Upgrading Ubuntu Subsystem in Windows 10

We can upgrade the Ubuntu version of the Linux subsystem in a Windows 10 machine. This post assumes that a current Ubuntu subsystem is installed on your Windows 10 machine.

Here are the steps
Run bash  (I ran via Powershell)
Check version with Command  lsb_release -a

 Use the upgrade command sudo do-release-upgrade
 
Continue by pressing 'y' on the Keyboard. It will make a while to download and Install.
Occasional Dialog comes out from time to time

Restart is required. Press 'y' from the keyboard when ready.

Check Version again after upgrade is completed
