Recently, I run an update for my Ubuntu system that totally messed up my system. Neither graphics driver nor mouse driver nor WLAN driver are recognized. That means I don't have any Internet connection either.

Is there a way out of this mess without re-installing my OS?

  • What update did you run? – Organic Marble Oct 16 '15 at 15:09
  • @OrganicMarble : A list of updates that was recommended by the system. It. I believe I got the error “Package is in a very bad inconsistent state”, but I'm not entirely sure. – John Slegers Oct 16 '15 at 15:11
  • @JohnSlegers, do you have LAN working? – Aizuddin Zali Oct 16 '15 at 15:15
  • @AizuddinZali : Nope. – John Slegers Oct 16 '15 at 15:17
  • @JohnSlegers if you having any means of network connection then we might try apt-undo. At this stage I bet installation recovery is the best option. – Aizuddin Zali Oct 16 '15 at 15:18
  • @AizuddinZali : I'm afraid I will need to fix the drivers first before I'll be able to connect to the Internet. – John Slegers Oct 16 '15 at 15:21

    Try changing to an older kernel, in GRUB choose `advanced options for Ubuntu` and pick the one before the latest one. Drivers are part of the kernel, should get you going again. – Mark Kirby Oct 16 '15 at 15:59

Thanks to mark kirby's suggestion, I managed to fix the problem.

What I did to fix my problem :

  1. In GRUB, I selected advanced options for Ubuntu and picked the kernel before the latest one and loaded that kernel.

  2. I updated my packages using sudo apt-get update.

  3. I cleaned the downloaded packages using sudo apt-get clean.

  4. I removed unneeded packages using sudo apt-get autoremove.

  5. I reconfigured all packages using sudo dpkg --configure -a.

  6. I fixed broken packages using sudo apt-get install -f.

  7. I removed the latest kernel using sudo apt-get purge linux-image-x.x.x-x-generic.

  8. I updated my GRUB using sudo update-grub2.

  9. I rebooted my system.
