monodoc docbrowser is broken on modern distros #8659
Description
Steps to Reproduce
- Install monodoc package from stable Ubuntu 18.04 repo
- Run monodoc (docbrowser)
Current Behavior
Monodoc docbrowser crashes and outputs a stack trace to the terminal.
Expected Behavior
A functioning documentation browser.
This is because there is effectively no HTML engine packaged by modern distros for GTK2. I have a WIP PR to port Monodoc to GTK3 so it can use WebKit 2 in mono/mono-tools#50.
On which platforms did you notice this
[ ] macOS
[X] Linux
