Hello Bernard856,

It may be just a temporary occurrence of such an error and therefore I will advise that you wait for sometime and then try running the update again and see if it will work. Maybe the latest update has not been posted to the Ubuntu site yet and trying later may work.

You should also just check your internet connection one more time and verify that it is indeed strong enough. If you have queued any downloads pause them, and if you have opened many tabs in the browser you are using close them because they may be taking up a lot of bandwidth hence making the download of the update unsuccessful.

Hope this helps.
