I wanted to upgrade my Ubuntu 16.04 to 20.04. As a part of the process I upgraded it first to 18.04. Then I tried all of the following methods but the upgrade didn't happen.

Method 1software updater

I tried clicking Upgrade, but nothing happened. So I followed this tutorial .

Method 2

sudo do-release-upgrade

I got the following error

Checking for a new Ubuntu release
Please install all available updates for your release before upgrading.

Method 3

sudo do-release-upgrade -d

I got the following error

Checking for a new Ubuntu release
Upgrades to the development release are only
available from the latest supported release.

I have updated the packages in my machine multiple times, yet I keep getting these errors and cannot upgrade to 20.04. Can someone explain why this is happening and how to solve it. Please note that I'm currently using a x86_64 distribution.

Thanks in advance.
