Linux Ubuntu 12.04 LTS apt-get not installing new Linux Kernel

Yet for some reason it is getting picked up under their Update Manager. This is for a VM that I'm running in Virtual Box, which I like to update on the weekend.

From Update Manager it is showing the following:

-linux-headers-3.5.0-46 
-linux-headers-3.5.0-46-generic 
-linux-headers-generic-lts-quantal
-linux-image-3.5.0-46-generic 
-linux-image-generic-lts-quantal

From apt-get command line, it is showing the following:

bash$ sudo apt-get upgrade 
Reading packet lists...Done
Building dependency tree
Reading state information...Done 
The following packages have been kept back: 
     linux-headers-generic-lts-quantal linux-image-generic-lts-quantal 
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.

Not sure why the kernel updates are not being picked up by apt-get nor are they getting installed.

The apt-get upgrade command will normally only install updates (or fixes) to currently installed packages.
Typically a new release of Mozilla Firefox, for instance, would be installed with this command.

However apt-get upgrade will NOT generally install new releases, where major changes (including removal of packages or GRUB update is required).
For example, when a new Linux kernel (linux-image-3.x.x-xx-generic, etc.) is available, the package will not get installed.

In order to install the new kernel, you will need to run apt-get dist-upgrade.
You will be notified when you run apt-get upgrade, as it will say that certain packages have been held back.

That's your cue to use: apt-get dist-upgrade.

Have you tried to force the install? Try running "apt-get -f install" after you "apt-get update". For some reason, maybe apt isn't reading the sources correctly? Just a thought. Might work, might not.

***Trashman...I think you hit the nail on the head. I totally forgot that one should run the apt-get dist-upgrade command. Great post!***

Just tried the following

bash$ apt-get force linux-headers-generic-lts-quantal

Nothing. Along with that, don't see force listed under the man page. I guess that was removed. I remember that force was an option awhile back.

That seemed to work.

I've had issues with that command in the past. When I used to run Red Hat (this is before Fedora was created), I would run this for whatever reason and often enough it would break my Linux and I would have to do a fresh install.

Buuuurrrrr..... *road train brakes*
First need to figure out why it's not working the _normal_ way.
Forcing can mess up things like packages not being fully installed and they keep getting stuck when doing "apt-get update" in the future

I did a double look, force is still part of apt-get, however...

--force-yes Force yes. This is a dangerous option that will cause apt-get to continue without prompting if it is doing something potentially harmful. It should not be used except in very special situations. Using --force-yes can potentially destroy your syste
