Even though this is well documented on the web, I’ll add some details on my experience running Citrix Workspace app (Citrix Receiver) via Ubuntu 18.04.
The explanation posted here worked for me at first, so I would start there. I would choose the Workspace App, which I believe is the updated version of the Citrix receiver.
One of my issues with method outlined in the first link involved the SSL certificates. A different approach to creating a link to the SSL certs (found here) is below if the previous code doesn’t work:
$ cd /opt/Citrix/ICAClient/keystore/
$ sudo rm -r cacerts
$ sudo ln -s /etc/ssl/certs cacerts
Here are some other things to try if the above didn’t work:
- Try a different browser and/or clear the browser’s history.
- Check for Citrix upgrades.
- If you are using dual authentication, try only using username and password (or visa versa).
- You may have success installing from a tarball.
Please leave any other ideas in the comments, as I’m sure things have changed.
