Get back your privilege for your Ubuntu.

Recently, I lost my sudo privilege for linux system, which make me feel panic. I don't want to reinstall the system again. I got no time to do this.
However, I was lucky enough to find a solution.

In fact it is easy. Restart the system and select recovery mode from grub menu.

Next step, just select fsck so that you can mount / as a writeable directory.

When you finish the step above, select enter the system as root.

sudo addgroup your-username sudo

Now you are fine.
