Compute Station Linux Kernel

Supported Linux Kernels

Three of the four Compute Station types use Linux Kernels under their main operating systems.


Note the Operating Systems shown in the diagram are just the main one used for a particular station type, other are Operating Systems are also possible. For example, using Ubuntu in Mesh Stations and Debian in Home Stations.

As of 2022-12-01 all Linux kernels in Compute Stations are Linux Long Term Release (LTS) kernels.

Official LTS Kernel Ubuntu Openwrt Armbian Debian Support
5.4 Y Y Y Maintenance
5.10 Y Y Y Production
5.15 Y Y Y Testing

The above kernel versions supported globally, your local modular assist might support extra versions.
