The solution that work for me was:

Temporary Fix To get the system to boot:

  1. After turning on your PC, hold the right SHIFT key to get to the GRUB bootloader if your computer uses a BIOS. If your computer uses EFI or UEFI, continuously tap the “ESC” (escape) key after turning on your PC.
  2. Once GRUB is open, press the “e” key to edit the first highlighted entry “Ubuntu”. Move your cursor down to the line that starts with “linux”, and use the right arrow key to find the section with the words “ro quiet splash”.
  3. Add “nomodeset” after these words.
  4. Feel free to remove “quiet” and “splash” for more verbosity to troubleshoot the boot process. Press “CTRL + X” or “F10” to boot.

The system should now boot.

Permanent Fix To permanently resolve the issue:

  1. Once the system has booted using the temporary fix, log in.
  2. Open a terminal window (Applications -> Terminal, or press the “Start” button and type terminal).
  3. Either “su” in to root, or use “sudo” to open your favorite text editor and edit the file “/etc/default/grub” (I use nano which can be install by running “apt install nano”):

nano /etc/default/grub

  1. Locate the line with the variable “GRUB_CMDLINE_LINUX_DEFAULT”, and add “nomodeset” to the variables. Feel free to remove “splash” and “quiet” if you’d like text boot. Here’s an example of my line after editing (yours will look different):

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

  1. Save the file and exit the text editor (CTRL+X to quit, the press “y” and enter to save).
  2. At the bash prompt, execute the following command to regenerate the grub.conf file on the /boot partition from your new default file:

update-grub

  1. Restart your system, it should now boot!

In my case, I had access non-GUI terminal and simply reinstalled ubuntu-desktop:

sudo apt update
sudo apt upgrade
sudo apt autoremove

sudo apt remove ubuntu-desktop
sudo apt autoremove
sudo apt install ubuntu-desktop

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
