Yesterday I was watching a video on youtube and suddenly my laptop got frozen.
I wasn't able to even move my cursor, so I gave it 10 min and after no response, I pressed the shutdown button for 5 seconds and rebooted my machine.

When it rebooted, it presented me the following screen: enter image description here

Since than I've been searching the internet for any way to get pass this with absolute no luck.

Bellow I'll leave all the steps I've tried so far:
[First I was having problems enabling networking so these were the steps that helped me:]

  • selecting the option Advanced options for Ubuntu

enter image description here

  • choosing the option Ubuntu, with Linux 4.4.0-66-generic (recover mode) enter image description here
  • selecting the option Enable networking from the Recovery Menu

enter image description here

  • when it finishes and returns to the Recovery Menu, I select the option Drop to root shell prompt

  • and then running the following commands with my Ethernet cable plugged in did the trick:

Commands:

/etc/init.d/networking start
echo "nameserver 8.8.8.8" > /etc/resolv.conf

Then I followed this answer referring to this link and repeated the commands for about 10 times each in random order as described in the post:

apt-get update
dpkg --configure -a
apt-get dist-upgrade
apt-get -f install

And I also tried this: answer

cd /etc/dhcp/dhclient-enter-hooks.d
sudo rm debug
sudo ln -s ../debug.dbkg-new debug
cd /etc/dhcp/dhclient-exit-hooks.d
sudo rm debug
sudo ln -s ../debug.dbkg-new debug

After all of that, my machine is still showing the screen in the first image. At this point I don't know what more can I try so I really need some light on this.

Don't know if this is relevant but this is my uname -a:

Linux rm-pc 4.4.0-66-generic #87-Ubuntu SMP Fri Mar 3 15:29:05 UTC 2017 x86_64 x86_64 GNU/Linux

Also when I executed journalctl -xb and this are all the red lines in the code: enter image description here enter image description here enter image description here

  • Turn off secure boot in your BIOS. You've got a problem in your /etc/fstab file. Paste a copy into your question and we can take a look. And DON'T manually edit /etc/resolv.conf (it says that right in the file!).

I had this same issue. I had to go into the recovery mode for the 64 Kernel (65 was showing but it wouldn't let me do the apt-get update even after enabling networking) then enabling networking. Then I did an apt-get update and the dpkg --configure -a.

It stalled in the middle of that showing Loading Braille support... I had to press Ctrl+Z to get out of it and then do it again to finish. I think I did this 3 times before it finished unpacking and installing the 66 Kernel.

Once that was done I was able to boot it fine. Once in the GUI I was able to do another apt-get update, dpkg --configure -a and everything was fine. I also ran apt-get autoremove to get rid of all the old kernels. I'm back up again!
