    new kernel vsn caused dkms failure, depmod error

    Did a clean install of Kubuntu 12.04 two days ago.
    This evening it said there were available updates, namely kernel version 3.2.0-31. In more detail:
    Code:
    The following NEW packages will be installed:
      linux-headers-3.2.0-31{a} [3.2.0-31.50]  linux-headers-3.2.0-31-generic{a} [3.2.0-31.50]  
      linux-image-3.2.0-31-generic{a} [3.2.0-31.50]  
    The following packages will be upgraded:
      linux-generic [3.2.0.30.32 -> 3.2.0.31.34]  linux-headers-generic [3.2.0.30.32 -> 3.2.0.31.34]  
      linux-image-generic [3.2.0.30.32 -> 3.2.0.31.34]  linux-libc-dev [3.2.0-30.48 -> 3.2.0-31.50]  
    The following packages are SUGGESTED but will NOT be installed:
      fdutils  linux-source-3.2.0  linux-tools  
    4 packages upgraded, 3 newly installed, 0 to remove and 0 not upgraded.
    I did the update via
    Code:
    sudo aptitude -v -V safe-upgrade
    and received the error:
    Code:
    run-parts: executing /etc/kernel/postinst.d/dkms 3.2.0-31-generic /boot/vmlinuz-3.2.0-31-generic
    Error! Problems with depmod detected.  Automatically uninstalling this module.
    DKMS: Install Failed (depmod problems).  Module rolled back to built state.
    The full output is attached to this post.

    Being worried, before rebooting I did
    Code:
    sudo apt-get install -f
    sudo apt-get clean
    sudo apt-get update
    sudo apt-get install --reinstall  linux-headers-3.2.0-31  linux-headers-3.2.0-31-generic    linux-image-3.2.0-31-generic
    I then rebooted and system seems to be fine for the moment.

    However i am quite worried that there is something wrong deep in the system and it wil eventually show up. What is the cause of this and what does it mean?

    [this machine is a Dell Precision 670 with Nvidia Quadro FX 1400 graphics card, running NVidia drivers. I am testing 12.04 so not too much else installed on it yet.]

    I had similar problems, Firefox had stated that it couldn't start, so I rebooted, not realizing this had happened. Now the system doesn't boot. Any thoughts on recovery?

    Re: new kernel vsn caused dkms failure, depmod error

    The problem in this thread is that the new kernel vsn caused dkms install failure, due to a depmod error.
    a. the problem is with is with 12.04 only
    b. the system does boot
    c. and firefox is not part of the problem.

    Did you have the error:
    DKMS: Install Failed (depmod problems) ?
    if not, it is not a similar problem.

    Re: new kernel vsn caused dkms failure, depmod error

    Here's my sequence of events. ubuntu 12.04 vm running on 12.04 host (both 64-bit).

    Got the "Not all upgrades can be installed message."

    Did
    Code:
    sudo apt-get update
    sudo apt-get upgrade sudo apt-get install linux-generic linux-headers-generic linux-image-generic
    Got the Error! Problems with depmod blah blah messages as described above.

    Not knowing if this was going to cause problems on reboot, I researched and came across this thread.

    Followed the steps above to fix/clean/update/reinstall (mine was 3.2.0.52 kernal)--no depmod errors.

    Rebooted and all is well.
