This is by far the best answer in my opinion:
http://tuxtweaks.com/2010/10/remove-old-kernels-in-ubuntu-with-one-command/
Follows the last command on the site above:
dpkg -l linux-* | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e [0-9] | xargs sudo apt-get -y purge

You can also boot the server in rescue mode, and reinstall only the grub

Hit same problem here with Ubuntu 13.04 last month. At the time, upgrading to VMWare player 5.0.2 build-1031769 solved the problem. Fast forward a month, hit a new problem today after recent 13.04 updates, again VMWare would not start. Latest VM player version is still 5.0.2. Google lead me to this explanation:

The pf-kernel includes patches to the Linux kernel which means task scheduling, process management, memory management, and SSD caching. Most of the improvements have nothing to do with the speed of your hard drive but rather how the operating system handles the applications running on your computer. They're designed to make the system more efficient, which ...

According to the Ubuntu X team's R-series LTS backport page,
The official hardware enablement stack will be officially released as part of the 12.04.3 update.
And according to the Precise Pangolin Release Schedule, this will happen on 15 August 2013.
The upgrade policy around this is shown under the Kernel/LTSEnablementStack page.

I found what this problem was.
The issue was that, when I upgraded Ubuntu, by installing through a liveUSB instead of doing a normal upgrade, it left behind the old kernel files in the /boot folder.
Now that I have upgraded in the same way from 12.10 to 13.04, I encountered the same situation.
The solution is to manually delete all the files related to ...

I've posted this quote to help future visitors. The OP wrote this in his question:
I downgraded to the 3.8 kernel and the sound is working again, so I'm
sure it's the kernel that's causing that (even though I didn't get any
error while installing it).

Turned out to be dead simple.
$update-grub
found the newer kernels and set the latest one as the default.
Now all I have to do is remove the old ones.
Plenty on documentation on that subject.
Thanks for all the pointer.

You could add system ("sudo apt-get remove $(dpkg -l|egrep '^ii linux-(im|he)'|awk '{print $2}'|grep -v `uname -r`)"); to some line in the apt source code for upgrading packages.
Alternatively, just make a script called aptupgrade and paste this in it:
sudo apt-get remove $(dpkg -l|egrep '^ii linux-(im|he)'|awk '{print $2}'|grep -v `uname -r`); sudo ...

file only tells you the architecture of binaries. There are cases where a kernel has or uses a different "bitness" userspace (SPARCv9, ARM Thumb), so this cannot be considered accurate.
Only uname gives you direct information about the currently running kernel, therefore you are running a 64-bit kernel.

You can see the programs installed are on their 64-bit version, so I assume it's a 64-bit system.

It looks like the main issue with vmware workstation on 13.04 is compiling modules like vmci.ko. The easiest way to get these is to do apt-get install open-vm-dkms. This installs vmci.ko, and friends.

Per the Ubuntu VMWare Player install page, use
sudo apt-get install build-essential linux-headers-$(uname -r)
to install the headers. Then, you can either let it install or you can uninstall and reinstall vmware player.

I just had the same problem. The only thing that helped was manually removing enough files in /boot using

for
apt-get -f install
to be able to complete normally. Then use
dpkg --list|grep linux-image

To the contrary: Every kernel needs space on your hard drive.
But you can just boot one kernel even if multiples are installed.
If you install another kernel in Ubuntu you install a newer version. The old one isn't removed automatically because it is sometimes useful for recovery.
If you want to remove the old ones, you have first to list all the kernel ...

There are three kinds of drivers:
tested and stable drivers
tested and presumably stable drivers

If you look at the man page for make with $ man make, it explains a little more. The -j flag, when followed by a number, restricts the number of processes running at one time to whatever you put. However, if -j is not followed by a number, the number of threads is not limited. I think since it was executing so many threads at one time, it hosed things up. As ...

It would not be safe to remove AppArmor in the sense of the word. You would be disabling a security system designed to be in place for protecting you. So it would indeed make you less safe. What you want to know is: yes you can remove it without side-effects but lessen that system's security with it.
But the changes to apparmor are quite minimal, if you ...

I have the same issue when compiling the kernel for zynq.
This is what I used:
make -j ARCH=arm UIMAGE_LOADADDR=0x8000 uImage
Now I change it into:
make ARCH=arm
and it compiles and creates the Image and zImage in the \arch\arm\boot\
Goodluck

This fixed it for me on Ubuntu 13.04:
sudo modprobe drm_kms_helper
echo N> /sys/module/drm_kms_helper/parameters/poll
Apparently the drm_kms_helper module isn't loaded by default on 13.04? You may have to load it in your /etc/modprobe.d/ and then sett the poll parameter.

Looks like a major breakage to me. There are meta-packages that don't work at all, some link to the old 3.2.0 kernel.
For example, doing apt-get source linux-image-$(uname -r) will fail, as it tries to use linux-lts-quantal instead, and then fails as that package cannot be found. We've been trying around for two hours, before resorting to using their kernel ...

If instead of
#include "linux/config.h"
writing:

I installed the suggested packages as above, but it still gave me the same error. Installing the latest VMWare Player solved the problem.

You can remove AppArmor without immediately killing the system. Nothing relies on it to function.
But it is there for a reason. If security really isn't a concern, that's fair enough, but if you're just doing it for a quick convenience, consider learning how to adapt the rules.

I had the exact same problem when I upgraded from 12.10 to 13.04. When I started VMware I would get the same message:

It seems that this error can be ignored and after a restart the nvidia driver will be correctly loaded.

I believe the issue is that you have the wrong kernel headers, it looks like one of those suggestions is trying to use kernel headers for 3.9.0, doesn't 13.04 use kernel version 3.88 ? Try getting the kernel headers from apt, do:
sudo apt-get install linux-headers-$(uname -r) (borrowed from nixCraft)
and then try to install it again

Yes it is possible, but it might be a hassle in some cases.
If you just installed the base OS, using a text based log-in (no display drivers needed), make sure that the kernel has all the drivers for both systems (netwokr drivers etc) and that both use the same disk controller (e.g. both using SATA or eSATA) then this should work fine. Just pull the SSD ...

Boy! you have one hell of a configuration.... Thumbs up to that. Have you tried more stable Ubuntu 12.04 LTS. 12.10 is buggy on most computers or you can try 13.04 which is much stable than 12.10.

When creating a VM using VirtualBox, the first screen you are presented with asks for the name of your new VM and attempts to auto-detect which operating system you're installing. Make sure that you select Ubuntu (64 bit) in the OS drop-down menu. Just selecting Ubuntu in that menu will result in the error you have described.

In general, kernel modules have to be built for the current kernel and not simply copied.
If you need a custom module, either file a bug report or consider building a custom kernel.

Make sure that the following lines are intact in your /etc/sudoers file
Defaults env_reset

After the reboot, you wont be facing this problem.
