I'm having no luck upgrading my Ubuntu 18.04 to 20.04. At every attempt, the upgrade process is interrupted with this message:

You can download the iso of Ubuntu 22.04, and flash it to a USB drive, and install it.

Ubuntu 18.04 LTS has reached end of standard support in May 2023. This means it can't be upgraded to 20.04 in the normal way. See the link below for how to upgrade from an obsolete version of Ubuntu.

Does this answer your question? [How to install software or upgrade from an old unsupported release?](https://askubuntu.com/questions/91815/how-to-install-software-or-upgrade-from-an-old-unsupported-release)

Does 18.04 qualify as a 'very old Ubuntu', really? The topic you've linked seems to mostly refer to actually ancient versions, like 9.04.

@kubakonrad the same applies to any out-of-support versions. 18.04 is older now than 9.04 was when the question was written.

You don't seem to have any bionic-updates sources, nor any bionic-security sources. Those are required for a properly-functioning Ubuntu system.

That is the most likely cause of your current problem. Turn those back on, install the mountain of updates thence, and then try your release-upgrade again.

Those sources don't get turned off automatically. A human did that.

The lack of security updates may be a serious problem: Were you on my network, you would be required to do a full wipe-and-reinstall. If you don't recall how or why those sources were disabled, then a reinstall might be a very good idea.

It doesn't matter because the OP is trying to upgrade to Ubuntu 20.04 from it.

@user535733 I did not turn off anything: https://ibb.co/Q9RJqg6

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.
