Hello, please bear with me as first post, not a total newbie still having to learn rapidly,
I have just installed Fedora 28 on my Desktop PC, and installed Citrix Workspace 1810 (release) for Linux RHEL. No errors during installation.
When I try to log in from home onto my employers corporate Virtual Estate (Citrix Netscaler)
I get the error message::
Can not connect to 0.0.0.2 - no such file or directory.

I know its not the Remote End as have connected from Laptop (dual boot Windows and Ubuntu)
Has any one come across this?
And wondering why latest release of Citrix for Linux should have this error?

regards
Hugh

So eventually got it sorted and for anyone struggling like me, these steps fixed it:
https://support.citrix.com/article/CTX231524
1.Click on the Lock left of https://... and choose "More Information"
2.Click on "View Certificate"
3.Change to the tab "Details"
4.Highlight your CA certificate in the Certificate Hierarchy field and click the "Export" button
5.Save the certificate (in X.509 Certificate (PEM) format) to your Desktop and give it the file extension .crt
6.Sudo copy the file to /opt/Citrix/ICAClient/keystore/cacerts and then execute command /opt/Citrix/ICAClient/util/ctx_rehash

Still wonder why I didn't have to do this previously.
