Official documentation

Method 2 Import via GnuPG then rpm

Compatible with RHEL, CentOS, AlmaLinux and Rocky Linux (both yum and dnf).

RHEL / CentOS / AlmaLinux — bash
$ gpg --keyserver hkps://keys.openpgp.org --recv-keys F42ED6FBAB17C654
$ gpg --export --armor F42ED6FBAB17C654 | sudo rpm --import -
$ sudo yum check-update || sudo dnf check-update

After importing the key

Run sudo apt-get update (or your distro's equivalent) again. If successful you should see Hit: lines with no EXPKEYSIG warnings. Still broken? Check that your /etc/apt/sources.list.d/ entry references the correct [signed-by=…] keyring path.
