Yes the tutorial will be the same.
From OpenFOAM v3.0 to recent version of OpenFOAM, the spoken tutorial videos can be followed.
The major change from previous version is the location of the files blockMeshDict file defining turbulenceProperties.
From OpenFOAM v3.0, the blockMeshDict file is located inside the system folder and turbulence properties is defined using the file turbulenceProperties located in constant folder.
The version of ubuntu doesn't matter until the OpenFOAM version you are using works in it.
