Latest kernel not working

  • 772

Once while I was using Ubuntu everything locked up. I was no longer able to boot vmlinuz-3.8.0-31-generic. When I would try, it would not get past the boot phase.

Fortunately, I am still able to boot vmlinuz-3.8.0-30-generic and work normally.

Is there any way I can restore vmlinuz-3.8.0-31-generic to work again? Any ideas on what caused the problem or how to recover from it in the future?

    You have to re-configure the packages/drivers installed for latest kernel

    It will do nothing but set-up/configure the packages which was meant for your oldest kernel.

    Here is the possible solution

    Follow these steps precisely:

    1. During boot select the Recovery Mode of your latest kernel and start your system in Recovery Mode

    2. Once your system starts in recovery mode chose grub option listed in the menu. It will prompt you to mount your system in read/write mode. Chose yes. After updating grub it will exit and will come back to the menu.

    3. This time chose root and execute following commands to re-configure your packages:

      apt-get autoclean && apt-get autoremove
dpkg --configure -a
dpkg-reconfigure $(dpkg -l | grep xserver | awk '{print $2}' | tr '\n' ' ')
dpkg-reconfigure -a

      dpkg-reconfigure -a would take some time depends upon packages installed in your system. so please wait for it to complete. If it doesn't give any messages means it executes successfully. If it gives any message just note it and post in comment

      dpkg-reconfigure lightdm

      press Tab to highlight Ok and then Enter to exit.

      update-initramfs -u
reboot

    Once your system restarts chose again your latest kernel normal mode and see what happens.. You should not get black-locked screen this time.

    Reply if something goes wrong, or you get any error message in any particular command. Mention the command with the error message.
