The best way to identify which package and its version to install if we just know the name of package is to use “apt-cache” command on Ubuntu.
We just knew we wanted to install libpangox , so using below command I identified the exact version and package name.
$ sudo apt-cache search libpangox libpangoxft-1.0-0 - Layout and rendering of internationalized text libpangox-1.0-0 - pango library X backend libpangox-1.0-dev - pango library X backend - development files
as we can see, we got the package name and version as “libpangox-1.0-0”
so we can install this as,
$ sudo apt-get install libpangox-1.0-0
