Linux Citrix Receiver generates the following SSL error when trying to launch a published application or desktop:
“The security certificate “aaa.bbb.ccc.com” could not be validated. SSL provider code: 20, SSL error 86”.
During the installation process, a certificate repository is created below the Linux Receiver’s installation folder (/<client install directory>/keystore/cacerts). The copies of the security certificate and up-to-date root CA must be placed in the directory.
This error may occur due to a missing or an outdated root certificate on the client device.
