if you are using ODOO version 8 and getting some error like –

Unable to find Wkhtmltopdf on this system. The report will be shown in html.

It means you need to upgrade the version of Wkhtmltopdf library on your server.

Let me elaborate this problem first-

As we all know, when we install ODOO-version 8 on the server, we have also install some necessary libraries too like – python-decorator, python-werkzeug and many more libraries. ” Wkhtmltopdf ” is also one of them. Now, lets come to the main problem, when we install “wkhtmltopdf” on server, using command like –

sudo apt-get install -y wkhtmltopdf

this command install an outdated wkhtmltopdf and odoo generate a wrong pdf (with 0 byte ) and popup error saying to update to the new wkhtmltopdf. So this is not a ODOO Error, but we can say it`s a wkhtmltopdf issue(moreover it`s a version issue).

Solution is to upgrade ” wkhtmltopdf ” to 0.12.1 like this –

1) Download wkhtmltopdf version from  depending on your system arch (32 or 64 bit) –

# For 64-bit - Linux (Ubuntu Trusty) - Ubuntu 14.04 sudo wget http://sourceforge.net/projects/wkhtmltopdf/files/archive/0.12.1/wkhtmltox-0.12.1_linux-trusty-amd64.deb # For 64-bit - Centos- 7.1.1503 (Core)  sudo wget http://sourceforge.net/projects/wkhtmltopdf/files/archive/0.12.1/wkhtmltox-0.12.1_linux-centos7-amd64.rpm

2) Install the downloaded package as –

# For Ubuntu sudo dpkg -i wkhtmltox-0.12.1_linux-trusty-amd64.deb # For Centos sudo rpm -Uvh wkhtmltox-0.12.1_linux-centos7-amd64.rpm

3) Copy files as –

sudo cp /usr/local/bin/wkhtmltopdf /usr/binsudo cp /usr/local/bin/wkhtmltoimage /usr/bin

4) Restart Odoo server and then try again.

That`s it !!! I hope it will help someone.
