Is this the best way to get 18.04.6 upgraded to 20.04?

https://www.omgubuntu.co.uk/2020/04/how-to-upgrade-to-ubuntu-20-04

I get these messages when I attempt to upgrade:

$ sudo do-release-upgrade -c

Checking for a new Ubuntu release
Failed to connect to https://changelogs.ubuntu.com/meta-release-lts. Check your Internet connection or proxy settings
There is no development version of an LTS available.
To upgrade to the latest non-LTS develoment release set Prompt=normal in /etc/update-manager/release-upgrades.

Why is it telling me there is no development version available? I want a production LTS version, no interest in a development version. I am able to ping www.google.com so not sure what it's saying about internet proxy settings.

    Move to the next line of your output: Test https://changelogs.ubuntu.com/meta-release-lts in a browser. Does it work? – user535733 Feb 23 '22 at 02:55
  • I don't know if there is such a thing as "the best way". You might want to rephrase it. – mikewhatever Feb 23 '22 at 04:22

    I'd always recommend reading the release notes for the release you're going to (ie. https://wiki.ubuntu.com/FocalFossa/ReleaseNotes) where you'll see an "Upgrading from Ubuntu 18.04 LTS or 19.10" section. – guiverc Feb 23 '22 at 05:54
