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 Core Runtime 3.1 according to the instructions at https://docs.microsoft.com/en-us/dotnet/core/install/linux-package-managers.
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.

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.
The Linux VDA supports several methods for integrating Linux machines with Microsoft Active Directory (AD):
