Citrix SSL Error Message

I installed Citrix according the Tutorial How to install Citrix Receiver icaclient in Ubuntu 14.04 LTS 64-bit The installation completed without any errors.

I also made sure that the certificates are there according to the CitrixXenAppPlugin – configure certificates:

Additionally I checked in Firefox if the certificates are known and even checked all marks (which where not checked before) (Under Settings -> Advanced -> Certificates):

Firefox Certificate settings

What am I missing?

OK thx to the hints from @sletarte here the solution:

  1. Place certificate to be trusted in /usr/local/share/ca-certificates
  2. Execute sudo update-ca-certificates
    You should see something line this:
    1 added, 0 removed; done. Running hooks in /etc/ca-certificates/update.d.... Adding debian:SymantecClass3SecureServerCA-G4.pem
  3. Use Google Chrome instead of Firefox
