I am on Ubuntu 20.04.4 LTS and the Software Updater suggests me to upgrade my Ubuntu to 22.04.1 LTS. I click the Upgrade... button and nothing happens. What might be the problem in your opinion?

Software Updater. The software on this computer is up to date. However, Ubuntu 22.04.1 LTS is now available(you have 20.04). Settings... Upgrade... OK

    Run do-release-upgrade in a terminal and you'll see what is going on. – Pilot6 Aug 15 '22 at 07:33
  • It says "Please install all available updates for your release before upgrading." but I don't have any other thing to update in the "Software Updater". – ilhan Aug 15 '22 at 07:38
  • I have one application update' code20 (20220729) but when I click it it says "Unable to update core20: snap has no updates available". – ilhan Aug 15 '22 at 07:39
  • After restart I don't have any Ubuntu Software or application updates. – ilhan Aug 15 '22 at 07:42

The first Ubuntu 22.04 point release has just been released, and many Ubuntu 20.04 users are trying to upgrade to Ubuntu 22.04 at the same time. There may be a temporary connectivity issue with your update server. Try waiting and clicking the Upgrade... button again in another 24 hours.

    This answer might have made sense when you made it, but I encountered the same issue right now. Also, if there is a connectivity issue, why is there no error message? Presumably if things are working properly, it would test for the connection and if the connection timed out there would be an error message. Clearly something is not working as intended. – cazort Sep 14 '23 at 16:52

I had exactly the same thing trying to upgrade to 23.10 from 23.04. Clicking on the Upgrade button would just close the dialog and nothing would happen. In the end, doing Pilot6's suggestion is the correct method.

First, using terminal, install update manager:

sudo apt install update-manager-core

Then, start the upgrade process:

sudo do-release-upgrade

This then showed the upgrade instead of just a blank screen. :)
