dnf error Fedora 28

El error en Fedora 28 al realizar un dnf update fue el siguiente:

Traceback (most recent call last):

El error me ocurrió al usar el comando siguiente:

# dnf update plexmediaserver-1.15.4.993-bb4a2cb6c.x86_64.rpm

Lo pude resolver quitando los repositorios de Plex que tenía instalados en yum.repos.d haciendo lo siguiente:

# cd /etc/yum.repos.d/
# rm plex.repo*

Sin embargo otros intentos pudieran servir en tu caso:

# dnf clean
# dnf update
# mv /var/lib/dnf/history /var/tmp/
# dnf clean all
# yum install python3-dnf.noarch --best --allowerasing
# yum reinstall python3-dnf
# dnf update python3
# dnf clean metadata
