Lỗi nằm trong lệnh build Kaniko cho image demo-rockylinux, khi cấu hình pkgconf-2.2.0. Trước tiên, hãy kiểm tra định nghĩa build của image và các dependency của toolchain, sau đó tái hiện bước configure. Được xem là hoàn tất khi image build vượt qua configure mà không gặp lỗi “no acceptable C compiler found”.
