Please note that libsdl2-dev has an unversioned dependency on libpulse- dev.
There seems to be a local version mismatch between the libpulse packages: “libpulse-dev : Depends: libpulse0 (= 1:11.1-1ubuntu7.4) but 1:11.1-1ubuntu7.5 is installed”. Did you have the bionic-proposed repository enabled at some point but don't have it anymore? I think if you enabled the proposed updates then you might be able to install libpulse-dev again. ** Package changed: libsdl2 (Ubuntu) => pulseaudio (Ubuntu) ** Changed in: pulseaudio (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863186 Title: package sdl2-dev depends on outdated version of libpulse-dev To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1863186/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
