Hi,
I've built my own Ubuntu Armbian image for the NanoPi Duo so I could use Ubuntu Snaps without classic confinement (The pre-built images don't seem to have SquashFS Compiled in the kernel).
The image seems to be working perfect. However I've noticed one thing which I'm not sure if it's the image or a generic armbian issue but I've noticed that every time I reboot it the mac address updates. I'm using it for a server so having it generate a new IP each time I need to reboot it for development is a bit of an issue.
Is there a recommended way to set a static one or such?
