How to upgrade from 18.04 to 20.04?

ng flag

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?

I don't know if there is such a thing as "the best way". You might want to rephrase it.

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.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
