Fix Citrix Connection Refused in Ubuntu 18.10
Fix Citrix Connection Refused
This fixes the Citrix 0.0.0.0 Shared Desktop connection refused issue:
sudo mv cacerts cacerts.old
ln -s /etc/ssl/certs cacerts
sudo ln -s /etc/ssl/certs cacerts
It does this by using up to date certificates rather than seemingly old ones included with the Citrix receiver installation on Linux.
