gpg: key B4D2D216F1FD7806: new key but contains no user ID - skipped
(I’m trying to import the key to export it in .gpg format and put it somewhere in /etc/apt/trusted.gpg.d)
So, it does not work for me. I’m using Debian 10.
After some search, I found this:
You are probably using the keys.openpgp.org keyserver, which has an owner approval system – it will strip all user IDs unless the owner of the corresponding email address has allowed them to be published.
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://download.jitsi.org stable/ InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY B4D2D216F1FD7806
So, the usual way to handle key changes is to have a keyring package and add the new key there some time before switching the archive to this new key. This way, any user that update regularly will have the new key already installed and everything just work.
And there is already a jitsi-archive-keyring package. Unfortunately it only contains the old key, not the new key. Can you please add the new key here as well? And maybe make a note to do this first next time .
