The installation of Citrix Workspace under Linux is unfortunately not quite as easy as under Windows, but with a few adjustments it works perfectly.

This installation guide was created for a Debian-based system, but the installation process should be similar on RHEL and other systems.

Downloading Citrix Workspace

Download the Citrix Workstation package(s) for your distribution here.

Installing Citrix Workspace

Install the downloaded package(s) on your system.

Please note that the installation process may look different on non-Debian systems.

sudo apt install icaclient_*_amd64.deb -y

Starting Citrix Workspace

You can now start Citrix Workspace app via the start menu or the search function of your system.

You will then be prompted with a login screen. There, you can enter the login details provided by your company.

Trusting a CA certificate (optional)

SSL Error 61: You have not chosen to trust ‘Certificate Authority’…

If the login fails, you will most likely have to trust your company’s CA certificate. If your company provided you with a certificate, you can copy it to the following path. Make sure that the CA certificate file belongs to the root user and the root group and that the file permissions are -rw-r–r– or 644.


If not, you can simply create a link to the Firefox keystore.

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

Middle mouse click does not work in Citrix Workspace

The middle mouse click does not work on certain virtual systems. This can be easily fixed in the Citrix configuration file.

To do this, you have to open the file /opt/Citrix/ICAClient/config/All_Regions.ini in your favorite file editor.

sudo nano /opt/Citrix/ICAClient/config/All_Regions.ini

Search for MouseSendsControlV=* and replace * with false.

Save the file and restart your Citrix session.
