Hi, when trying to run undervolt I get:

$ sudo undervolt -r
temperature target: -2 (98C)
Traceback (most recent call last):
  File "/usr/local/bin/undervolt", line 8, in <module>
    sys.exit(main())

SOLVED: Secure boot not disabled, had to put a "supervisor password" on BIOS, disable secureboot and then remove the password...

ADD ACER ASPIRE A315-53G-551Y on supported devices!!
