fan-control is distributed with flatpak on Linux, which allows containerization. But fan-control need to access your sensors to work. This is why we use udev, which allows normal user to access devices, without giving them sudo permission. This is the rule that you need for fan-control.
wget https://raw.githubusercontent.com/wiiznokes/fan-control/master/res/linux/60-fan-control.rules
sudo mv 60-fan-control.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules && sudo udevadm trigger- wget: download the rule in your current directory
- sudo mv: move the rule where it need to be
- udevadm: reload the rules
You need to disable the read only mode temporarily
