I was getting SSL Error 61 when I was using the Citrix ICA Client:
Contact your help desk with the following information: You have not chosen to trust "VeriSign Class 3 Secure Server CA - G3", the issuer of the server's security certificate (SSL error 61).
To fix it your need to copy the certificate files from Firefox. I know that sounds weird but it works.
sudo ln -s /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts/ sudo c_rehash /opt/Citrix/ICAClient/keystore/cacerts/
