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
# dpkg --get-selections | grep hold
