Error while loading shared libraries: libXrender.so.1 on Linux

I am trying to use wkhtmltopdf command to create and convert html pages to a pdf. However, I am running into errors though as follows when try to use wkhtmltopdf via a shell or Python script:
     Creating foo.pdf …
     ~/bin/wkhtmltox/bin/wkhtmltopdf: error while loading shared libraries: libXrender.so.1: cannot open shared object file: No such file or directory
     Error: foo.pdf not found.
How do I fix this problem with out installing the xserver on my Ubuntu or Debian server?

You can find the missing libs using the ldd command:
$ ldd /path/to/wkhtmltopdf
Sample outputs:

Now you can search for missing libs using:
$ apt-cache search libXrender
In my case the following were missing

1. libXrender: X Rendering Extension client library
2. libfontconfig1: generic font configuration library – runtime

Fixing error while loading shared libraries on a Ubuntu/Debian Linux

Armed with this new info, I need to use the following apt-get command or apt command to install libxrender1 and libfontconfig1 to solve this issue:
$ sudo apt-get install libfontconfig1 libxrender1
OR
$ sudo apt install libfontconfig1 libxrender1
If you are using any other Linux distro you need to search as described above and install missing libs.
