You can remove cached packages by executing 'dnf clean packages'. Error: GPG check FAILED This is a development laptop and I never installed or need glusterfs-server. I could remove glusterfs-server, but other glusterfs packages seems to be required by libvirt, libguestfs and qemu. I tried "dnf clean all" and removed yum/dnf caches, but it does not help. In the meantime I could update by excluding glusterfs. I hope someone has a better solution. Nir
