Hi Ashish,
Thanks for your valuable feedback.
I have already gone through #3001 but unable to find steps for the solution in Ubuntu 18.04.
I really appreciate your help.
Thanks

@alagiyanirav sudo apt install libssl1.0-dev on Ubuntu 18.04 worked for me.

@pla1 This works for me too on Debian Stretch

I have same problem after installing sudo apt install libssl1.0-dev.
Is there any other option. I am using h4cc/wkhtmltopdf-amd64 to print PDF in ubuntu lamp localhost.

Please use the latest version of wkhtmltopdf. If you're using some wrapper, please ask them to update their package, can't help you there.
