I updated from 13.04 to 13.10 but
uname -r still says I am on 3.8.0-31-generic.
How can i fix this and get 3.11 or 3.12 ?
Happened exactly the same, I noticed that now that I had to compile wacom drivers. For whichever reason, the package
linux-image-generic was not installed (probably ocurred during the upgrade from 13.04 to 13.10).
sudo apt-get install linux-image-generic
seems to correct the fact (will modify this if not).
You can also do
sudo apt-get install linux-generic
to automatically install the kernel headers, too (thanks to Lars Nyström).
(obviously if you have -rt or -lowlatency kernels you have to adapt this to your case)
I downloaded the 3.12 rc6 kernel deb files from kernel.ubuntu.com and installed it with
You need to first enable the proposed repositories
Then enable all 4 update sources and on the Ubuntu Software tab enable all 4 options also. Then update and you should see the 3.11.X
Do not update to the 3.12.X or the 3.13.X without knowing that you will find weird behaviors related to drivers, boot time and graphical issues. Always use the one in the updates by Ubuntu.
