mosquitto-clients : Depends: libmosquitto1 (= 1.5.7-1) but 1.5.7-1+deb10u1 is to be installed

It looks like libmosquitto1's version was incremented but mosquitto-clients Depends was not bumped to match. This makes it impossible to install mosquitto_pub and mosquitto_sub for IoT use.

I've discovered a workaround until the dependencies can be corrected:

apt download mosquitto-clients
sudo dpkg --force-all -i mosquitto-clients_1.5.7-1_armhf.deb

I have a better workaround in the form of a shim package that Provides: libmosquitto1. This leaves apt in a working state. Simply install the attached shim package (or use the .equivs file to build your own) and after that you can sudo apt instal mosquitto-clients.

Is this still an issue? Everything looks okay on this end.
