I have been encountering some trouble trying to boot 18.04. When I attempt to boot it becomes stuck "Started Hold until boot process finishes up", and ctrl+alt+f1/f2have no effect Following some instructions from the web I have tried booting into recovery mode to run networking and the execute some commands in the root shell. When I run network it freezes at "Flush Journal to Persistent Log". I have tried to fix that but I am quite new to Linux and have not been able to understand it. Any help is appreciated as I don't have the slightest idea of how to fix this. Thanks in advance for your time.

I had the exact same problem after a kernel upgrade. It turned out that my root partition was stuffed so much, it had no free space. I used the advanced mode menu to free up some space and restarted. It just worked afterwards.
