Hello first time,
I have been trying to install OpenFoam on my ubuntu 11.04. I just paste the code from the official website:

VERS=`lsb_release -cs`
sudo sh -c "echo deb http://www.openfoam.org/download/ubuntu $VERS main > /etc/apt/sources.list.d/openfoam.list"

then I write a password and enter and nothing happens.
It is my first linux and first instalation, please help me and be tolerant.
Thank you.
