问题
In Visual Studio 2019, we have been using the GitHub extension successfully since before release. Now, all of the sudden, when we push, pull, or sync, we receive the following in the Output window:
Warning: 'C:\ProgramData/Git/config' has a dubious owner: '(unknown)'.
For security reasons, it is therefore ignored.
To fix this, please transfer ownership to an admininstrator.
回答1:
You should check if 'C:\ProgramData/Git/config' actually exists. If it doesn't you can just create it and paste the following into the file:
[core]
symlinks = false
autocrlf = true
fscache = true
[color]
diff = auto
status = auto
branch = auto
interactive = true
[help]
format = html
[rebase]
autosquash = true
This worked for me.

I fixed it by going to Visual Studio Installer, choosing individual component and searching for "Git". In my case the "Git for Windows" and "GitHub Extension for Visual Studio" was now unchecked/not installed for some reason..
These are the extensions I needed: Visual Studio Installer Git
Installing those create the ProgramData\Git\config file and the error was gone.

Delete or rename the existing file at that location is also an option. It looks like it's parts of some lower level windows (or MSYS2/Cygwin) security that's brought in via libgit.lib.
Why the created file has the wrong owner is not yet known.
Who/what is the owner for that existing file? What language is in use?
It's been noted as an issue at https://github.com/git-for-windows/git/issues/2304 but isn't resolved yet.

We ran into this exact issue after upgrading Git to version 2.23.0.windows.1 on our build agents.
The fix that worked for us was to change the owner of C:\ProgramData/Git/config to Administrators. Note that this is different to the Administrator user!
To do this, right-click on C:\ProgramData/Git/config and select Properties then the Security tab.
And click Advanced...
Use the Change link to set the owner to Administrators.

Uninstall Git and install a downgraded version. The version that shows this problem is the 2.23.0. Downgrade it to the 2.22.0 and it works fine without this problem.
Git releases: All git releases Git 2.22.0: Version without this issue

Delete the file config file from C:\ProgramData/Git directory and try again.

I had this problem with Git 2.24.0.2 and visual studio 2019 - 16.2.3. I couldnt create the path and config file in c:/ProgramData/git/, as I dont have admin rights. It turned out that the windows credentials stored are expired for my user account and when updated using control panel > user accounts > credential manager > Generic credentials for git helped to resolve the issue in my case
回答8:
The "Git" folder was missing from the path c:/ProgramData/Git/Config. I created the folder (not the config file) and it worked fine
