She tried sudo apt-get install again. It worked.
When the screen glowed back to life, she reopened her terminal. One innocent sudo apt-get upgrade later, the terminal spat out: Dpkg Was Interrupted You Must Manually Run Sudo Dpkg
She typed:
sudo dpkg --configure -a The terminal hummed for a second, finished configuring whatever package had been interrupted mid-step, and returned her to a clean prompt. She tried sudo apt-get install again
So she read it literally. You must manually run: sudo dpkg --configure -a That’s it. No secret dance. No reinstall Ubuntu. Just a single command. Dpkg Was Interrupted You Must Manually Run Sudo Dpkg
