wkhtmltopdf 12.6 raspberry pi unpatched qt

Question

i have the problem that my raspberry has a version of wkhtmltopdf installed that is not qt patched. But my research says that this is supposed to be fixed in version 12.6 and exactly this version I have installed. I just installed wkhtmltopdf with apt-get install wkhtmltopdf.

What else can it be?

Here's my Linux Version:

Linux raspberrypie 5.15.32-v8+ #1538 SMP PREEMPT Thu Mar 31 19:40:39 BST 2022 aarch64 GNU/Linux

Here's my wkhtmltopdf Version:

wkhtmltopdf --version
wkhtmltopdf 0.12.6

Here's the output if i want to add a footer or header:

wkhtmltopdf http://google.com --footer-center 'test' Test.pdf
The switch --footer-center, is not support using unpatched qt, and will be ignored.Loading page (1/2)
