So, you've upgraded Firefox on Ubuntu and Citrix no longer works, well do the following:
- uninstall Firefox
- install Firefox
- $ sudo rm -rf /opt/Citrix/ICAClient/keystore/cacerts_old
- reinstalled Citrix
- redo the Citrix installation steps below
- When you launch Citrix, make sure you ALLOW pop-ups, if asked!
Here are the steps to install Citrix for the first time:
For Ubuntu you will need to download the *.deb version and install through the software center
Now you need to get the certs to work properly in Firefox:
Refer: https://www.geekpete.com/blog/ssl-error-61-using-citrix-ica-client-on-linux/
You are going to copy the certs and create a symbolic link for all of the certs then:
$ sudo mv /opt/Citrix/ICAClient/keystore/cacerts /opt/Citrix/ICAClient/keystore/cacerts_old
$ sudo cp /opt/Citrix/ICAClient/keystore/cacerts_old/* /usr/share/ca-certificates/mozilla/
$ sudo ln -s /usr/share/ca-certificates/mozilla /opt/Citrix/ICAClient/keystore/cacerts
