Mint update from 18.3 to 19 – Wine broke

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 bionic main'
wget -nc
apt-key add Release.key

Check if you do not have duplicate lines from an earlier install.

vi /etc/apt/sources.list.d/additional-repositories.list

Then the final step.

apt-get update

apt-get install --install-recommends winehq-stable

Unknown media type in type Fix

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:

cd /usr/share/mime
grep -R all/all *

in kde xml, remove the sections containing:
<mime-type type="all/allfiles">
<mime-type type="all/all">

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
