Comment 153 for bug 1268257

Hello everybody !

It happended to me while upgrading from 3.13.0-43 to 3.13.0-44 on a ubuntu 14.04
nvidia module could not build.
I realised that the update didn't upgraded the linux headers and linux headers generic.
So the solution for me was to install the headers (booting from the older kernel) and execute :
sudo apt-get install nvidia-331-uvm --reinstall

Everything now works as a charm !
hope this helps !
