FeatureNotFound: Couldn't find a tree builder with the features you requested: html5lib. Do you need to install a parser library?
Any idea how to solve this please?
Still hoping for some assistance here…
I solved this by updating the pdf library.
This is what I got from my bash_history file. Perhaps it may help you.
tar vxf wkhtmltox-0.12.3_linux-generic-amd64.tar.xz
cp wkhtmltox/bin/wk* /usr/local/bin/
Thanks a lot for your response. Checking the wkhtmltopdf version shows the following
wkhtmltopdf 0.12.3 (with patched qt)
Do I still need to update?
I would try it. If I recall. the issue was about some missing library that was preventing the PDF render. I cannot recall the details or the error message, but installing as described fixed the PDF issue for me. I had to restart the service, I also recall.
I uninstalled and reinstalled wkhtmltopdf but still getting the same error. What service exactly did you restart and how did you do it?

Fresh Ubuntu 16.04 server install followed by fresh ERPnext-Production Easy install on a local PC.
I log in without problem, everything seems to work until I try printing a PDF.
Can somebody help Please?

Here’s how I got around the issue:
Usually, the html5lib directory is available at the following locations
I however observed that the folder was missing from the 3rd location so I copied it over using the command below
cp /home/frappe/frappe-bench/env/lib/python2.7/site-packages/pip/_vendor/html5lib/. /home/frappe/frappe-bench/env/lib/python2.7/site-packages/html5lib
I followed this with a
Now the PDF feature is working. I created a Github issue and hopefully this will soon be addressed by the core team
