Title: DNF execution failed with non zero exit code.
Summary: {"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.", "STDERR": "Warning: Package marked by Leapp to install not found in repositories metadata: rpcgen python3-pyxattr\nWarning: Package marked by Leapp to upgrade not found in repositories metadata: gpg-pubkey leapp-upgrade-el7toel8 leapp python2-leapp\nError opening /var/cache/dnf/rhel-8-for-x86_64-baseos-rpms-924d334b319c9ad8/packages/bzip2-1.0.6-26.el8.x86_64.rpm: No such file or directory\nPackage \"bzip2-1.0.6-26.el8.x86_64\" from repository \"rhel-8-for-x86_64-baseos-rpms\" has incorrect checksum\nError opening /var/cache/dnf/rhel-8-for-x86_64-baseos-rpms-924d334b319c9ad8/packages/sos-4.7.1-2.el8_10.noarch.rpm: No such file or directory
