The Citrix client allows you to use Windows tools on Linux and OSX. Visit the link at https://citrix.fb.wur.nl/ and login with your WUR account. Next install the free ICA client from [[Citrix]]. When you click on an icon in the browser, the application should fire up.
Select the Debian package (.deb extension) from the Citrix site. Download it and, for example
sudo dpkg -i icaclient_12.0.0_i386.deb
Now the certificates may not be found, resulting in a 'Addtrust External CA Root' not allowed (61) error. Copy the Mozilla certificates in place with
dpkg -L icaclient # check locations sudo cp -vau /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts
Now it should just work (tm).
