LUKS shouldn't matter David, I've never used it in 20 years. However I
just installed locate, updatedb, the locate luks spit out this:
oot@picnc:~# locate luks
/boot/efi/boot/grub/arm64-efi/luks.mod
/boot/grub/arm64-efi/luks.mod
/usr/lib/grub/arm64-efi/luks.mod
Could one of those be screwing with me?
Cheers David, Gene Heskett
