System requirements
Linux distributions
Note:
System requirements for components not covered here (such as Citrix Workspace app) are described in their respective documentation sets.
Starting with the CU3 release, install .NET Core Runtime 3.1 as a prerequisite before you install the Linux VDA. For more information, see https://docs.microsoft.com/en-us/dotnet/core/install/linux-package-managers.
The Linux VDA does not support SecureICA for encryption. Enabling SecureICA on the Linux VDA causes session launch failure.
For information about using a Current Release (CR) in a Long Term Service (LTSR) environment and other FAQs, see Knowledge Center article.
The Linux VDA supports the following Linux distributions:
Important:
When the support from your OS vendor expires, Citrix might be limited in its ability to remediate problems.
For deprecated or removed platforms, see Deprecation.
