Citrix Receiver and SSL Error 61 on Linux

Are you getting an error like this?

You have chosen not to trust "Go Daddy Secure Certificate Authority", the issuer of the server's security certificate (SSL error 61).

The solution is to download the appropriate root certificates (Godaddy’s are here) and save them to /usr/lib/ICAClient/keystore/cacerts.

                      wget -P /usr/lib/ICAClient/keystore/cacerts --no-check-certificate https://certs.godaddy.com/repository/gd-class2-root.crt https://certs.godaddy.com/repository/gd_intermediate.crt https://certs.godaddy.com/repository/gd_cross_intermediate.crt
                      

Edit: One of my co-workers has a script that will do this for you.
