    Lucid kernels not being presented for installation

    Just curious as to why this would be happening, but I had been running on the Lucid kernel 2.6.32-28-generic.
    And when I looked in Synaptic, I noticed there were kernels 29 and 30 available.

    I manually installed them and deleted the older ones I had - 27 and 28.

    I believe I have all of the generic Lucid software sources and I get updates for everything else.
    Just curious as to why these kernels were not available to be installed automatically.

    I have never seen this happen before.
    Any explanation as always is much appreciated.

    I want to say those are from maverick's backports and not considered an upgrade. I could be wrong, though.

    Re: Lucid kernels not being presented for installation

    They aren't backports, but they are a different package and not an updated version of a package you already have. This is to enable you to have multiple kernels installed, and also to avoid trashing your whole system by replacing a working kernel with one that might not work.

    yeah normally the kernel updates come 'linux-image-generic', if i'm not mistaken. it's all coming together now 0_o lol

    Re: Lucid kernels not being presented for installation

    AFAIK this is the default kernel for Lucid. I initially had
    linux-headers-2.6.32-26
    linux-headers-2.6.32-26-generic and
    linux-image-2.6.32-26-generic
    as the parts of the kernel and then that was updated to 32-27.

    I did notice I had
    linux-headers-2.6.32-30
    linux-headers-2.6.32-30-generic
    But not linux-image-2.6.32-30-generic so I removed them before manually re-installing all 3 files.
    Which is why I was running 32-28 instead of 32-30 (the latest).

    I had gotten an automatic upgrade to a kernel before, which is why I was wondering why I didn't get the 32-29 kernel.

    So, if I make 10_linux executable in grub, with this command:
    Code:
    grep menuentry /boot/grub/grub.cfg | cut -b 1-11 --complement | cut -d "'" -f1 | cut -d "\"" -f 1 | nl --starting-line-number=0
    I get these options: (Both kernels I installed manually)

    Code:
         0	Ubuntu Lucid Lynx
         1	Ubuntu Lucid Lynx (Recovery Mode)
         2	Windows 7
         3	Ubuntu, with Linux 2.6.32-30-generic
         4	Ubuntu, with Linux 2.6.32-30-generic (recovery mode)
         5	Ubuntu, with Linux 2.6.32-29-generic
         6	Ubuntu, with Linux 2.6.32-29-generic (recovery mode)

    Ironically, I got the 2.6.32-31 kernel upgrade today...

    Re: Lucid kernels not being presented for installation

    I got the linux-headers-2.6.32-34 kernel today along with version 7.0.1 of FF.
    But, again for some odd reason I had to go to SPM to find the missing piece and install it from there.
    Prior to doing so, the 34 kernel did not show up and no restart was needed.
    But, all is well now. After I installed the missing piece from SPM, I could see that it built my nVidia driver
    (had to click on show details to see the "SUCCESS") and a reboot was required.

    Just glad I knew what to do.
    Now I'm going to check if my nVidia driver needs updating.
    Which will require the kernels to be removed and then reinstalled.
    Still loving Ubuntu!

    Re: Lucid kernels not being presented for installation

    You've probably removed one of the Linux meta-packages - linux-image, probably.

    As has already been said, kernel packages are classed as different packages rather than different versions of the same package so that you can keep the old one when you install the new (so that your computer remains bootable if the upgrade goes horribly wrong). So that you get upgrades there are a set of meta-packages whose only role is to depend on the latest version.

    Grub should be updated automatically by the install scripts. You shouldn't need to do it yourself.
    None but ourselves can free our minds

    Actually, I didn't remove anything. It has been doing this for the past few kernel installs. I have to go find the missing piece.
    After the updates occurred, Grub did not update or anything and I was left running on the 33 kernel.

    I do see in SPM under Missing Recommends - linux-headers-generic
    We'll see upon the next kernel install if adding that fixes the problem.

    Thanks CatKiller

    In addition to that, definitely make sure that the meta-package "linux-image-generic" is installed as well, as already indicated twice before!

    Greetings.
