Why is my Nexus 5 crashing during 4.4.4 update?

[AC Question]

When I try to update my Nexus 5 (update 4.4.4), the phone downloads the update and asks for an "Restart and Install". During the process, the progress bar shows some movement and then the screen displays "Error!" with a dead android on it.

Can anyone suggest something which resolves this issue?

P.S: I already tried factory reset. That didn't help.
