So i have 3.13.0-34 & 3.13.0-33 & 3.13.0-24 all installed but the system constantly sticks with 3.13.0-24.

update-grub does not seem to change this. grub configuration says boot entry 0. I'm at a bit of a loss what to do next but want to keep my kernel updated when I do a dist-upgrade, currently it installs the newer kernel packages but never uses anything but 3.13.0-24.

The output of uname -a.

$ uname -a
Linux <hostname> 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

The contents of /boot.

$ ls /boot

initrd.img-3.13.0-33-generic  vmlinuz-3.13.0-34-generic

Here is the grub.cfg info requested.

$ grep Ubuntu /boot/grub/grub.cfg

and the output of "sudo update-grub".

Can you confirm that all three versions are present in the output of grep Ubuntu /boot/grub/grub.cfg? –  Oli Aug 18 at 10:19
    
Added requested output to the question because the comment mangled the output. –  Andy Barnes Aug 18 at 10:28

That's great. Unfortunately (for the purposes of diagnostics) that all looks normal. Two more ideas though. Are you sure you've done a proper reboot since installing those? A lot of people hibernate without thinking about it and some things (like the crashkernel setup) hotwire the reboot sequence so you never get back to grub. Do a proper shutdown, power off and start up. Failing that, what happens if you manually select the latest version at the grub screen (hold left shift while booting)? –  Oli Aug 18 at 10:42

What about manual interactive selection? –  Oli Aug 18 at 10:48

It turns out that the hosting company I use (Digital Ocean) have a control panel through their website that allows you to set the kernel. It also appears that their site does not in any way respect the OS choices made about which kernel the system will boot.

Resolved by choosing kernel through their control panel. This is only affecting my droplets on their service, not live local machines (tested and confirmed).
