 Linux Tentacle is a .NET application distributed as a [self-contained deployment](https://docs.microsoft.com/en-us/dotnet/core/deploying/#publish-self-contained). On most Linux distributions it will *just work*, but be aware that [you will need to install some prerequisites](https://learn.microsoft.com/en-us/dotnet/core/install/linux-scripted-manual#dependencies).
 
+Linux Tentacle is built on .NET 10, so the server's C library must be at least the version [.NET 10 requires](https://github.com/dotnet/core/blob/main/release-notes/10.0/supported-os.md#libc-compatibility):

+| x64          | glibc 2.27, or musl 1.2.3 for the `linux-musl-x64` archive |

+ARM32 servers need a distribution at least as new as Debian 12, Ubuntu 22.04 or Raspberry Pi OS (bookworm).

 ### Git-based steps \{#git-based-steps}
 
 Git-based steps (steps that clone or fetch from a git repository as part of a deployment or runbook) require OpenSSL **1.1** or **3** on the host. Tentacles running with other OpenSSL versions will fail when running these steps.
