Skype doesn't work on Linux Mint 16 x86_64

Alright, it's time for Linux Mint to become less polished.

UPDATE: The solution applies for Ubuntu 14.10, too (respectively, the problem arises in Ubuntu 14.10 as well).

If you install Skype on Linux Mint 16 x86_64 (KDE) you, you may find out the app won't start. And if you run Skype from the terminal to see what the error is and what the matter is, you may see the following:

skype: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory

If you this error, here's how to fix it:

sudo ln -s /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1 /usr/lib/libGL.so.1

This creates a link to the not found file / library.

Then on running Skype from the terminal, you may see another error: 

skype: error while loading shared libraries: libGL.so.1: wrong ELF class: ELFCLASS64

Go on:

sudo nano /etc/ld.so.conf.d/skype.conf

and add the following line in it

/usr/lib/i386-linux-gnu/mesa/

save & exit
and lastly run

sudo ldconfig -v

Now Skype should start up and run normally.
