Could not execute command lessc

[AyaYousef]

Impacted versions: 10

Steps to reproduce:

1. Install a new Odoo on Ubuntu 16.04
2. Create a new database
3. Install any module.
4. You will now get the error "Could not execute command 'lessc'"

Current behavior:
Odoo backend and website layout is corrupted and I get dozens of errors in the console. In these errors I noticed that all files that ends with .less are altered to .less.css as it shown in the screenshot provided. At the very top of the page I get message with "Could not execute command /usr/bin/lessc"

Error log:

Expected behavior:
I shouldn't get that error as I've installed a clean odoo using this guide, which I tried before on an other server with no problems

To solve it I tried the following solution refered in this link, but it didn't solve the problem

sudo apt-get install nodejs nodejs-legacy node-less
sudo apt-get install npm
sudo npm install -g less
sudo npm install -g less-plugin-clean-css
sudo ln -s /usr/local/bin/lessc /usr/bin/lessc
sudo ln -s /usr/bin/nodejs /usr/bin/node

Just for anyone searching about Mac OS X. I found the solution here: https://gist.github.com/jfie5/7343868

Especially this line helped me:

sudo npm install -g less

(npm is already installed on my OS X).

If you don't have npm then you need to install it first.
