Recently, I had a kernel panic and had to do a hard shutdown. On the next boot, I updated Ubuntu 14.04 using
sudo apt-get update .
Following that I rebooted the system using sudo reboot as described in the answer. Generally, I reboot/restart using the GUI - clicking the shutdown button and choosing reboot/restart. Now I have been waiting for last 15 minutes and Ubuntu is still booting.
That makes me wonder if there is a difference between rebooting using the terminal vs rebooting using the GUI. My next question is should(can) I interrupt Ubuntu if it has been trying to reboot for a long time? If yes, then how (kindly mention all the required steps)?
Helpful links - Is there a difference between reboot, init0, etc
