I would like to use my umbrel node as a tailscale subnet router to reach other devices in my network via tailscale. To do this, I need to execute the command
$ sudo tailscale up --advertise-routes=10.0.0.0/24,10.0.1.0/24. (https://tailscale.com/kb/1019/subnets/)
Unfortunately, the shell keeps outputting that the command was not found. How can I reach the tailscale command?
