I am using Ubuntu 16.04 and I am stuck into blue screen with no message. Its just showing a cursor nothing else. booting Screenshot

Any help is appreciated.

  • This does not look like a Ubuntu 16.04 without extensive changes. Please add additional info to your question on how you changed your base install. Oct 19, 2016 at 20:24
  • It is ubuntu 16.04 this screen appears after the boot process Oct 20, 2016 at 2:06
  • In my case the issue popped up after installing skypeforlinux (from a .deb package downloaded from skype.com). Switching to a character terminal, uninstalling it and then rebooting took me back to the previous (working) state.

I fixed this by rebooting. At the login screen, I switched to a terminal ctrl+alt+F1 and then running sudo apt-get upgrade. That would not run, but I was told to use sudo dpkg --configure -a. After I ran sudo dpkg --configure -a, then I ran sudo apt-get upgrade. Lastly, I ran reboot. This solved the problem.

    ctrl + alt + F3 did the trick for me, then dpkg fixed the problem for me.

This happened to me a couple days ago. I waited until it said it had internal error, and I hard rebooted it (holding down power button).

On Ubuntu bootup, you have your OS selection screen. It's a purple screen showing your possible options for bootup. Use the arrow keys and goto Advanced Options for Ubuntu.

And then select: Ubuntu, with Linux 4.4.0-31-generic (recovery mode)

It'll run a lot of code until you reach a link screen.

Do the fsck option, and it should clean and fix your OS, and do the dpkg option. It will repair the packages. And then reboot. This fixed mine.

And then if you want you can do clean to free up some space

Hope this helps, Dallin

  • Great, this worked for me in Ubuntu 16.04

  • This does not work for segfault error 6 in libnvidia-glcore.so in Compiz.
