Seams to be something related to wkhtmltopdf… And I saw something on the v12.0.8 release related to it

fix(travis): Install wkhtmltopdf

I did the update, and nothing happened…

Any kind light here?

Do you have wkhtmltopdf installed?
Try executing:

wkhtmltopdf --version
5

Try this command:

sudo apt-get update
sudo apt install wkhtmltopdf
sudo wget https://builds.wkhtmltopdf.org/0.12.1.3/wkhtmltox_0.12.1.3-1~bionic_amd64.deb
sudo cp /var/backups/dpkg.status.0 /var/lib/dpkg/status
sudo apt-get update
sudo dpkg -i wkhtmltox_0.12.1.3-1~bionic_amd64.deb
sudo apt-get install -f
sudo ln -s /usr/local/bin/wkhtmltopdf /usr/bin
sudo ln -s /usr/local/bin/wkhtmltoimage /usr/bin

6

I normally install later version of wkhtmltopdf using these commands…

#wkhtmltopdf - the default apt-get version is outdated. Install pre-reqs, and then a manual/latest version
sudo apt install -y xfonts-75dpi fontconfig libxrender1 xfonts-base
wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.stretch_amd64.deb
sudo dpkg --install wkhtmltox_0.12.5-1.stretch_amd64.deb

Still searching… Thanks for all your help… I’ll try to resend the message… let’s see…

The problem here is your local can’t display the PDF being forwarded to it from the remote. To connect two X window environments try this

ssh -X frappe@yourremoteip
