====== Problems with CA or other certs ======
Place all certs that you need in /opt/Citrix/ICAClient/keystore/cacerts/ and do a rehash afterwards
<code>
/opt/Citrix/ICAClient/util/ctx_rehash
</code>


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

====== Strange Problems after Update ======
Do no Updates!
I always remove the RPM and the /opt/Citrix folder and the config in my home-dir.
<code>
rm -rf ~/.ICAClient
</code>
