Moto G7 Bootloader Unlock Error


I just joined and am relatively new to messing with android phones in terms of de-googling them. I have some experience with trying out different distros on the PinePhone I bought a few months ago, but ultimately decided that none of the available distros are ready for use as a daily driver. I am currently trying to unlock the boot loader on two Moto G7’s (one for me and one for my mother)to install Lineage OS, but keep on getting an error message in SDK tools. I have already enabled USB debugging and OEM unlocking, but when typing in adb, i get the following error message:

(bootloader) Unlock data:
(bootloader) Unlock data unavailable
(bootloader) Failed
OKAY [ 0.016s]
Finished. Total time: 0.016s

Please help!
