Additional steps to Manual installation of the dependencies of EOS

Hello to all EOS enthusiast, if you try to manually install the dependencies of @eosio with a clean install Ubuntu 16.10, while following the instructions of the Manual installation of the dependencies you will get these errors:

Thanks to @deaddy and his article: First Install & Run of EOS on a Blank Ubuntu 16 we just need to a a few steps before the sudo apt-get update such as:

sudo nano /etc/apt/sources.list

Taken from this address: http://releases.llvm.org/download.html add these lines:

deb http://apt.llvm.org/xenial/ llvm-toolchain-xenial-4.0 main
deb-src http://apt.llvm.org/xenial/ llvm-toolchain-xenial-4.0 main

Save and Exit

Then after the addition, success!

And that's my suggestion for improvement. Let's make EOS the best it can be.
