After updating my ubuntu via update manager i received the following message

#The voume "boot" has only 6.2 Mb left"

How can I free space in the Boot volume?
Thanks

Let's see the output of
sudo fdisk -l in terminal to see what partitions you have. Do you know if you have a separarte /boot partition?

not too sure what to make of this, but here you are:

This doesn't look like a partition table
Probably you selected the wrong device.

yes i belive my boot partion is seperat.

It's difficult to be sure as you have so many disks, one of which, sdb, is formatted using GPT partition(s). However, it looks as if sda1 may be your /boot partition. Can you boot to ubuntu, or use a live system if that is a problem, install gparted and then show us screenshots of the gparted window for each separate disk, as that will show how fully used each partition is, and perhaps give a clue to which is your problem partition. The output of
sudo parted -l
mount may also help.

[gordintoronto]

At boot time, select the option which will display all the kernel versions you have installed. Write down on a piece of paper enough that you can search for each one, for Ubuntu 12.04 this might be:
0-38
0-39
0-42
etc.

Press ESC to get back to the first Grub menu, and boot into the latest kernel.

Install Synaptic Package Manager. Run Synaptic, and search for "0-38" or whatever your oldest kernel is. It should display about a dozen results, three of which are installed. For those, select "completely remove." Then Apply. Keep the latest two or three kernels, get rid of all the others. Finally, open Terminal and enter this command:
sudo update-grub

[ajgreeny]

You can easily see what kernel versions you have installed with command
grep "menuentry " /boot/grub/grub.cfg | cut -c 1-100 and then completely remove the old ones using synaptic, leaving just two numbered versions, similar to what gordintoronto said. My command simply means there is no need to reboot or look for the installed kernels in the menu at boot time.

when i look at Synaptic for one of the numbers i get the folloiwng screen:

244201

now do i chose remove or permenantly remove?
do I click on eache of the highlithed itemens? or just the generic ones.
kind of nervous about removing this :)

advice apreciated.

[efflandt]

For now search "linux" in synaptic and mark to Remove any linux-image-generic and Completely remove any linux-headers (which also removes same version linux-headers-generic) for any version that is 3.2.0-40 or lower. Once you are able to install most recent kernel (mine is 3.2.0-48) you could also remove the 0.41 version if you want to. Just keep 1 or 2 old kernel versions in case a new version does not work for some reason (never had that problem). That should automatically update-grub unless with so many drives you are booting from a different grub (in which case you may need to sudo update-grub for that one).

[gordintoronto]

For the displayed screen. you can "completely remove" all three of the installed files. By my count, you can get rid of 20 old versions. probably three files each, totalling about 5 GB of disk space in your root partition. (It will save space in Boot, but I don't know how much.) Then run: sudo update-grub

As efflandt said, you can then install 3.2.0-48.

Worked like a charme.
