Looks like you are using wkhtmltopdf version with unpatched Qt.
What does wkhtmltopdf --version show?

Also please use “preformatted text” format for the logs.

Keep in mind that the last 4 commands given in the instructions in the link are for Ubuntu 32bit exclusively. If you are using Ubuntu 64bit they will be different. He kind of says that in the instructions, but it’s easy not to read the instructions when you have commands right in front of you.

Le_Ba_Chau · August 2, 2016, 10:48am

here is my currently version wkhtmltopdf 0.12.2.4

Marcin_Walkow · August 2, 2016, 10:57am

This is like blaming somebody for wrong cake when you focused on ingredients only
But yeah - this is for 64 bits - I rarely see 32 bits on servers btw.

Dbone · August 2, 2016, 11:22am

Haha so true. Not blaming the author though, I just know that being a noob myself with Linux there’s so many things to learn that sometimes I just glaze over when someone gives me a quick fix to a problem.

Looking back at the post it would be pretty foolish to follow those last 4 commands (from 2013) and try to install version 0.9.9 - some mornings though, when nothings working, I would’ve tried without thinking.

I had this exact wkhtmltopdf problem a couple of weeks ago: [V7] Wkhtmltopdf error
When no one replied I did a full wipe and reinstall to solve it.

You’re probably right about not many 32 bit servers around, but Digital Ocean still offers them, and the ERPNext VM I believe is also 32 bit.

Le_Ba_Chau · August 2, 2016, 12:16pm

Sorry i am newbie in ubuntu
so anybody help me plz my ubuntu 16.04 x64
i don’t know how to solve this problems.

Remove existing installation:

sudo apt-get remove --purge wkhtmltopdf

Download wkhtmltopdf patched with qt using below command

sudo wget -P Downloads http://download.gna.org/wkhtmltopdf/0.12/0.12.1/wkhtmltox-0.12.1_linux-trusty-amd64.deb

Here, replace “trusty” with your OS name and if 64 bit only then keep “amd64” like that , otherwise change it to “i386” and down load the deb file.

After that execute the following commands,

cd ~/Downloads
sudo dpkg -i wkhtmltox-0.12.1_linux-trusty-amd64.deb

Now, check wkhtmltopdf version with below command,

wkhtmltopdf -V

Wow it work now thank you @Dadaso_Zanzane

Joshua_Pinter · November 14, 2017, 10:40pm

Steps for install 0.12.3 on Ubuntu 16.04.

Because I wasted way too much time tracking this down, here is for others stumbling on this:

cd ~
wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.3/wkhtmltox-0.12.3_linux-generic-amd64.tar.xz
tar vxf wkhtmltox-0.12.3_linux-generic-amd64.tar.xz 
cp wkhtmltox/bin/wk* /usr/local/bin/

And you can confirm with:

$ wkhtmltopdf --version
wkhtmltopdf 0.12.3 (with patched qt)

Btw, I chose 0.12.3 instead of 0.12.4 because of a strange page sizing issue, discussed here:
