You may need to fix a broken install/update.

If you can get to a command prompt ctrl+alt+F3 and have an internet connection via ethernet or wifi the fix may be trivial.

From the command prompt:

sudo apt update && sudo apt upgrade --fix-missing

Then be sure to install the latest Nvidia drivers from the PPA:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update && sudo apt upgrade

Once all is done, reboot and enjoy.

I have just tried to upgrade my Ubuntu to Ubuntu 18, and at one moment I had to choose if it should install new version of a certain file or keep the old one, and I selected to see the difference. After which, I didn´t know how to close the window and return to upgrade so I pressed Ctrl+X which terminated the process completely.

At first I could continue using Linux without any problems, but after I rebooted, it started making problems.
It shows a black screen where I can move with my mouse, but I can´t do anything else. So I looked up online what I can do about it, and after trying everything with Booting in recovery mode, I have decided to install a new version of Ubuntu, while keeping the old data on the drive. But it seems that was not the solution either.

Any ideas ?

  have you tried adding nomodeset to the end of your grub boot line? askubuntu.com/questions/38780/… Also, could you update question and tell us what video card are you using? Welcome to AskUbuntu!

  hey yes I have tried both nomedeset and nosplash, it show the linux logo as if it is booting up but then just a black screen. I have a NVIDA Geforce 940mx graphic card. I saw that the new instalation created a new partition from which I can boot up normally, but I want to save my data that is why I still try to find a solution for the question

Hey, I have already tried this. It ended up not allowing me to update the graphics drivers.... it was showing missing dependencies.

can you edit your original question with the missing deps output?
