Do you have Magisk installed? Do you have TWRP installed? Either one would prevent it. (If you have Magisk installed, you can uninstall it from the app, then reinstall it after the update.)

I don't have Magisk or TWRP installed, but still have the problem

Welcome to Android Central! I merged your duplicate threads.

I had a similar problem on my Pixel C earlier in the month. After a couple of days, it eventually installed correctly. When I was searching about this problem, I did see some mentions that it was also happening on some Pixel phones. Give it a few days, and then try updating again.

Thx B. Diddy, will try again in a few days, it seems whenever i connect to wifi it tries to update and keeps sending the error message.

Or, if you were so inclined, you could flash the OTA image. It's available on the Google website.

That still seems to be dangerous. I had one phone (a 2, not a 2 XL, but it's pretty much the same files) replaced for doing that, and the replacement locked up in the fastboot screen flashing a later update and Google was going to replace it, until I figured out how to force a total factory reflash. I'd wait. (That's what I plan on doing in May.)

There's a big difference between flashing and sideloading. Sideloading an OTA is no more risky than receiving the same OTA through its normal distribution channel.
