OSError: [Errno 8] Exec format error

Not sure if this is an issue or some fault from my side, it was working in my local system(installed long back) but not working in digital ocean server. Both are Ubuntu 14.

I followed instructions from this page - http://fedir.github.io/web/blog/2013/09/25/install-wkhtmltopdf-on-ubuntu/

Note that I was able to generate pdfs using terminal commands but not using pdfkit.

Please let me know if I missed anything.

Update - Solution from this link is working for me.

As @user1305989's comment, following is the solution,

Steps:

  1. At first install xvfb server:

    sudo apt-get install xvfb

  2. Get needed version of wkhtmltopdf from http://wkhtmltopdf.org/downloads.html.

    For Ubuntu 14.04 64-bit:

    wget http://download.gna.org/wkhtmltopdf/0.12/0.12.2.1/wkhtmltox-0.12.2.1_linux-trusty-amd64.deb

  3. Install wkhtmltopdf:

    sudo dpkg -i wkhtmltox-0.12.2.1_linux-trusty-amd64.deb

    Install dependency (if needed):

    sudo apt-get -f install

  4. Create symblic link in /usr/local/bin/:

    echo 'exec xvfb-run -a -s "-screen 0 640x480x16" wkhtmltopdf "$@"' | sudo tee /usr/local/bin/wkhtmltopdf.sh >/dev/null
sudo chmod a+x /usr/local/bin/wkhtmltopdf.sh
