    Can't upgrade Ubuntu 18.04 to 20.04

    I'm having trouble upgrading my Ubuntu 18.04. Everytime I try, the process is interrupted with the following message:



    What do I do?

    Support for 18.04 ended in April of this year so you will have to find the correct mirrors for the archived 18.04. Check the site below.

    You may need to install it
    https://ubuntu.pkgs.org/18.04/ubuntu...amd64.deb.html
    Its such an old release

    @ActionParsnip The problem is, when I attempt to install the file, the terminal says:
    ubuntu-minimal is already the newest version (1.417.5)

    and aborts the process. So, according to my CPU, I both have and don't have the this file. I'm confused.

    @yancek Thanks. I've taken a look, but I have zero idea how to utilize this and what to do next.

    You typically have to comment out or uninstall all ppas and hardware drivers.
    Then with new install, reinstall those ppas you may need or want.
    But new releases do not always have the same ppa available, either not required or not updated.

    Re: Can't upgrade Ubuntu 18.04 to 20.04

    The updater seems to want to have an official mirror in the sources list which you do not have.
    You could do the following:
    Add the following lines to the /etc/apt/sources.list:
    Code:
    deb http://archive.ubuntu.com/ubuntu/ bionic main universe multiverse
    deb http://archive.ubuntu.com/ubuntu/ bionic-security main universe multiverse
    You can use gedit to edit the file:
    Code:
    sudo gedit /etc/apt/sources.list
    Then update local caches:
    Code:
    sudo apt-get update
    Then try updating the system via a GUI utility from the first post.
