我正在使用 Tizen SDK (2.4.0_Rev5) 在我的 Gear S2 上启动演示应用程序 HelloTizen (wearable-2.3) 但它失败了，并出现以下错误：
Unknown Error [81]
Unknown Error [81]
当我尝试安装它时，sdb install HelloTizen.wgt我得到以下输出：

有以下输出sdb dlog：

因此，这似乎是与证书相关的错误。我确实Security Profiles使用一个生成作者证书和经销商自动证书生成了我的证书。我也用过Register Certificate，但我不知道它是否有效，因为当我点击确定时，什么也没发生。
我做的另一件事是启用Permit to install applications我的设备。但是，至于证书注册，我不知道它是否有效，因为什么也没发生。我签到了/home/developer，没有device-profile.xml文件。
