    Confused about Linux Headers

    Hello,

    I'm quite the noob when it comes to getting into the guts of Ubuntu.

    I am ultimately trying to get VirtualBox to work...

    From all the Googling I have done I have found the problem but have no idea how to fix it.

    Apparently the kernel headers are missing from my system. The error that I get is
    Code:
    Error! Your kernel headers for kernel 3.0.0-17-generic cannot be found.
    Please install the linux-headers-3.0.0-17-generic package,
    or use the --kernelsourcedir option to tell DKMS where it's located
    I ran the following command to confirm the kernel that is running.

    Code:
    /etc/init.d$ uname -r
    3.0.0-17-generic
    That looked good.

    I tried to install these headers...
    Code:
    /etc/init.d$ sudo apt-get install linux-headers-$(uname -r) gcc
    Reading package lists... Done
    Building dependency tree       
    Reading state information... Done
    E: Unable to locate package linux-headers-3.0.0-17-generic
    E: Couldn't find any package by regex 'linux-headers-3.0.0-17-generic'
    When I look in Synaptic package manager it is showing that I have 3.2 Linux headers up to 3.2.0-30. OK, this is confusing.

    When I look at the Ubuntu Wiki is says that 12.04 has kernel 3.2.14. Hmmm.

    So I am pretty confused about what to do.

    Any help would be greatly appreciated.

    /Paul

    Re: Confused about Linux Headers

    So I am pretty confused about what to do.
    O.K., well I am also pretty confused as to how to help you.
    I don't see those particular header versions anywhere on the Ubuntu Kernel PPA site
    It sound as though you think you are at 12.04, is that true?
    I wonder (long shot) if you are somehow booting into an old kernel, even though you have newer ones. All I can think of is to ask from more information. First, show us the contents of /boot, Example:
    Code:
    doug@s15:~/sguide-1204/sguide-footnote$ ls -l /boot
    total 115838

    Edit: Oh, and the disto, example:
    Code:
    doug@s15:~/sguide-1204/sguide-footnote$ lsb_release -a
    No LSB modules are available.
    Distributor ID: Ubuntu
    Description:    Ubuntu 12.04.1 LTS
    Release:    12.04
    Codename:   precise
    If it comes it it, we might ask for the contents of /etc/default/grub, but I 'm getting ahead a bit now.

    Re: Confused about Linux Headers

    For whatever reason, it seems that your computer is not loading the current kernel during boot. Have a look at your /etc/default/grub file. Look for this line:
    Code:
    GRUB_DEFAULT=0
    which in your case, I suspect is not set to zero.
    Note that I also like to increase the timeout, in case I want to manaully select another kernel:
    Code:
    GRUB_TIMEOUT=10
    Before you make changes, save the current file, as say grub.bak. You will need sudo to edit the file. After editing you need run:
    Code:
    sudo update-grub
    if you have troubles, post your /etc/default/grub file here.

    Thanks for the direction Doug.

    BTW I heard BC got hit with a 7.7 earthquake. I hope everything is OK. I'm still having issues with this problem and will certainly understand if you drop it due to that terrible disaster.

    I looked for the grub file where you had suggested and it was not there...

    /usr/share/grub
    /usr/share/doc/grub
    /boot/grub
    /etc/bash_completion.d/grub
    I checked all the "grub" out and they were either an executable file or a directory.

    I looked at the /boot/grub directory, which seemed to be the most promising for investigation and was unsure of what was in there.

    Re: Confused about Linux Headers

    Well, the mystery continues...

    Earthquake: Thanks for your concern. Myself, I didn't even notice, but some around here did. It is my understanding that even in Haide Gwaii (A.K.A. Queen Charlotte Islands) area, damage was minimal.

    Yes, /boot/grub should have a file named grub.cfg, which should be a file generated from /etc/default/grub when you run:
    Code:
    sudo update-grub
    So, what is going on in your case? What do you get for this:
    Code:
    doug@s15:~$ dpkg -l | grep grub
    ii  grub-common                               1.99-21ubuntu3.4                           GRand Unified Bootloader (common files)
    ii  grub-gfxpayload-lists                     0.6                                        GRUB gfxpayload blacklist
    ii  grub-pc                                   1.99-21ubuntu3.4                           GRand Unified Bootloader, version 2 (PC/BIOS version)
    ii  grub-pc-bin                               1.99-21ubuntu3.4                           GRand Unified Bootloader, version 2 (PC/BIOS binaries)
    ii  grub2-common                              1.99-21ubuntu3.4                           GRand Unified Bootloader (common files for version 2)
    Is your computer dual boot with some other Operating system? I.E. maybe grub is not your main boot loader thing (which I know nothing about, because I always use grub).

    It looked like the update was the fix but I restarted my machine.
    I don't dual boot.
    It looks like grub is booting the machine.
    I still get the 3.0.0-17-generic when I run uname -r.

    Mystery still continues...

    Re: Confused about Linux Headers

    Hi Paul,

    O.K. I think I might have an idea what is going on. Your computer is using the old menu.lst method for generating the new grub.cfg file.
    I am not familiar with the menu.lst file syntax but if you list here maybe we can figure out a suggested change. I am also not familiar with procedures to possibly update your method, yet maintain any special settings, from the menu.lst method to the /etc/default/grub method.

    Re: Confused about Linux Headers

    Post the content of /boot/grub/menu.lst and we can quickly tell you how to fix this. However I'm a bit concerned about your grub and grub-common packages, as listed a couple of messages back. It shows grub at version 0.97 and grub-common as 1.99; the differences between those versions are extreme since grub underwent a total rewrite a couple of years ago.

    I don't think there's a conflict, though; if there were I doubt that your system would boot at all. I suspect that the grub-common is from a more recent update, while your grub is left over from sometime around 8.04 or even before...

    Doug, the menu.lst syntax will be obvious to you since you're familiar with grub.cfg. It just used direct text editing to do what /etc/default/grub does in the newer versions.

    ## default kernel options for automagic boot options
    ## If you want special options for specific kernels use kopt_x_y_z
    ## where x.y.z is kernel version. Minor versions can be omitted.
    ## e.g. kopt=root=/dev/hda1 ro
    ##      kopt_2_6_8=root=/dev/hdc1 ro
    ##      kopt_2_6_8_2_686=root=/dev/hdc2 ro
    # kopt=root=UUID=c01fb380-878f-40f4-8757-ecd932c2dc9b ro
    
    ## default grub root device
    ## e.g. groot=(hd0,0)
    # groot=c01fb380-878f-40f4-8757-ecd932c2dc9b
    
    ## should update-grub create alternative automagic boot options
    ## e.g. alternative=true
    ##      alternative=false
    # alternative=true
    
    ## should update-grub lock alternative automagic boot options
    ## e.g. lockalternative=true
    ##      lockalternative=false
    # lockalternative=false
    
    ## additional options to use with the default boot option, but not with the
    ## alternatives
    ## e.g. defoptions=vga=791 resume=/dev/hda5
    # defoptions=quiet splash
    
    ## should update-grub lock old automagic boot options
    ## e.g. lockold=false
    ##      lockold=true
    # lockold=false
    
    ## Xen hypervisor options to use with the default Xen boot option
    # xenhopt=
    
    ## Xen Linux kernel options to use with the default Xen boot option
    # xenkopt=console=tty0
    
    ## altoption boot targets option
    ## multiple altoptions lines are allowed
    ## e.g. altoptions=(extra menu suffix) extra boot options
    ##      altoptions=(recovery) single
    # altoptions=(recovery mode) single
    
    ## controls how many kernels should be put into the menu.lst
    ## only counts the first occurence of a kernel, not the
    ## alternative kernel options
    ## e.g. howmany=all
    ##      howmany=7
    # howmany=all
    
    ## specify if running in Xen domU or have grub detect automatically
    ## update-grub will ignore non-xen kernels when running in domU and vice versa
    ## e.g. indomU=detect
    ##      indomU=true
    ##      indomU=false
    # indomU=detect
    
    ## should update-grub create memtest86 boot option
    ## e.g. memtest86=true
    ##      memtest86=false
    # memtest86=true
    
    ## should update-grub adjust the value of the default booted system
    ## can be true or false
    # updatedefaultentry=false
    
    ## should update-grub add savedefault to the default options
    ## can be true or false
    # savedefault=false
    
    ## ## End Default Options ##
