Bug Description

My system has been left unable to install libpulse-dev because the staging has caused a dead-lock.

The maintainer of libpulse has instructed me to open a bug against apt.

See: https://answers.launchpad.net/ubuntu/+source/pulseaudio/+question/699828

libpulse-dev wants a matched libpulse0 which is impossible.

This is on Ubuntu 21.10 impish-updates

There never was a non-ubuntu apt source in the config.

The apt db is up to date.

The system is up to date.

Thanks for the bug report.

Please ignore Chris.

This is not a bug in apt. Launchpad currently does not preserve an old version when a new one is phasing, so non-installability can happen occasionally.

For more details, see bug 1929082. I'm going to mark this as a duplicate.
