check  git status  and  git pull  in the shell and find out what s wrong   and my problem is http proxy node in config  therefore Github Windows should much more smart like just pop the shell and give more tips after the error s  emit

I had the same problem when I tried from inside Visual Studio and  git status  in shell showed no problem  But I managed to push the local changes with  git push  via shell

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

This error comes because of a merge conflict in files  I faced it after I had updated my Maven Project s pom xml but didn t commit it  Using   git status error  Your local changes to the following files would be overwritten by merge   lt my project gt  pom xml Please  commit your changes or stash them before you can merge  Aborting   as the above post suggested helped finding any conflicting changes and you can decide to discard or commit

I had the same issue  and  git status  also showed no problem  then i just Restarted the holy GitHub client for windows and it worked like charm

This is probably an edge case  but every time I ve got this specific error it is because I ve recently mapped a drive in Windows  and powershell cannot find it   A computer restart  of all things  fixes the error for me  as powershell can now pick up the newly mapped drive  Just make sure you connect to the mapped drive BEFORE opening the github client

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

The debug log may provide some insight   I m using v3 3 4 0  your experience may differ but should be similar   From the settings menu choose  About Github Desktop       Click the link to view the debug log   In my case there was a very clear error       fatal error - cygheap base mismatch detected - 0x1157408 0x1167408  This problem is probably due to using incompatible versions of the cygwin DLL   It even provided some helpful tips to solve the problem   I m not sure why this information isn t exposed in the error prompt  but at least it was available

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

I had the same issue  I removed the repo from the GitHub Windows client  right-click menu  and re-added it  When I re-added  I noticed I had about 300 uncommitted changes and it was reporting a memory error  I discarded all the changes and then sync started working fine again   Rookie Git user - I m sure there are better ways to do this on the command line

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

User · Answer

This error also occurs if the branch you re trying to sync has been deleted    git status won t tell you that  but you ll get a  no such ref was fetched  message if you try git pull

I had the same problem  In my case git could not find the global variable  HTTP PROXY   simply because Windows was not providing using it   I solved it by excluding the variable from the git config file  located in  USERPROFILE   gitconfig     http      proxy    HTTP PROXY

User · Answer

I had this problem and found it was to do with the proxy  I fixed the problem using this command     git config --global http proxy  HTTP PROXY

User · Answer

Have you changed your Windows password recently  or at least the one you use to connect to your proxy   This was my problem  and git status couldn t help me  I had to change my login credentials in the   git config  file to get past this error

User · Answer

When it says that  just open the shell and do git status  That will give you a decent idea of what could be wrong and the state of your repo   I can t give you a specific error for this as it happens for many reasons in Github for Windows  like say some problem in updating submodules etc

User · Answer

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
