How to install Wkhtmltopdf

Solve 'Unable to find Wkhtmltopdf on this system'

Ok - let's make things short. Odoo is using Wkhtmltopdf dependency to print pdf files. If you installed Odoo and haven't installed Wkhtmltopdf then you won't be able to print pdf and your customers won't be able to finalise their transaction in some cases (they will get "Internal Server Error"). This tutorial will show you how to install and configure Wkhtmltopdf with Odoo 12 and Ubuntu Linux 18.04

What is Wkhtmltopdf?

It is an open source tool to render HTML to pdf. 

The installation may be as simple as:

pip install wkhtmltopdf

However, with Odoo it is a bit more complicated.

Wkhtmltopdf & Odoo

Depending on the version of Odoo you are using as well as operating system the different version may be required. That is why there are so many posts like "I have Wkhtmltopdf bu documents won't print". Odoo 8 is compatible with different version than Odoo 12. If you just installed the latest version of Wkhtmltopdf, then you may have to repeat the process and install the correct one.

Information on supported Wkhtmltopdf and Odoo versions you can find on

Let's install Wkhtmltopdf

As mentioned before this tutorial will base on the Odoo 12 installed on Ubuntu Linux 18.04

Before you start - make a backup. It is easier to restore the instance than fix it. If you are already a superuser, you don't need to type sudo in fornt. First download the package:
sudo wget

Unpack it:

sudo dpkg -i wkhtmltox_0.12.1.3-1~bionic_amd64.deb
sudo apt-get install -f
sudo ln -s /usr/local/bin/wkhtmltopdf /usr/bin
sudo ln -s /usr/local/bin/wkhtmltoimage /usr/bin

The reason for this tutorial is to put more light on the case. I have already written one on this topic and it can be found
