System requirements
Linux distributions
Note:
System requirements for components not covered here (such as Citrix Workspace app) are described in their respective documentation sets.
Before installing the Linux VDA, install .NET Runtime 6.0 according to the instructions at 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 more information about using this 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.

- Ubuntu Server 16.04
Note:
CentOS project shifts focus to CentOS Stream. CentOS Linux 8, as a rebuild of RHEL 8, ends at the end of 2021. CentOS Stream continues after that date, serving as the upstream (development) branch of Red Hat Enterprise Linux. For more information, see https://www.redhat.com/en/blog/centos-stream-building-innovative-future-enterprise-linux.
When you use Citrix Provisioning to stream Linux target devices, create a separate boot partition on the single shared-disk image so that the provisioned devices can boot as expected.
Avoid formatting any partition with
btrfs. GRUB2 has an intrinsic problem finding btrfs partitions. GRUB stands for GRand Unified Bootloader.
For a matrix of the Linux distributions and the Xorg versions that this version of the Linux VDA supports, see the following table. For more information, see XorgModuleABIVersions.

At least one desktop must be installed.
Citrix Virtual Desktops
The Linux VDA is compatible with all currently supported versions of Citrix Virtual Apps and Desktops. For information about the Citrix product lifecycle, and to find out when Citrix stops supporting specific versions of products, see the Citrix Product Lifecycle Matrix.
The configuration process for Linux VDAs differs slightly from Windows VDAs. However, any Delivery Controller farm is able to broker both Windows and Linux desktops.

GPUs
To learn which NVIDIA GPU cards your Linux distribution supports, go to the NVIDIA product support matrix and check the Hypervisor or Bare-Metal OS, Software Product Deployment, Hardware Supported, and Guest OS Support columns.
Ensure that you install the latest vGPU driver for your GPU card. Currently, the Linux VDA supports up to vGPU 13. For more information, see NVIDIA Virtual GPU Software Supported GPUs.
