Abstract
Accessing GitHub with Visual Studio sometime causes error. ITs typical case is the image attached above. It says that the certificate is not found at the designate path.
This is the cause of error, but it is not root cause. The another factor makes Git in Visual Studio pointing to wrong destination, and this is the root cause.
This post introduces
| Specify a cause | command "git config" |
| fix a problem | edit file "gitconfig" |
| typical solution and its problem | copy certificate |
Specify a cause with the command "git config"
Certificate (CRT file) and its path is described at [http] section in a file "gitconfig". Visual Studio has its own Git and it is saved at the next path.
C:\Program Files\Microsoft Visual Studio\2022\Community\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\Git\mingw32\bin
Execute the next command here.
git conofig -l --show-origin

This output indicates that multiple "gitconfig" below are referred.
- gitconfig - 1, this is for system configuration of Visual Studio Git
C:/Program Files/Microsoft Visual Studio/2022/Community/Common7/IDE/CommonExtensions/Microsoft/TeamFoundation/Team Explorer/Git/etc/gitconfig
- gitconfig - 2, this is for user configuration of Visual Studio Git
C:/Users/%USERNAME%/.gitconfig
- gitconfig - 3, this is for system configuration of original Git. Probably for GitHub Desktop in mycase.
C:/Program Files (x86)/Git/etc/gitconfig
Reading [http] section of these files, found that configuration between gitconfig-1 and 3 is different as
| gitconfig - 1 | sslCAinfo = %(prefix)/ssl/certs/ca-bundle.crt |
| gitconfig - 3 | sslCAinfo = /bin/curl-ca-bundle.crt |
And comparing these paths and the error message at the top of this post, would notice that Visual Studio refers inappropriate path below, in spite of it should refer appropriate one.
- Inappropriate path
C:\Program Files\Microsoft Visual Studio\2022\Community\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\Git\mingw32\bin\curl-ca-bundle.crt
- Appropriate path
C:\Program Files\Microsoft Visual Studio\2022\Community\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\Git\mingw32\ssl\certs\ca-bundle.crt
fix a problem
Using multiple "gitconfig", one configuration is inherited and given priority. This inheritance composes inappropriate not intended. As this inheritance is not avoided, solution is to make it not produced.
Its direct way is to make inappropriate configuration commented. In the case of this post, configuration from gitconfig - 3 is inherited. Its [http] section should be commented as
[http] ;sslCAinfo = /bin/curl-ca-bundle.crt
Typical solution and its problem
Typical solution other than editing "gitconfig" is to copy certificate (CRT file) from appropriate path to inappropriate one. But this is not recommended here.
Example, when the other Visual Studio (example its newer version) is installed, it would bring the other own Git with newly generated certificate together. Appropriate path and inappropriate one may be composed again at that time. And new certificate must be copied from one to the other again.
Putting assumption that the path should be kept appropriate, user should care of appropriate path, not certificate.
