.crt /opt/Citrix/ICAClient/keystore/cacerts

• Linking the new certificates in Firefox:

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

# c_rehash /opt/Citrix/ICAClient/keystore/cacerts/

Citrix crashes

This is caused by the GTK theme in KDE being set to 'Oxygen'. Change this in:

system settings > application appearance > GTK > GTK Themes

Where can I find additional information?

The Ubuntu Community Wiki has an excellent guide to this software: [2]
