Hi, I want to build a 5.10.83 kernel with RT patches downloaded from mirrors.kernel.org. But I am not able to find the public key for F394A423F8E67C26 which seems to be the public key used to create the signature of patches-5.10.83-rt58.tar.sign (I think the pub key used here is from Luis Claudio R. Gonçalves, but I cannot find it on ubuntu or openpgp keyservers) Question 1: Where can I get an “official” list of public keys used to create the signatures for the RT patches? Question 2: What is the preferred keyserver to retrieve the public keys? Thanks! Vincent
