I followed the command in this question to upgrade my Ubuntu kernel to 3.5

I entered the command and reboot after installation:

sudo apt-get install linux-image-generic-lts-quantal

And after rebooting, I found the kernel is still 3.2.0.

enter image description here

After that, I tried apt-cache search linux-image-3.5.0 and sudo apt-get install linux-image-3.5.0-37-generic. The messages showed that no new installation needed.

For your information, this is my laptop spesification:

  • ASUS A53S with Intel® Core™ i7 CPU 2670QM @ 2.2GHz
  • 8GB memory
  • nVidia GeForce GT630M

I am not sure if I can upgrade from installing the debs, and suggestions?

EDIT:

I tried sudo update-grub, and I still cannot see Ubuntu 3.5.0-37 in my grub menu.I also checked grub advanced options for Ubuntu, 3.2.0-49 & 3.5.0-36 & 3.5.0-37 do not exist.

try updating grub

sudo update-grub

edit: did you try reinstalling?

sudo apt-get install --reinstall linux-image-generic-lts-quantal
grub-mkconfig -o /boot/grub/grub.cfg

i googled and found that two os may cause this problem so if ubuntu 12.04 is not your default OS, change your default OS to ubuntu 12.04.
