GPG Keys

AlmaLinux OS Foundation signs all of its software packages using a GPG signature key, which is verified by default when installing packages via dnf or graphical update tools. If a package is not signed or has an invalid signature, dnf or graphical update tools will warn the user and will refuse to install it.
Es wird empfohlen, die Signatur eines Pakets vor dem Installieren zu verifizieren.
