I am following this link to install pymol. I need libfreetype6-dev as a dependency, but it cannot be installed.

OPTION ONE
If you don't need version 1.8 and if you are using Ubuntu 14.04 or newer, you can install version 1.7 through the official Ubuntu repositories. Just run the following commands to install pymol version and pymol dependencies:
sudo apt-get update sudo apt-get install pymol If it still complains about libfreetype6-dev, run the following commands to fix that and then run the above commands again.
sudo apt-get clean sudo apt-get update sudo apt-get purge libfreetype6-dev To search for available packages through apt-get, run the following command like in this example:
apt-cache search pymol To narrow the results to those containing a particular word, use grep like in this example:
apt-cache search pymol | grep pymol To list the available version:
apt-cache show pymol | grep "Version:" To list more info:
apt-cache show pymol OPTION TWO
Alternatively, if you insist on installing the downloaded version, run the following commands to install libfreetype6-dev:
sudo apt-get clean sudo apt-get update sudo mv /usr/share/man/man1/freetype-config.1.gz ~/ sudo apt-get install libfreetype6-dev This will move the manpage file to your home directory so you will have to view the file from there instead of using manpage.
