Changes to a file are undone after a restart.

 Armbian 22.05.0-trunk  with bleeding edge Linux 5.16.20-rockchip64

 

my armbian runs on a MKS SKIPR motherboard for a 3d printer.

Since I updated the system, I can no longer change any files. I change it but after a restart the file is back as it was.since i have updated the system

for example this file
nano /etc/resolv.conf
After saving and restarting everything is as it was. no matter whether as root or user

 

Is there a setting that prevents or reverses changes?

Contact people that sold you this device and software pack. It has nothing to do with Armbian. It was just assembled with our tools ...
