Turn off SECURE BOOT in your BIOS and you will probably be fine... assuming that your Ralink driver is current.

In 16.04, it's now required that drivers be signed. Yours isn't. Did you compile the driver yourself? Are you using DKMS? Cheers, Al

  • Hi, thanks. But I can't find SECURE BOOT in my BIOS, my motherboard is asus psl-mx . I tried compile driver, but wifi still not working. I think, I don't use DKMS. – charlie12 Aug 27 '16 at 06:54

    Please review http://askubuntu.com/questions/762254/why-do-i-get-required-key-not-available-when-install-3rd-party-kernel-modules, where they talk about the ASUS settings. If that can't be found, then use the mokutil utility described there also. Cheers, Al – heynnema Aug 27 '16 at 14:14
