This is strange. You may have already solved your problem, but have you checked your apt sources list that it points to the right source (stable / oldstable) or (bookworm/trixie)?

Related to this, there is a note in the release notes for upgrading to Debian 13: https://www.debian.org/releases/trixie/release-notes/issues.html#ensure-boot-has-enough-free-space

It mentions an increase in the minimum requirements for /boot partition.

Correct, but it is worth to point out that once you continue your subscription, you can continue playing those games.
