Is this ok [y/d/N]:
Ou talvez baixar esses pacotes genéricos ... e depois rpm -e --no-deps fedora-logos fedora-release fedora-release-notes
você mencionou instalá-los via rpm novamente - algo como: rpm -ivh generic-*
. Depois disso, você provavelmente quer verificar se tudo está bem com package-cleanup --problems
(utilitário do pacote yum-utils ).
