           Summary: winehq-staging and winehq-devel packages are broken

I followed the instructions for installing on Linux Mint 19.x/Ubuntu 18.04
(https://wiki.winehq.org/Ubuntu). I was able to install winehq-stable just
fine, but I get the following message from apt when trying to install
wine-staging or wine-devel:

The following packages have unmet dependencies.
 winehq-[staging/devel] : Depends: wine-[staging/devel] (= 4.9~bionic)

The conflicting packages are wine, wine-amd64 and wine-i386. To make sure these
conflicts weren't because of winehq-stable, I removed it and all other
WINE-related packages from my system and tried again, but got the same error
messages.
