Here's a relevant stack exchange question: https://unix.stackexchange.com/q/192642/215718

What I recommend is don't use the Debian package (which doesn't support running headless). Grab the latest generic linux binary here: https://github.com/wkhtmltopdf/wkhtmltopdf/releases/tag/0.12.4

You'll want either wkhtmltox-0.12.4_linux-generic-amd64.tar.xz or wkhtmltox-0/usr/bin/.12.4_linux-generic-i386.tar.xz. Then copy the binary from wkhtmltox/bin to /usr/bin/ and you're done. It's also a newer version of wkhtmltopdf to boot.

Or you can use xvfb to wrap it as described here https://github.com/JazzCore/python-pdfkit/wiki/Using-wkhtmltopdf-without-X-server#debianubuntu

The wrapper script didn't work for me. But the binary from the GitHub release page did.

Note about wkhtmltopdf (0.12.4) in Ubuntu 18.04:

Reduced Functionality:
  This version of wkhtmltopdf has been compiled against a version of QT without
  the wkhtmltopdf patches. Therefore some features are missing, if you need
  these features please use the static version.

  Currently the list of features only supported with patch QT includes:
 * Running without an X11 server.

Solution from @WilliamDenniss worked for me!

Wrapping with xvfb worked for me, thanks :)

The solution from @WilliamDenniss works perfectly. Thank you so much.

Closing since its "fixed". Good idea to update wiki page about running without X server with an alternative binary from https://github.com/wkhtmltopdf/wkhtmltopdf/releases/

Sorry that it took so long for me to get to it...
