So i had to roll back to andriod. ubunut is not realy ready for my phone.
So this is how you do.
1. download you andriod images from here
https://developers.google.com/android/nexus/images#nakasi
Download and untar in nice folder.
2. Connect with USB to phone and power it on (Booting to ubuntu is ok)
run
adb reboot-bootloader
This will make the phone go into boot image.
3. Install andriod
in the folder that the downloadin andriod image is in run
sudo ./flash-all.sh
4. All Done
So now you have you phone back to running andriod. You can look down the boot images but i did not 🙂
