As of the publication of this article, the CA Client Automation (ITCM) agent on Linux is a 32-bit application.  In order to successfully install the application on Linux, there are 3rd party 32-bit libraries that must be installed as prerequisites.

What external libraries are required as prerequisites to installing the Client Automation (ITCM) agent on Linux?

CA Client Automation (ITCM) -- ITCM r14 SP2 and earlier.

Hint: ITCM r14 SP3 and forward is planned to be a 64-bit agent, therefore may require different prerequisites.
