Comix : "Could not find unrar executable. Please install it if you wish to open RAR achives"

Comix is the software used to open *.cbr and *.cbz files on Linux.

In Windows Comic Reader was my favorite but now that I have completely moved on to Linux, installation of Comix was deemed necessary.

Comix by default can open *.cbz files.

To open *.cbr files using Comix, you need to install the unrar executable by the following procedure.

$sudo apt-get install unrar

Done. :)
