Horizon Agent for Linux has some dependency packages unique to a Linux distribution. You must install these packages before installing Horizon Agent for Linux.


Verify that a new virtual machine (VM) is created in vCenter Server and your Linux distribution is installed on the machine.


  • Install the mandatory packages that are not installed or upgraded by default. If any package does not meet the requirement, the installer breaks the installation.
