How to set up a Wi-Fi hot-spot on Ubuntu 17.04?

Question

I recently upgraded from Ubuntu 16.10 to 17.04. In Ubuntu 16.10, I could setup a WiFi hot-spot to give Internet access to my Android phone using the trick mentioned in this article Share internet with Android Ubuntu 14.04. I can connect to WiFi now using the fix mentioned in answer to this question: Can't connect to wifi on Ubuntu 17.04.

But when I click on "Connect to Hidden WiFi Network" and choose to start the hot-spot setup, I see this notification and it doesn't start.

How should I resolve this?

1. If Hotspot is on then turn it off first. Go to System Settings > Network

   Click Edit Connections

   Select Hotspot then click Edit
