# It's most likely because Citrix Receiver only include a few root certs
# and the server you are connecting to is not using one of these.
# To map more root certs to Citrix Receiver in Ubuntu do this:
sudo ln -s /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts/
sudo c_rehash /opt/Citrix/ICAClient/keystore/cacerts/
