Error 927 while updating YouTube

I am suddenly getting Error 927 while updating the YouTube App from Official Google Play Store on my Android device.

Android version: 4.2 and Device name: Micromax Canvas 4

I am using 2G Internet connection and even the coverage is sub-optimal. I am using the same device since last 2 years and never saw this issue in past. Also, this issue I am seeing coming only for Updating YouTube App.

For other App's update, there is no problem.
