--- Comment #6 from Sveinar Søpler cybermax@dexter.no --- The conflict is due to the buildserver putting a timestamp in the changelog file, and this causes the i386 and amd64 packages to be "different" - and since the timestamp in the gz file is different, there is a different md5sum.
In the meantime you can just delete the changelog file and then install the :i386 package. sudo rm /usr/share/doc/libfaudio0/changelog.Debian.gz sudo apt install libfaudio:i386
The contents of the changelog is the same, save for the timestamp that differs a few seconds, so you are not "breaking" anything.
I will look into what causes this.
The missing libfaudio0 package on the winehq servers i have no control over sadly.
