After updating from Linux Mint 18.3 to 19, wine stopped working. This is what was required to correct.
sudo all below commands if required
dpkg --add-architecture i386
apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main'
wget -nc https://dl.winehq.org/wine-builds/Release.key
apt-key add Release.key
Check if you do not have duplicate lines from an earlier install.
Then the final step.
apt-get install --install-recommends winehq-stable

Hope this does not bring a lot of issues with spam.
If Linux Mint 19 (Tara) shows error during update fril 18.3.
Unknown media type in type 'all/all'
Unknown media type in type 'all/allfiles'
To fix run following with sudo user:
grep -R all/all *
in kde xml, remove the sections containing:
sudo vi packages/kde.xml
the other files showing these sections can remain untouched.
Then run following, no errors should occur
sudo update-mime-database /usr/share/mime
