How to Install Wkhtmltopdf 12.4 with patched Qt?

• Fixed in 0.12.5 tested on ubuntu 18.04.
• wkhtmltopdf/wkhtmltopdf#3001 (comment)

For earlier version whos suffering from versionlock syndrome. Please follow the instructions to rollback to older SSL interface. Do not alarm by the fallback ssl interface, they received security patches for vulnerability discovered.

Current version of apt-get wkhtmltopdf does not come with Qt patch. There are some issue going with both Qt patched and non-patched. Most common use case is compatible with the patched Qt.
