Did you change all references in sources.list and sources.list.d/raspi.list? Did you run apt update before the upgrade?
i thought it is because i installed something on the used old system that breaks this.
so i made a fresh installation...
i flashed a new sd-card with image 2021-05-07-raspios-buster-armhf.zip made an apt update & apt full-upgrade, rebooted the system, then i renamed buster to bullseye of the two source files and made an apt update ... (the update tells that there are more than 1000 updates available)
even then i get the same error message at apt full-upgrade.
