    Does this answer your question? [How can I fix a 404 Error when using a PPA or updating my package lists?](https://askubuntu.com/questions/65911/how-can-i-fix-a-404-error-when-using-a-ppa-or-updating-my-package-lists) and [How can I fix apt error "W: Target Packages ... is configured multiple times"?](https://askubuntu.com/q/760896/) – karel Jan 23 '23 at 17:41
  • Title is incorrect - you are trying to update from 18.x to 20.x, and not in reverse – User1986 Jan 23 '23 at 17:54

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.
