Unable to upgrade from PVE 6.4 to 7

I've successfully upgraded my instance from 6.3 to 6.4, but now after switching the sources from buster to bullseye and try apt update && apt-dist-upgrade I'm seeing the following:

I've checked the upgrade guide to v7 but I'm stuck on this step.

Thanks in advance for the help!
