How do I setup Virtual Lab on Linux

Installing the Citrix Receiver

Note: Linux is not a supported operating system for Virtual Lab and it is recommended that you use a Windows or Mac to access Virtual Lab from your computer. However, Citrix does provide a Receiver for Linux and we have been able to get it working on several versions.

Go to the following site to get download and install the latest version of the Citrix Receiver:

Once downloaded, open up the Receiver and under “Add Account”, enter (Note: If prompted for “Domain”, enter “”).

Then, you should be able to log in with your Onyen and Password and run applications.

SSL Error 61

We have seen users commonly get the following error message when configuring Citrix Receiver for Virtual Lab:

You have not chosen to trust “AddTrust External CA Root”, the issuer of the server’s security certificate (SSL error 61)

This occurs because Citrix Receiver does not have access to the certificate for our CA provider. You can typically fix this by giving Citrix Receiver access to or copying certificates from the Mozilla certificate store as they do have the proper certificate. Here is a link that details how to make this change:

Make sure to modify the instructions to point to your correct installation directory for Citrix Receiver.

After performing those steps, then you should be able to configure Virtual Lab and run applications.
