    Hint: If there was a problem reaching remote content (see stderr output) and proxy is configured in the YUM/DNF configuration file, the proxy configuration is likely causing this error. Make sure the proxy is properly configured in /etc/dnf/dnf.conf. It's also possible the proxy settings in the DNF configuration file are incompatible with the target system. A compatible configuration can be placed in /etc/leapp/files/dnf.conf which, if present, it will be used during some parts of the upgrade instead of original /etc/dnf/dnf.conf. In such case the configuration will also be applied to the target system. Note that /etc/dnf/dnf.conf needs to be still configured correctly for your current system to pass the early phases of the upgrade process.
