The current release build brave-browser-1.10.93-1.x86_64.rpm is signed key id 82d3dc6c, which does not match either of the public key fingerprints on https://brave.com/signing-keys/ or on the linux installation page. Those fingerprints are c2d4e821 (brave-core) and 6a8a26f9 (brave-core-nightly) respectively.
Searching through community posts I see this isn’t the first time the signing key has changed. Do you guys not have some consistent process for publishing the new public keys when they change? Because I can’t find it.
Update: I see that there is a brave-keyring rpm in the same repository. It doesn’t contain the public key the package was signed with itself either!
