updated ubuntu from 12.04 to 14.04, dmesg still says precise

[fengjiahai]

Hi, I upgraded from 12.04 to 14.04 a few months ago, but recently when I checked my linux headers from uname -r, I realised that it's on 3.5.0-52-generic, which apparently is a kernel for 12.04. As a result, I also wasn't able to apt-get the relevant linux headers.

I also tried to verify this using dmesg, which gives:


Linux version 3.5.0-52-generic (buildd@kissel) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #79~precise1-Ubuntu SMP (Ubuntu 3.5.0-52.79~precise1-generic 3.5.7.33)



Is this normal? Should I just grab the header files from another repository or is this a fundamental problem that I should address, by changing kernel or something?
If so, how do I go about changing the kernel?

[v3.xx]

inxi -S

What will that output?

[ajgreeny]

If inxi is not installed, and it did not used to be, show us also the output of
lsb_release -dc && echo "Desktop: $DESKTOP_SESSION" && uname -mrn which will show similar output to the inxi -S command

[v3.xx]

May not even be a bad idea to have a look at your sources.


inxi -r

or


cat /etc/apt/sources.list && ls /etc/apt/sources.list.d/*.list

Possible grub never updated.
Is it a single boot or dual/multi-boot system?

If dual/multi-boot, perhaps grub installed on a different system is the grub in charge, and until that gets updated, it'll always point to the grub setting it has in place.
Meaning it'll keep loading the old kernel.

Currently, though, we are all swinging at random pitches.
