注意：
在构建服务器上，我已经安装了 .Net 4.6.2，因为我几乎没有其他针对 4.6.2 和 4.5.2 的项目。
另请注意，我没有在构建服务器上安装VS 2015，但是我确实在构建服务器上安装了VS 2013。
我不确定在安装 .Net 核心 SDK 之前是否还需要安装 VS 2015
更新1
基于 google 搜索 0x80072f76 错误与互联网连接有关，但是连接在服务器上正常工作，这就是我首先下载安装程序的方式。
更新 2
所以我通过允许 IE 下载文件来修复 0x80072f76 问题。但是现在我得到了以下日志的不同错误 0x80070490 element not found。 （注意我只包含了错误行的日志）

这当然不是安装程序本身的问题，而是您的 IE 配置选项的问题。
这是来自 Microsoft Community:
的解决方案
I would suggest you to enable the file download in Internet Explorer.
a. Open Internet Explorer.
b. Click Tools and then options.
c. Click on the security tab.
d. Select the Internet Zone.
e. Click on the Custom Level Button and then scroll down to Download.
f. Make sure to enable File download.
g. Click Apply and Ok
h. Restart Internet Explorer and check if that helps.
按照以上步骤应该可以解决问题。您可以通过打开 IE 并尝试下载任何文件并确认它能够这样做来进行验证。
对于 0x80070490 element not found 问题，我在这里找到了答案 https://github.com/dotnet/core/issues/271
解决方案 1：手动安装 VC_redist.x64.exe
- 从 this link 下载并安装适用于 Visual Studio 2015 的 Visual C++ Redistributable。
- 重新安装 .NET Core SDK
解决方法二：暂时关闭IE ESC：
这个解决方案也适用于我。 Here如何禁用 IE 增强安全配置：
- 打开服务器管理器。
- 点击左侧的"Local Server"。
- 在服务器管理器的右侧，如果您看到 IE 增强的安全配置是 "On"，请单击 "On"。
- 当弹出新的 windows 时，为管理员和用户关闭 IE ESC。
- 重新安装 .NET Core SDK。
- 安装后打开IE ESC。
即使我在安装 32 位 .netcore SDK 时也遇到了同样的 错误
我刚刚 安装了 Visual C++ Redistributable Packages 来自
https://www.microsoft.com/en-in/download/confirmation.aspx?id=48145 并重新启动了我的机器。
问题就解决了！！
我使用 Jenkins 为 CI 设置构建服务器。我正在尝试从 https://www.microsoft.com/net/download 安装 .NET Core SDK
但是我尝试执行下载的 DotNetCore.1.0.1-SDK.1.0.0.Preview2-003131-x64.exe 我得到未指定的错误

注意：
在构建服务器上，我已经安装了 .Net 4.6.2，因为我几乎没有其他针对 4.6.2 和 4.5.2 的项目。
另请注意，我没有在构建服务器上安装VS 2015，但是我确实在构建服务器上安装了VS 2013。
我不确定在安装 .Net 核心 SDK 之前是否还需要安装 VS 2015
更新1
基于 google 搜索 0x80072f76 错误与互联网连接有关，但是连接在服务器上正常工作，这就是我首先下载安装程序的方式。
更新 2
所以我通过允许 IE 下载文件来修复 0x80072f76 问题。但是现在我得到了以下日志的不同错误 0x80070490 element not found。 （注意我只包含了错误行的日志）

这当然不是安装程序本身的问题，而是您的 IE 配置选项的问题。
这是来自 Microsoft Community:
的解决方案I would suggest you to enable the file download in Internet Explorer.
a. Open Internet Explorer.
b. Click Tools and then options.
c. Click on the security tab.
d. Select the Internet Zone.
e. Click on the Custom Level Button and then scroll down to Download.
f. Make sure to enable File download.
g. Click Apply and Ok
h. Restart Internet Explorer and check if that helps.
按照以上步骤应该可以解决问题。您可以通过打开 IE 并尝试下载任何文件并确认它能够这样做来进行验证。
对于 0x80070490 element not found 问题，我在这里找到了答案 https://github.com/dotnet/core/issues/271
解决方案 1：手动安装 VC_redist.x64.exe
- 从 this link 下载并安装适用于 Visual Studio 2015 的 Visual C++ Redistributable。
- 重新安装 .NET Core SDK
解决方法二：暂时关闭IE ESC：
这个解决方案也适用于我。 Here如何禁用 IE 增强安全配置：
- 打开服务器管理器。
- 点击左侧的"Local Server"。
- 在服务器管理器的右侧，如果您看到 IE 增强的安全配置是 "On"，请单击 "On"。
- 当弹出新的 windows 时，为管理员和用户关闭 IE ESC。
- 重新安装 .NET Core SDK。
- 安装后打开IE ESC。
即使我在安装 32 位 .netcore SDK 时也遇到了同样的 错误 我刚刚 安装了 Visual C++ Redistributable Packages 来自 https://www.microsoft.com/en-in/download/confirmation.aspx?id=48145 并重新启动了我的机器。
问题就解决了！！
