Ubuntu 15.10 - Citrix Receiver - SSL error 61

Solution 1

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

Solution 2

Follow the steps from Citrix Workspace App for Linux: How to trust a CA certificate?

I'm using Ubuntu 16.04.1, Firefox 50 and Citrix Receiver 13.4.

@thorsten-niehues solution didn't work for me unfortunately.

To solve the problem, I had to copy the .crt file to /opt/Citrix/ICAClient/keystore/cacerts

I was then able to connect to Citrix with Firefox and with Chrome without any problem.
