+Linux servers can be configured as [deployment targets](/docs/infrastructure/deployment-targets) in Octopus.
 
 The Octopus Server can communicate with Linux targets in two ways:

 - Using the [Linux Tentacle](/docs/infrastructure/deployment-targets/tentacle/linux).

 When using SSH for deployments to a Linux server, the Tentacle agent is not required and doesn't need to be installed.

 If you operate in a highly secure environment, where it's not possible to open an inbound TCP port for Tentacle (`10933` by default), you can configure the Linux Tentacle in [Polling mode](/docs/infrastructure/deployment-targets/tentacle/tentacle-communication/#polling-tentacles).

 - The `$HOME` environment variable must be available.

 - `tar` is available. This is used to unpack Calamari.
 - `base64` is available. This is used for encoding and decoding variables.
 - `grep` is available.
 
-Any Linux server which meets these minimum requirements will be able to be configured as a deployment target or worker. However, there are additional requirements to be aware of for both [SSH targets](/docs/infrastructure/deployment-targets/linux/ssh-requirements) and [Linux Tentacle](/docs/infrastructure/deployment-targets/tentacle/linux/#requirements).

 ## Supported distributions
 
-The following platforms are explicitly supported (we run automated tests against them):
+Since tooling used to invoke Octopus workloads is based on .NET 6, Octopus Server supports running workloads on the following distributions as per the [.NET 6 supported platform details](https://github.com/dotnet/core/blob/main/release-notes/6.0/supported-os.md#linux).

+
+Although the tooling requires the platform to support .NET Core, since it runs as a self-contained .NET deployment there is no .NET _installation_ prerequisite.
 
-- Ubuntu 22.04 LTS
-- Redhat (RHEL) 8.10
-- Amazon Linux 2
-- Debian 11
-- MacOS 12.6.3
-- openSUSE 15.6
-- SUSE LES 15 SP5
+In addition to the .NET 6 requirement, Octopus will only support those Operating Systems which are themselves still considered as supported by the platform vendors themselves.
