Armadilloフォーラム

お世話になっております。

Armadillo-IoT G3のSDイメージをATDE8上で作成しようとしております。
ATDE上でat-debian-builder-v2.1.3内のbuild.shを実行し、ファイルシステムアーカイブ(debian-buster-....tar.gz)は作成されますが、
以前作成したファイルの1/3程度のサイズとなります(8/15頃作成)。
ログを確認するとGPG errorが発生が発生しているようですが、これが原因でしょうか？
その場合、回避策をご教示いただけませんでしょうか？コマンド実行時のログを以下に添付いたします。

お手数をお掛けしますが、よろしくお願いいたします。
