I believe that one of the strong complains was related to not signed packages. The use case is that when I build RPMs locally and then I install them (see bellow).
dnf install *.rpm --setopt=localpkg_gpgcheck=true ... Package dnf-4.17.1-1.git.9598.552e61e.fc38.noarch.rpm is not signed Package dnf-automatic-4.17.1-1.git.9598.552e61e.fc38.noarch.rpm is not signed Package dnf-data-4.17.1-1.git.9598.552e61e.fc38.noarch.rpm is not signed Package python3-dnf-4.17.1-1.git.9598.552e61e.fc38.noarch.rpm is not signed Package yum-4.17.1-1.git.9598.552e61e.fc38.noarch.rpm is not signed Error: GPG check FAILED
