I recently got a new computer and erased windows 10 before booting it up.
Now I need windows for work so have been using wine on ubuntu.
It has been great!
All I did was
Which is completely the wrong way to install the Ubuntu wine package.
Which is (for bionic): wine-stable
A meta-package that should pull in the sub-packages: wine32 wine64
; which cover both the 32-bit and 64-bit architectures that Wine requires.
This is why "your" Wine version didn't automatically pull down wine-mono
, because your Wine installation is busted...
Having said all of that...
The Ubuntu bionic
Wine package, version 3.0
, is by now very obsolete
So you'd want to follow the instructions on: WineHQ Download: Ubuntu
; to get the most recent Wine (or Wine Staging release): 4.1
(at the time of writing).
