Install newest version of git

+1. The update process for the internal version of git failed to install, but I was able to switch to the system git, update from 1.8 to 2.7, and the ssh-agent issue was resolved.

same issue i am getting git version is 2.6.3 and source tree version is 2.3.5 so please help me how to resole it.


Awaiting for response!

Atlassian! seriously?!

Best solution... uninstall this s...

I updated git bash and integrate to the source tree via Tool > Option > Git > Use System Git

It worked 

I fallow same steps, but having same error message window comes.

Step I did : 

1>  Update embedded Git (Tool > Option > Git > "Update Embedded Git" - button)

This will download PortableGit.7z at "<user-folder>\AppData\Local\Atlassian\SourceTree"

2> Extract PortableGit.7z

3> Use as system git (Tool > Option > Git > Use System Git)

select "\bin\git.exe" from extracted folder

I fallow same step except in step 3 i select Use Embedded Git option and issue has gone. thanks


Excellent, I got same issue and like said Kamle I just select "Use Embedded Git" option  too and work, thanks!

ankti pate answer did the job, but Sourcetree auto upgrade failed, it could not dezipp the PortableGit.7z.

This is how I managed to fix it :

  1. Launch update Embedded Git (tools/options/git)
  2. If it failed : close sourcetree
  3. Go to "<user-folder>\AppData\Local\Atlassian\SourceTree"
  4. Rename  git_local to git_local_old
  5. Unzipp PortableGit.7z manually (with 7zip)to git_local
  6. restart sourcetree
  7. Go to (tools/options/git and check that Use Embedded Git is hcecked and the version is 2.6.1

@Craig Chapman is right. Installing newest version is solution in this problem. It also helped me.

I installed git version 1.9.5 but still facing  same issue.
