Does this answer your question?

Title is incorrect - you are trying to update from 18.x to 20.x, and not in reverse

I translated the unfamiliar language into something a normal human can understand and found out that it indicates that there are duplicate entries in your /etc/apt/sources.list file. This can happen when you have added multiple repositories or PPAs to the file.

run

sudo nano /etc/apt/sources.list

and then look for duped entries. Remove the duplicates, and then save using ctrl + o. Then update apt using sudo apt-get update

Also, you should check the package architecture that you are trying to update. In this case it is arm64 and the packages are not available. Arm is basically the type of processor your compute thing uses. (Imma assume you got an apple computer, because of the way you phrased your question)

and you ain't got the ARM version of your etc/apt/sources.list file.

You can check the available package for arm64 architecture in the official website of Ubuntu or other trustworthy sources.

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.
