Ubuntu 16.04 – A start job is running for Hold until boot finishes up [Error]

After trying to install the Gnome desktop in my Ubuntu 16.04 I couldn’t boot again my computer after rebooting.

When I pressed ctrl+alt+f2 the message: “A start job is running for Hold until boot finishes up ” appeared.

After a little Google searching I was able to figure out what the problem. It was a problem with Gdm. So I had to use again LightDM.

To fix it:

  • When booting press ESC key to enter in the Grub menu.
  • Start Recovery mode.
  • Select a Root session to be able to execute commands.
  • Mount the filesystem in write mode again:  mount  -o remount, rw /
  • Reconfigure lightdm : dpkg-reconfigure lightdm
  • Reboot

After these steps your computer should boot again.
