Tailscale on ubuntu ?

2025-05-18 6:54

Dear admin,

I want to use a Tailscale subnet router on Ubuntu with my Luckfox Lyra Ultra device, but I'm encountering quite a few errors.
For example, the kernel doesn't support TUN, iptables, or IPv6. I tried building the kernel with those options enabled, but when I flashed it to the device, it couldn't boot. Please help me!!

Hello, currently we no longer provide support for the Ubuntu image of Luckfox Lyra. The attachment is a kernel configuration for running tailscale under buildroot, which can be used as a reference. Further adjustments are required based on your specific usage. Since some compiled files in .ko format are directly included in the kernel, it is necessary to re-execute the entire ./build.sh process. We hope this helps you. Running tailscale under buildroot also requires installing iptables and ip6tables (configure using ./build.sh buildroot-config).

Thank you for your suggestion. I successfully ran Tailscale with the subnet router feature. However, to run it fully, some kernel customizations are needed, such as xt_mark, etc.
