Whenever I start Ubuntu (running via VMWare), the boot process gets stuck at
Stopping System V runlevel compatibility
I browsed through many answers here and elsewhere, but they mention going into tty1 using Ctrl+Alt+F1. However, the combination of Ctrl+Alt+F(1-9) doesn't seem to work, because there is no change in the screen contents. All I can see are the displayed boot commands. So how do I resolve this error? Please note that I am unable to get past this screen, so cannot make any changes in Ubuntu's files via the terminal.
Edit: Not a duplicate question, because the suggested approaches (of going into tty1) don't work.
