frappe.exceptions.ValidationError: PDF generation failed because of broken image links

which version of wkhtmltopdf do you have? (recommended is 0.12.6+ qt patched)

Hi @trentmu , I got issue when I check version

wkhtmltopdf --version
wkhtmltopdf: error while loading shared libraries: libjpeg.so.62: cannot open shared object file: No such file or directory

does indicate that there is a missing library…try this
sudo apt install -y libjpeg-tools

and then retry the wkhtmltopdf --version command

I installed the last version, but got a new “time out issue”

from this post…Wkhtmltopdf layout error - #4 by lasalesi maybe check for
