Github Windows 'Failed to sync this branch'

Question

I am using Github Windows 1.0.38.1 and when I click the \'Sync\' button after committing, I get the error

Answer 1

Along the lines of the HTTP Proxy answers, this can also happen due to a VPN connection. Disconnecting my VPN connection solved it for me.

Answer 2

I tried with Android Studio to commit Changes and push it to master But Window Showed a popup that I have to enter Github Credentials (https://github.com). I did Signup with my Gmail account So I tried to enter my Gmail id along with its password, Obviously Git do not have my Gmail password and can't match it with what I'm providing, So I ended up canceling the push.
When I tried to sync my changes through GitHub GUI Window I encounter this error. On git status command Git Shell suggested to push changes as

Your branch is ahead of 'origin/master' by 1 commit.
  (use "git push" to publish your local commits)

I did the same as Git Shell suggested (git push) and everything is ok now.

Note: for someone who is new to git you have to change your path to the folder where your .git file is otherwise on Every Command you enter Git Shell will show error that its not a git repository.

fatal: Not a git repository (or any of the parent directories):

For example if your Project is in D drive in some folder you have to do something like below as you do in cmd to change directory.

cd D:\someFolder     // if your project is not deep in `D`

And if its within nested folder in D

cd D:\somefolder\someNestedFolder\nestedInNested     // if your project is not deep in `D`

If someone know how to login into Github popup from windows as I did signup with google account and here are 2 fields only Github username, password Please let me know. I have resolved the issue but with waste of some time so I want to know about login too.

Answer 3

I had the same problem. It happened to me because of some conflicting changes. I removed the local repository of my project from my desktop and then cloned it again from the github website (using clone option in my account), the error was gone.

Answer 4

One more thing that can cause this is when you map a network drive or connect a VHD after GitHub Desktop has already been started. The reason for this is that GitHub Desktop uses ssh-agent from the portable GIT install to establish connections, and never closes it... even if you uninstall the application. The process starts with no knowledge of the new drive and never refreshes itself, and when it is used to run the GIT commands to work on your repo it fails because it doesn't understand the paths.

The solution in this instance is to close GitHub Desktop and use Task Manager to terminate the running ssh-agent before starting it again. This will start a new instance of ssh-agent when needed which will pick up the new drive mappings, etc.

Make sure that the branch you are trying to push to isn't protected. I was trying to push to a protected branch and failed same as you.
