How to use Git credential store on WSL (Ubuntu on

Question

I've tried following these instructions: https://stackoverflow.com/a/40312117/21728 which basically do this:

sudo apt-get install libsecret-1-0 libsecret-1-dev
cd /usr/share/doc/git/contrib/credential/libsecret
sudo make
git config --global credential.helper /usr/share/doc/git/contrib/credential/libsecret/git-credential-libsecret

But when I do any network operation, I get this error:

** (process:7902): CRITICAL **: could not connect to Secret Service: Cannot autolaunch D-Bus without X11 $DISPLAY

That's logical I guess as there is indeed no X11 display.

How to make Git credentials caching work on Ubuntu on Windows (WSL)?

Answer 1

TL;DR

I've created a script that does this for you. I use it with my Chef orchestration.

Locate or install git-credential-manager.exe

1. Open cmd.exe and call where git-credential-manager.exe
   • If it returns a path, GREAT. Move on to converting the path.
   • If not...
2. In cmd.exe call where git.exe
   • If it does not return a path, the next step is to install the Credential Manager alone
   • If it does return a path, it will be something like:
   • C:\Program Files\Git\cmd\git.exe
   • Let's drop the everything after the next to last slash and change it like so:
   • C:\Program Files\Git\mingw64\libexec\git-core\git-credential-manager.exe
   • If that exists, GREAT. Move on to converting the path.
   • Otherwise...
3. Install Credential Manager from Microsoft's git repo, and then use where again to get the path.

Convert the path from DOS to Linux

We need to:

1. Replace the C:\ with /mnt/c/
2. Flip the slashes from \ to /
3. Escape spaces (and parenthesis if there are any) with double backslashes \\

So...

• "C:\Program Files\Git\mingw64\libexec\git-core\git-credential-manager.exe" becomes...
• "/mnt/c/Program\\ Files/Git/mingw64/libexec/git-core/git-credential-manager.exe"

My script above has a function for doing just that

dos_path_to_linux(){
    sed -e 's?\\?/?g' -e' s?[cC]:?/mnt/c?' <<<"$1"
}

But, as @12345ieee has since commented, a wslpath utility has been added to WSL build 17046. It's worth checking out, but I don't have access to Windows at this time to verify. (Note that even though a usage statement is given in the release notes in my link, it seems that the command doesn't currently include a usage statement, -h, etc.)

Configure git

1. In bash call git config --global credential.helper "<converted/path>"

Answer 2

Using Windows 10 and "WSL", I created a ~/.gitconfig file, but had mistyped the [credential] section label as [credentials]. I tried running git credential fill and then feeding its output to git credential approve, which might have worked, but I suspect not since it said "usage: git credential [fill|approve|reject]". Finally, I simply ran:

$ git config --global credential.helper cache

and then did a git pull; when prompted for user and password I typed them as usual. After that, it remembered it. I found it had added the (correctly named) section to my ~/.gitconfig:

[credential]
        helper = cache

I edited that to provide a much longer timeout:

[credential]
        helper = cache --timeout=144000

And it all seems to be working nicely now.

If you installed Git for Windows there is a windows integrated credential manager installed on your system.

You can run windows executables from WSL as found here.

To use it you can run the following command (assuming that your git for windows is installed on C:\Program Files\Git)

git config --global credential.helper "/mnt/c/Program\ Files/Git/mingw64/libexec/git-core/git-credential-manager.exe"
