Hello, The signing key expired a few days ago: gpg --homedir /etc/portage/gpg --list-keys /etc/portage/gpg/pubring.gpg ---------------------------- pub 4096R/96D8BF6D 2011-11-25 [expired: 2015-11-24] uid [ expired] Gentoo Portage Snapshot Signing Key (Automated Signing Key) On another note I find it strange that emerge still accepts the key and syncs portage. It only prints that the key expired. Regards, Sebastian Reproducible: Always
The key has been renewed and re-published before the expiry. Update your keyring.
