Failed to open MSR device: Permission denied and Failed to setup the program

[Yuki338n]

Hello, every time i prompt any command like intel-undervolt apply or even intel-undervolt read this shows up: Failed to open MSR device: Permission denied Failed to setup the program why?

[precla]

tried with sudo intel-undervolt ...?

Have you disabled secure boot?

As precla stated earlier, this just means you need to run it as root through sudo intel-undervolt apply

This is a bit annoying, so another way to do this is to add yourself to the sudoers file for intel-undervolt by running sudo EDITOR=nano visudo and then adding a line like such: your_username ALL=(ALL) NOPASSWD: /usr/bin/intel-undervolt. This way, you can just run intel-undervolt ... without any permissions issues
