Wkhtmltopdf: help with Ubuntu 16.04

[mikereape]

Hi

I'd be very grateful for any help with this. I'm trying to get this running on WSL Ubuntu 16.04 x86_64.
This is all completely new to me. I understand about the XDG_RUNTIME_DIR problem (tho don't know how to fix it) but the rest I haven't a clue about. Why is it failing to get screen resources when there's no screen involved? Do I need the relevant version of Qt running or something.

Thanks for any help. Apologies if there's other info I should have provided and haven't

Here's the output:

try add this to you bashrc
export QT_QPA_PLATFORM='offscreen'

@jesoonluo, thanks, it worked for me (Ubuntu 18.04)

Looks like you're using the distro-provided package instead of the one from the downloads page -- it's going to require xvfb running.
