    /boot partition is full

    I've been updating a remote Ubuntu 8.04 LTS server quite frequently, and ended up filling my /boot partition which is only ~240MB. It looks like there are about 11 different versions of kernel updates on that partition, and I want to remove all but the last few to free up space. My only concern is I want to make sure I do it right because this is a remote server and I *need* it to reboot successfully, heh. Is there a program which will automatically "clean up" the /boot partition, or can you suggest what exactly I can/can't remove (and files I should update, like /boot/grub/menu.lst)?

    Code:
    root@numberzero:~# ls -alhR /boot
    /boot:
    total 204M

    Re: /boot partition is full

    You'll need to remove the packages named:
    linux-image-2.6.24-16-server
    linux-image-2.6.24-17-server
    linux-image-2.6.24-18-server
    linux-image-2.6.24-19-server
    linux-image-2.6.24-20-server
    linux-image-2.6.24-21-server
    linux-image-2.6.24-22-server
    linux-image-2.6.24-23-server
    linux-image-2.6.24-24-server
    linux-image-2.6.24-25-server
    linux-image-2.6.24-26-server

    The run <sudo apt-get autoremove> to get rid of dependencies.
    The latest kernel is linux-image-2.6.24-27-server, so leave it be.

    Re: /boot partition is full

    Hello everyone,

    This thread seemed interesting and my package management know-how can do with a little improvement so I decided to google and see if I could fine the exact commands, best commands to use for this job.

    I came up with the following web page, Safely Remove / Delete Old Linux Kernel from a Linux Server - NixCraft, and I tried out the commands there which apply to Ubuntu.
    Code:
    uname -r
    Code:
    sudo dpkg --list 'linux-image*'
    Code:
    sudo apt-get remove linux-image-2.6.31-15-generic
    I was a surprised at how well that last command worked, first it told me what it was about to do and how much disk space that would free, and then when I agreed it did the job and also automatically ran update-grub for me! Cool!
    Code:
    Reading package lists... Done
    Building dependency tree       
    Reading state information... Done
    The following packages will be REMOVED:
      linux-image-2.6.31-15-generic
    0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.
    After this operation, 113MB disk space will be freed.

    Considering the number of times people post in and complain about the length of their boot menus in GRUB2, it's astonishing that this little sequence of commands is not more well known by now.

    EDIT: We can even uninstall a whole bunch of them at the same time,
    Code:
    sudo apt-get remove linux-image-2.6.31-14-generic linux-image-2.6.31-15-generic linux-image-2.6.31-16-generic linux-image-2.6.31-17-generic
    You guys probably already knew these commands but I thought I'd post them here for the benefit of others who may be looking up something in this thread.

    Thanks, I didn't realize just removing the package would clean up and regenerate all the files as well. Seems to be working great!

    Thanks. This is really elegant. You gave me some new tools here.

    Thank you very much for documenting this, as it came VERY handy on my Ubuntu server's boot partition!
    All the best!
