libpulse-dev installation problem

There seems to be an issue with libpulse-dev in Ubuntu 21.10 because if I want to install libsdl2-dev on a fully up-to-date system, I get:

The following packages have unmet dependencies:

libpulse-dev : Depends: libpulse0 (= 1:15.0+dfsg1-1ubuntu2) but 1:15.0+dfsg1-1ubuntu2.1 is to be installed

How do I solve this?

This is on a fresh 64b ubuntu21.10 install.

UPDATE

# apt-cache policy libpulse-dev

UPDATE 2

It seems to get libpulse0 from impish, but libpulse-dev from impish-updates, but why?

root@gamer2:/# apt-cache policy libpulse0
