So that wont work for me, what possibility I have in my case? I use kodi to watch live TV with a USB tuner and play videos of a HDD, basically an htpc

Due to a driver problem, I am forced to use Ubuntu server for arm, in other case, I will be solved with openelec or something like that, so I only need to run kodi interface over Ubuntu without Ubuntu GUI to save resources

Then you're in the wrong thread, this is about running without any GUI at all, including Kodi's GUI.

You want OpenELEC. If you have problems running that, you can go the appropriate forums for that.
