Hey Dan, So I had tried using the documented method, but it had resulted in an error 'No Signed-By field' on apt update. Seemingly, the Key field doesn't automatically create the Signed-By field. This is actually what led to my approach in the previous message. I came across https://bugs.launchpad.net/ubuntu/+source/subiquity/+bug/2070320, where Chris Peterson outlined a methodology (in his message on Nov. 13th) that adds the keys in the sources section and references them in the template with the fingerprint.
I was unsure about which approach should be followed - adding keys in the sources and referencing in the template, or adding a Signed-By field to the documented approach. I'm gathering that the latter is preferred: sources_list: | Types: deb URIs: $PRIMARY Suites: noble noble-updates noble-backports Components: main Signed-By: <fingerprint or raw key> Key: | -----BEGIN PGP PUBLIC KEY BLOCK----- ... key ... -----END PGP PUBLIC KEY BLOCK----- I'll follow up with the customer with this and see if we can get this working in their environment.
