    23 -> 28 system upgrade [Errno 111] Connection refused

    Hey guys!
    Is there any real threat fix this error?


    dnf system-upgrade download --releasever=28 --allowerasing --nogpgcheck -y
    or
    dnf system-upgrade download --refresh --releasever=28 --nogpgcheck

    ...
    xmlrpc-c-client.x86_64 1.51.0-5.fc28
    xz.x86_64 5.2.4-2.fc28
    xz-libs.x86_64 5.2.4-2.fc28
    zip.x86_64 3.0-21.fc28
    zlib.x86_64 1.2.11-8.fc28
    Complete!
    Download complete! Use 'dnf system-upgrade reboot' to start the upgrade.
    The downloaded packages were saved in cache until the next successful transaction.
    You can remove cached packages by executing 'dnf clean packages'.

    That might be because some port is closed on the firewall, thus it can't create a connection. Maybe is trying to send an email.

    I am not too familiar with your setup, it seems like it is some kind of a container?

    In that case system-upgrade plugin might not work since it doesn't have a real system below it. Try with regular dnf instead.

    Code:
    dnf --releasever 28 upgrade
    Backup the data before you try that in case something goes wrong.

    That upgrade (5 levels) is not supported according to what I have seen. They recommend only doing a single level upgrade, although I have successfully done a 26 to 28 upgrade (2 levels) myself. I personally would not try doing a 23 to 28 upgrade.

    Maybe you could do a clean install from an FC28 iso.
    Make sure you know what repos and packages you have installed, and as always, it is a good idea to do a backup before that upgrade/install.

    Also, why are you using nogpgcheck? The download plugin automatically updates the keys for you as long as you are using the official sites (and that might be the cause of the error).

    I personally like to use "dnf update -y" followed by "dnf system-upgrade download --best --refresh --allowerasing --releasever=28 -y" and it has worked well for upgrades each time as I stepped from FC25 to FC28 (no more than 2 versions at a time).
