使用VS 2015 Update 3克隆远程存储库时遇到错误（TFS 2015 Update 3） [英] Error encountered while cloning the remote repository with VS 2015 Update 3 (TFS 2015 Update 3)

问题描述

我最近升级到客户端的VS 2015（更新3）和服务器端的TFS 2015（更新3）。 Git操作工作了一段时间，然后在尝试克隆git repo时开始出现以下错误：

 克隆时遇到的错误远程存储库：发送请求时发生错误。 
 
内部异常：
远程服务器返回错误：（401）未经授权。 
 
内部例外：
安全包中没有可用凭证
  

<但是我可以在浏览器中导航到回放而没有任何问题。然后，我想这可能是由于我的客户端设置。我尝试删除VS缓存以及TFS缓存。没有工作。当我使用Fiddler时，应该提供以下信息：

它显示以下信息：

 请求1：
 GET https：// myhost / tfs / transact / Transact / _git / MY-REPO / info / refs？service = git-upload-pack HTTP / 1.1 
 User-代理：git / 1.0（libgit2）Team Foundation（devenv.exe，14.102.25521.0，Enterprise，SKU：37）

有了这些信息，我在我的visual studio文件夹中搜索了libgit2 *。*文件。我发现了LibGit2Sharp.dll的几个实例。它们都具有相同的版本（0.22.0.0），但一个实例的版本是14.0.25029.0。我试图在14.0.25029.0之上复制0.22.0.0版本。但视觉工作室在发布期间对此抱怨。在C：\程序文件（x86）\微软Visual Studio 14.0 \ Common7 \ IDE \ Extensions文件夹中找到带有14. *版本的文件夹，它包含几个以Microsoft.TeamFoundation开头的dll。 。所有这些dll的版本为：14.102.25521.0（这是我在小提琴跟踪中发现的）。

看起来我处于正确的问题区域，但不确定如何解决错误。

有什么想法？

解决方案

一个星期，我今天发布了这个问题。但在发布之后，我登陆了一个解决方案。

它与visual studio / tfs升级无关。我必须输入错误的tfs证书信息（同时检查记住我框）。记住我的功能，团队资源管理器从来没有给我一个机会来纠正凭据信息，并可能保留使用存储错误的凭据。以下是我必须解决的问题：

1. 控制面板\用户帐户\Credential管理器


2. 删除所有与tfs相关的凭证。


3. 启动visual studio


4. 它现在会提示您输入tfs证书信息。

问题解决了。

I have recently upgraded to VS 2015 (Update 3) on the client side and TFS 2015 (Update 3) on server side. The Git operations worked for a while, then I started getting following error when trying to clone a git repo:

Error encountered while cloning the remote repository: An error occurred while sending the request.

Inner Exception:
    The remote server returned an error: (401) Unauthorized.

    Inner Exception:
        No credentials are available in the security package

But I can navigate to repo in the browser without any problems. Then, I figured this may due my client side settings. I tried removing the VS cache as well as TFS cache. Nothing worked. When I used Fiddler, it should following information:

It revealed following information:

Request 1:
GET https://myhost/tfs/transact/Transact/_git/MY-REPO/info/refs?service=git-upload-pack HTTP/1.1
User-Agent: git/1.0 (libgit2) Team Foundation (devenv.exe, 14.102.25521.0, Enterprise, SKU:37)
Host: myhost
Accept-Encoding: gzip
Connection: Keep-Alive

Response 1:

Request 2:
GET https://myhost/tfs/transact/Transact/_git/MY-REPO/info/refs?service=git-upload-pack HTTP/1.1
User-Agent: git/1.0 (libgit2) Team Foundation (devenv.exe, 14.102.25521.0, Enterprise, SKU:37)
Accept-Encoding: gzip
Authorization: NTLM TlRMTVNTUAABAAAAB4IIogAAAAAAAAAAAAAAAAAAAAAKAEM6AAAADw==
Host: myhost

Response 2:
HTTP/1.1 401 Unauthorized

With this information, I searched for libgit2*.* file in my visual studio folders. I found several instances of LibGit2Sharp.dll. All of them have same version (0.22.0.0) but one instance had the version 14.0.25029.0. I tried copy the version 0.22.0.0 over on top of 14.0.25029.0. But visual studio complained about it during launch. The folder with 14.* version is found in "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions" folder and it contains several dlls that start with "Microsoft.TeamFoundation.". All of those dlls have the version: 14.102.25521.0 (which is what I found in the fiddler trace).

Looks like I am at the right problem area but not sure how to fix the error.

Any ideas?

解决方案

After struggling with the above problem for a week, I posted the question today. But right after posting, I landed on a solution.

It has nothing to do with visual studio/tfs upgrade. I must have entered wrong tfs credential information (while checking remember me box). With remember me feature, the team explorer never gave me a chance to correct the credential information and probably kept using stored wrong credentials. Here is what I had to do to correct the issue:

1. Control Panel\User Accounts\Credential Manager
2. Remove any tfs related credentials.
3. Launch visual studio
4. It will now prompt you for tfs credential information.

Problem solved.
