Citrix Receiver on Ubuntu 18.04

There’s a Debian package available for Citrix Receiver, so in principle this task should be trivial.

It’s not.

Simply installing the package leaves you with a SSL error whenever you try to connect to a Citrix resource. You need to jump through a couple of extra hoops to get it actually working.

Installing the Package

Download the package from here (scroll down to the “Debian Packages” section).

Install it.

$ sudo dpkg -i icaclient_13.10.0.20_amd64.deb

Now you need to sort out the SSL certificates.

Sorting the Certificates

Link in the certificates (these should already be resident somewhere on your machine).

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

Create a hash for each certificate.

$ sudo c_rehash /opt/Citrix/ICAClient/keystore/cacerts/

And you are ready to roll! Connect to your Citrix resources. Enjoy.
