Trying to upgrade to a new release version, having trouble with /etc/apt/sources.list
I am trying to upgrade to a new release version following the instructions of the accepted answer here.
Someone mentioned in the comments section of the OP’s question that you should change http://old-releases.ubuntu.com/ubuntu/ to http://us.archive.ubuntu.com/ubuntu/
so that’s what I did. The current state of my sources.list file is as shown below.
When I try to run sudo apt-get update && sudo apt-get dist-upgrade, I get
