Have you restored the full stock firmware? If not then do that first using: https://pixelrepair.withgoogle.com/carrier_selection

I don't recommend using the Pixel Repair Tool unless absolutely necessary.
If you are trying to return your device to absolute stock, I recommend using the Android Flash Tool. You can choose which factory build to flash, whether to wipe the device, and whether to relock the bootloader.

It is likely that you rooted your phone at one point, or perhaps flashed an alternative operating system which does not support verified boot.
Traditionally but not in all cases, re-locking your bootloader requires you to be unequivocally 100% stock. If you plan on being on stock and you are not (which I am assuming), you can either follow the # Flashing Instructions steps on the Nexus/Pixel Factory Images page. If you find that a bit tedious, there is always the flash-all.sh/flash-all.bat which will do this all for you.
After this, your device will be set straight back to factory, and you can follow the steps to re-lock your bootloader.

This is why I like to recommend the Android Flash Tool - simply from a perspective of ease of use, and the fact it's practically impossible to get wrong; additionally, the user can elect to lock the bootloader during the process when choosing the flash options. This removes the need to do anything else manually; the tool takes care of the entire process.
It's also very useful for updates.
