Comment 1 for bug 1727874

Moreover apt-key should not be used at all since it has been deprecated with newest APT and will be removed in Q2/2022. I agree with Alistair that the key should be shipped within the effective directory /etc/apt/trusted.gpg.d/raspbian-archive-keyring.gpg directly, like the raspberrypi.org and Debian keyring packages do.
