When running undervolt --read

modprobe: ERROR: could not insert 'msr': Operation not permitted
Traceback (most recent call last):
  File "/home/qaz/.local/bin/undervolt", line 11, in <module>
    sys.exit(main())
  File "/home/qaz/.local/lib/python2.7/site-packages/undervolt.py", line 386, in main

    raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['modprobe', 'msr']' returned non-zero exit status 1

Using Intel i7-8750H (12)

I also tried sudo undervolt --read, which gave me the following error message: sudo: undervolt: command not found
