Citrix Workspace app 1809 for Linux

Connecting this version of Citrix Workspace app for Linux to Citrix Workspace services is an experimental feature.

Introducing Workspace launcher

Previously, the browser plug-in provided along with Citrix Workspace app for Linux enabled users to launch published desktops and applications. This plug-in was based on the Netscape Plugin Application Programming Interface (NPAPI).

Mozilla Corporation has announced that NPAPI support is deprecated as of version 52 of the Firefox browser. Other browsers, too, have deprecated support for NPAPI.

As a solution, Citrix is introducing Workspace launcher (WebHelper). To enable this feature, configure StoreFront to send requests to Workspace launcher in order to detect the Citrix Workspace app installation.

For information about configuring StoreFront, see Solution – 2 > a) Administrator configuration in Knowledge Center article [CTX237727](https://support.citrix.com/article/CTX237727).

Note: Citrix Workspace launcher currently works only with direct connections to StoreFront. It is not supported in other cases such as connections through Citrix Gateway.

Disabling new workspace web UI mode

When you launch the Citrix Workspace app for Linux using self-service executable file from third-party thin client vendors, the application can become unresponsive due to 100% CPU utilization. 

As a workaround, to switch back to the old UI mode:

 1.  Remove cached files by using the command:

       rm -r ~/.ICAClient

 2.  Go to $ICAROOT/config/AuthManconfig.xml file.

  3.  Change CWACapableEnabled key value to false.

  4.  Launch Citrix Workspace app for Linux. 

       Observe that the self-service executable file loads the old UI.

The difference between packages that offer support for Citrix Web Workspace app and those that support self-service is that the latter packages include dependencies required for self-service in addition to those needed for the Citrix Web Workspace app. Dependencies for self-service are a superset of those required for Citrix Web Workspace app, but the files installed are identical. 

If you only require Ciitrix Web Workspace app support, or your distribution doesn’t have the necessary packages to support self-service then install the Citrix Web Workspace app only package.

If your distribution allows, install Citrix Workspace app from the Debian package or RPM package. These files are generally easier to use because they automatically install any required packages. If you want to control the installation location, install Citrix Workspace app from the tarball package.
