Container core-fedora-latest terminated by signal KILL

When installing a package in the coreos toolbox, you are suddenly escaped from the container.

warning: /var/cache/dnf/fedora-310f9d37d74ceec1/packages/glances-2.5.1-2.fc24.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID fdb19c98: NOKEY
Container core-fedora-latest terminated by signal KILL.

The Fix: Go back to older version of Fedora
