Help needed for OpenThread BorderRouter

[MeGreen]

Hello everybody,

i am trying to setup an OpenThread BorderRouter to control my Nanoleaf Essential Bulbs. (their app is just... not so good :) )

I ordered the USB Dongle Version. I don't have a Raspi, but i have a Laptop from 2013 that i don't actively used, so i thought i would just use this. I installed Ubuntu 21.10 on it.

I am stuck at "Verify Services". I would say i completed the steps before, and installed wpantund and BorderRouter.
Unfortunately wpantund.service didn't show up when using "sudo systemctl status". I've been able to get it start with a minimal working example from this stackoverflow
https://unix.stackexchange.com/questions/478999/how-can-i-make-an-executable-run-as-a-service

but when i use "sudo wpanctl status" i don't get the expected output, but instead a message that the given network interface doesn't exist or isn't managed by wpantund.

I guess what would help, if someone could share their wpantund.service file. But also it would be nice to know why it wasn't created in the first place.

One mistake i guess i could have made was that i installed wpantund after BorderRouter, but i have repeated the bootstrap and setup script after that.
