Wkhtmltopdf error since last update


#1

Since last update I get this error message when outputting things as PDF.

The version of wkhtmltopdf is correct: wkhtmltopdf 0.12.3 (with patched qt)

Traceback (most recent call last):

Not quite correct - wkhtmltopdf 0.12.5 is better.

#apt install wkhtmltopdf -y #[installs an “old” version which is not good]
apt install xfonts-75dpi -y
wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.stretch_amd64.deb
dpkg --install wkhtmltox_0.12.5-1.stretch_amd64.deb

Thank you! Installing the 0.12.5 version solved the problem.

I just had to change the download link for WGET to the packet for my Ubuntu installation.

If anyone needs to know, here you find the download links to all the different packets: https://github.com/wkhtmltopdf/wkhtmltopdf/releases/
