Are you experiencing an Error 61 when attempting to use the Citrix Receiver application in Linux?

The full text of this error reads as follows:

You have not chosen to trust "[Certificate Name Here]", the issuer of the server's security certificate (SSL error 61)

This error has to do with CA certificates not being trusted. Luckily there is an easy fix.

For this tutorial you will need Firefox installed. Your paths may be different, check your paths and adjust accordingly.

STEP 1
Open a terminal and execute the following command to copy the CA certificates from Firefox to the Citrix Receiver application directory:

sudo cp /usr/shares/ca-certificates/mozilla/*.* /opt/Citrix/ICAClient/keystore/cacerts/

STEP 2
Launch your Citrix application
