I was getting "Error in com.github.amsysuk-recipes.pkg.opera: Processor: CodeSignatureVerifier: Error: Code signature verification failed. Note that all verifications can be disabled by setting the variable DISABLE_CODE_SIGNATURE_VERIFICATION to a non-empty value." errors, updating the certificate leaf appears to resolve this.
