 Certificate error when using Citrix Receiver.

 By default, Citrix Receiver only trusts a few root CA certificates, which causes connections to many Citrix servers to fail with an SSL error.

+**NOTE:** Some systems may require this instead:
+<code bash>
+ln -sf /etc/ssl/certs/* /opt/Citrix/ICAClient/keystore/cacerts/
+</code>
+Since versions 13.1, Citrix needs the certificates in separate files. You need to run the following commands as root:
+<code bash>
+cd /opt/Citrix/ICAClient/keystore/cacerts/
+cp /etc/ca-certificates/extracted/tls-ca-bundle.pem .
+awk 'BEGIN {c=0;} /BEGIN CERT/{c++} { print > "cert." c ".pem"}' < tls-ca-bundle.pem
