-Fixing “cannot find signatures with metadata for snap” Error in Ubuntu and other Linux
-======
-
-The other day I was trying to install [massCode][1] application. For installation, it provided a Snap file to download.
-
-When I tried to install the application from Snap file
-
-```
-sudo snap install snap_file
-```
-
-It gave me the following error:
-
-**error: cannot find signatures with metadata for snap “masscode_2.6.1_amd64.snap”**
-
-![cannot find signature with metadata for snap][2]
-
-That was strange. While [adding external repositories in Ubuntu][3], you have to add the GPG key. But no such things were provided by the developer here.
-
-The ‘fix’ is easy and simple. Let me explain it to you.
-
-### Handling “cannot find signatures with metadata for snap” error
-
-There are no signatures involved here.
-
-What happens is that you have downloaded a Snap installer file from a third party. The snap mechanism in Ubuntu expects you to get the snap packages from the official snap store.
-
-Since it doesn’t come from the snap store, you see the ‘cannot find signatures with metadata for snap’ error message. The error message is not descriptive, like most error messages.
-
-So, what’s the solution here?
-
-Any snap package that is not distributed through the Snap store has to be installed with the**–dangerous flag**. That’s the rule.
-
-```
-sudo snap install --dangerous path_to_snap_file
-```
-
-This way, you tell the snap package manager to explicitly install the snap package.
-
-Here, I used this flag and was able to install massCode from its snap package successfully.
-
-![installing third party snap packages][4]
-
-How ‘dangerous’ is it to install snap packages this way? Almost the same as downloading and [installing packages in deb format][5].
-
-In my opinion, if you are downloading the snap package from the project developer’s website, you are already entrusting the project. In such cases, you can install it with the –dangerous flag.
-
-Of course, you should first search if the package is available in the snap store or not:
-
-```
-snap find package_name
-```
-
-I hope this quick little tip helped you fix the Snap error. If you have questions or suggestions please let me know. If you want to learn more, see [this guide on using Snap commands][6].

+
+修复 Ubuntu 和其他 Linux 中的 “cannot find signatures with metadata for snap” 错误
+======
+
+前几天我试图安装 [massCode][1] 应用。对于安装，它提供了一个 Snap 文件以供下载。
+
+当我尝试从 Snap 文件安装应用程序时
+
+```
+sudo snap install snap_file
+```
+
+它给了我以下错误：
+
+**error: cannot find signatures with metadata for snap “masscode_2.6.1_amd64.snap”**
+
+![cannot find signature with metadata for snap][2]
+
+这很奇怪。[在 Ubuntu 中添加外部仓库][3]时，你必须添加 GPG 密钥。但是这里的开发人员没有提供这样的东西。
+
+“修复”简单易行。让我给你解释一下。
+
+### 处理 “cannot find signatures with metadata for snap” 错误
+
+这里不涉及签名。
+
+发生的情况是你从第三方下载了 Snap 安装程序。 Ubuntu 中的 snap 机制希望你从官方 snap 商店获取 snap 包。
+
+由于它不是来自 snap 商店，因此你会看到 “cannot find signatures with metadata for snap” 的错误消息。与大多数错误消息一样，错误消息不是描述性的。
+
+那么，这里的解决方案是什么？
+
+任何未通过 Snap 商店分发的 snap 包都必须使用 **-dangerous** 选项进行安装。这就是规则。
+
+```
+sudo snap install --dangerous path_to_snap_file
+```
+
+这样，你告诉 snap 包管理器显式安装 snap 包。
+
+在这里，我使用了这个选项并且能够成功地从它的 snap 包中安装 massCode。
+
+![installing third party snap packages][4]
+
+以这种方式安装 snap 包有多“危险”？几乎和下载并[安装 deb 格式安装包][5]相同。
+
+在我看来，如果你是从项目开发者的网站上下载 snap 包，你已经在信任项目了。在这种情况下，你可以使用 –dangerous 选项安装它。
+
+当然，你应该首先搜索该软件包是否在 snap 商店中可用：
+
+```
+snap find package_name
+```
+
+我希望这个快速的小技巧可以帮助你修复 Snap 错误。如果你有任何问题或建议，请告诉我。如果你想了解更多信息，请参阅[这个使用 Snap 命令指南][6]。
