Problems with CA or other certs

Place all certs that you need in /opt/Citrix/ICAClient/keystore/cacerts/ and do a rehash afterwards

/opt/Citrix/ICAClient/util/ctx_rehash

SSL Problem / missing Libary

You may face some issues with an libary problem. Please check if the path to the lib and the lib itself are on your system.

sed -i 's;Exec=/opt/Citrix;Exec=env LD_PRELOAD="/lib64/libcrypto.so.1.0.2o" /opt/Citrix;g' /opt/Citrix/ICAClient/desktop*.desktop

Do no Updates! I always remove the RPM and the /opt/Citrix folder and the config in my home-dir.

rm -rf ~/.ICAClient
