there two ways to do that
First way you can do it by terminal just copy this command and drop it in your terminal
update-manager -d
Second way is by doing it by yourself "and i prefer this method at least you know what you are doing so you can avoid some mistakes "
1- Open Update Manager from either the Power Menu or the Dash.
2- Click the ‘Settings’ button in the lower-left corner of the Update Manager window:
3- This will open Software Sources.
4- Click the menu next to “Notify me of a new Ubuntu version” and select ‘For Any New Version’.
5- Once you’ve made the change you will likely be prompted to input your user password.
After this, close Software Sources, then close and then reopen Update Manager.
6- You’ll now see the following prompt displayed at the top of the window of update Manager
Important Note :
* It also pays to back-up any important files and folders before upgrade.
Open a terminal and run the following command:
update-manager -d
