Hello Lynckia,

I have tried to install Licode on Ubuntu 16.04 (​Linux user-VirtualBox 4.4.0-31-generic #50-Ubuntu SMP Wed Jul 13 00:07:12 UTC 2016 x86\_64 x86\_64 x86\_64 GNU/Linux) doing the instructions you have written on the webpage

[http://lynckia.com/licode/install.html](http://lynckia.com/licode/install.html)

and when I had to install Erizo I get an error that said:

We don’t officially support Ubuntu 16 atm. There’s people making it work in this thread -  
[Any plan to support newer versions of Ubuntu?](http://discourse.lynckia.com/t/any-plan-to-support-newer-versions-of-ubuntu/456/6)

However, any change that we make in the installation process may break that since we only actively test in Ubuntu 14.04 and Docker for now.
