I wanted to update my repos on Raspbian server on which I have installed OMV and Jellyfin but I still get this error:
Err:6 http://httpredir.debian.org/debian bullseye-backports InRelease
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 0E98404D386FA1D9 NO_PUBKEY 6ED0E7B82643E131

I tried to update my keys using
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys [KEY]
but it always wrote back
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).

Anyone knows what could be wrong? Thanks
