Grub is giving me "error: device name required"

As the title says, I get that error when booting any of my boot options; I have Arch with linux-ck, Arch with linux, and Windows 10. They all do eventually boot and work fine, but it takes a few seconds, and I'm worried that this inconvenience might grow into something more sinister. My Google-fu only led me to this relevant link. Is the cryptomount -u option supposed to have a UUID following it? Because all of my grub.cfg entries have cryptomount -u, but no UUID following.

Thanks in advance.

Re: Grub is giving me "error: device name required"

Post your grub.cfg and the output of `lsblk -f`

Are you infected with Wetiko?

Re: Grub is giving me "error: device name required"

I had the very same error. It is caused by "GRUB_ENABLE_CRYPTODISK=y" in your /etc/default/grub
If your boot partition is not encrypted - just comment this entry out and regenerate your grub config.
