I am using a setup on Windows 10 x64 where I install and manage git via scoop, rather downloading and executing the installer myself. Via the PowerShell, I ran
scoop install git
scoop install openssh
[environment]::setenvironmentvariable('GIT_SSH', (resolve-path (scoop which ssh)), 'USER')
However, now when I try to run commands in the Git Bash like
git clone git#example.org:vendor/repository.git
or a simple
git push/pull
I only get
CreateProcessW failed error:193
ssh_askpass: posix_spawn: Unknown error
instead of the Git Bash asking me for my SSH key's passphrase.
I am using the same setup (git installed via scoop) on many other Windows 10 x64 and no problems occur there. So I am not sure what is going wrong on this one. I previously had git installed without scoop on the same machine and the Git Bash was working fine. I uninstalled git completely (and also restarted the machine, just to be sure) before re-installing it via scoop instead.
The SSH_ASKPASS environment variable contains the following, in case this is relevant:
$ echo ${SSH_ASKPASS}
/mingw64/libexec/git-core/git-gui--askpass
Not sure what that folder refers to (something internal to the Git Bash presumably?), since it obviously does not exist like that on my machine.
Update
When using git-with-openssh instead of just git and openssh separately it works. However, I don't use that on my other machines, so I'd still like to know why it's not working here.
I'm pretty sure my answer does not address the OP's original case. But as of 2020, there seems to be a similar issue with a different way of solving it, and that's how I did in my case.
Part of the problem is, now Windows 10 has its own version of OpenSSH available, and at least in the case of my work's machine it seems that option is enabled by default.
This bundled OpenSSH is not compatible with Git bash though, so if you wants to use it, you must force git use scoop's provided OpenSSH (either from openssh or git-with-openssh packages). That means overwriting GIT_SSH environment variable, e.g. by adding a line similar to this to your .bashrc:
export GIT_SSH='C:\Users\rogs\scoop\apps\git-with-openssh\current\usr\bin\ssh.exe'
Hope it helps.
Even if this topic is already very old, the problem persists. I found out that its enough to simply unset the environment variable to get rid of this error.
unset SSH_ASKPASS
Just put this in your .bash_profile and/or your .bashrc.
Indeed I have same issue which is mentioned here "Why does bash (from git installation) give me segmentation fault suddenly?
"
My git was working properly. But I need to regenerate keygen value and I got segmentation fault. I remoted git and installed the latest version of git (2.19.0-64-bit). I tried with git-bash from search, bash.exe from bin folder , git.exe from bin folder , git-bash.exe under Git Folder and git-cmd.exe under Git folder. The results are same.
After I read the link I shared above , I checked the windows updates as well. But there is no update.
Is there any idea ? Thanks in advance
2.9 is not the latest, one: 2.19 is.
Try (for testing) and uncompress the latest Git for Windows portable archive PortableGit-2.19.0-64-bit.7z.exe anywhere you want.
Then setup a simplified path in a CMD session.
set PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem
set GIT_HOME=C:\Path\to\Git
set PATH=%GIT_HOME%;%GIT_HOME%\bin;%GIT_HOME%\usr\bin;%GIT_HOME%\mingw64\bin;%PATH%
(Add any other path you would need)
Try then to regenerate your SSH key.
Also, make sure this is not related to an AV (Anti-Virus) as in issue 1832 or issue 1291.
My company also uses TrendMicro.
Can confirm that making an exception for /Git/usr/bin/bash.exe works as well.
For me it was C:\Program Files\Git\usr\bin, but adding it to the list of trusted programs did indeed fix the issue
I faced the same problem yesterday. Using git-bash, all my commands (i.e. mvn, javac, git pull) were giving error "Segmentation fault". This was because an update of my machine anti-virus which blocks proper access to my local login profile (sambit-swain#TERMINAL) After un-installing it, everything went back to normal.
So, the problem is not with GIT BASH or any other configuration. I should have checked the access levels (including SSH keys) to programs.
I'm using Git (and GitHub) on a daily basis and everything has been working fine and all of a sudden, I can no longer communicate with my remote GitHub repository through my Git commands. When I try to "Git pull", it gives the following error:
fatal: unable to access 'https://github.com/snahrvar/eatibl.git/':
error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert
protocol version
So, I tested across multiple repositories, and I get the same errors on my computer. I had someone else interact with those same repositories, and it works fine for them. Prior to this error, I did an "npm install sharp" on a project and that ended up failing, and I suspect this may have messed with some SSL setting, but that's a wild guess!
Any general thoughts or guidance would be much appreciated!
If it's helpful at all, here is my environment:
Git version: 1.9.4.msysgit.2
Windows version: Windows 8.1
Updating TortoiseGit and GCM didn't help me, but updating Git itself did, as per #Frederic's advice in comments.
https://git-scm.com/download/win
To make sure the new version of Git installs properly and doesn't conflict with previous installations (it might, if you used TortoiseGit's, because it would use different folders and mess with PATH variable), remove the existing Git installation before installing the updated Git. Might also need to install with administrator rights.
You're likely running into an incompatibility with GitHub's deprecation of weak SSL encryption protocols:
Weak cryptographic standards removal notice
The solution will vary, but for Windows you likely need to upgrade the Git credential manager to 1.14.0
https://github.com/Microsoft/Git-Credential-Manager-for-Windows/releases/tag/v1.14.0
If you are using Android Studio or IntelliJ IDEA, updating Git to the latest version and changing the path to point to the new version solve the problem for me.
Using TortoiseGit, I did all of the other fixes/updates given for this and still no success. I found this: Can't git push/pull/fetch suddenly
My TortoiseGit settings for Git for Windows Git.exe path was pointing to C:\Program Files (x86)\Git\bin. I changed it to C:\Program Files\Git\bin and now it's working again.
This is what worked for me.
Install the latest version of Git from here: https://git-scm.com/download/win
In TortoiseGit, go to menu Settings → General → Git.exe Path - change it from 32-bit to 64-bit path:
C:\Program Files (x86)\Git\bin → C:\Program Files\Git\bin
Updating Git was not enough in my situation. After debugging for several hours, this was my fix:
C:\wamp64\www\maandlastenmanager> git config http.sslVersion
tslv1.0
C:\wamp64\www\maandlastenmanager> git config http.sslVersion tlsv1.2
C:\wamp64\www\maandlastenmanager> git config http.sslVersion
tslv1.2
I had this same problem while pulling code from GitHub on my Visual Studio Code terminal. I found the advice in the previous answers useful and hacked a solution together following the steps below:
I updated Git.
I updated Git Credential Manager for Windows.
Made some changes to the registry.
Updated my Visual Studio Code installation to the latest version.
Changed my Windows path for Git from C:\Program Files (x86)\Git\bin. to C:\Program Files\Git\bin.
This repository was quite useful.
I hope this helps someone.
TL;DR: git config --system http.sslbackend schannel and switch off HTTPS checks for github.com in your antivirus software
I'm using the Git command line on Windows 8 x64. In addition, my antivirus software checks HTTPS traffic by default. Like other people in answering this question, I use GitHub almost daily.
Updating Git - didn't help - because I used OpenSSL (see below)
Updating credential manager - didn't help
Then I started playing with switching the SSL backend:
git config --system http.sslbackend openssl
----------------vs------------------
git config --system http.sslbackend schannel
and the antivirus software checks for SSL traffic:
OpenSSL, HTTPS checks ON: error:0407006A:rsa routines:RSA_padding_check_PKCS1_type_1:block type is not 01
OpenSSL, HTTPS checks OFF: SSL certificate problem: unable to get local issuer certificate
SecureChannel, HTTPS checks ON: schannel: next InitializeSecurityContext failed: Unknown error (0x80092012) - The revocation function was unable to check revocation for the certificate.
SecureChannel, HTTPS checks OFF: worked fine
P.S.: Instead of commandline, you can just reinstall the latest Git, selecting "Use native Windows SSL validation library".
P.P.S.: The case (3) seems to be a bug in the schannel library, because the MITM certificate my antivirus software uses is whitelisted on my machine.
On macOS, you can install the latest git via Homebrew.
Same for me with Git 1.9.5.msysgit.1 too. I tried to install https://github.com/Microsoft/Git-Credential-Manager-for-Windows/releases/tag/v1.14.0, but no change.
Actually, nothing happen after installation; maybe I'm doing something wrong? (That may not help for the initial question, but for other people, yes!)
Yeah, I encountered the same issue on a pull request today and the solution was to simply update Git by downloading the latest (2.16.2) 64-bit version of Git for Windows. It was released 5 days ago, on 2018-02-20.
The comment by #andw worked for me:
Update Git version 1.9.5 to 2.15.1 using these steps:
In sourceTree, go to menu Tools → Options → Git → Use Embedded Git.
A quick solution would be git config --global http.sslVerify true, but it is not recommended as it defeats the purpose using SSL.
A second and better way is to use ssh keys rather than an SSL URL.
Steps to generate SSH keys
o Run the following command in a Git terminal (Git Bash): ssh-keygen
After running the command, the following message will appear:
Generating public/private RSA key pair.
Enter file in which to save the key (/h//.ssh/id_rsa):
Give the path for the key to be stored in, for example, enter the file in which to save the key (/h//.ssh/id_rsa): C:\Users\Public\my-new-ssh-key
Then give the passphrase for that key (any password of minimum 8 characters)
• Next run the following command: eval “$(ssh-agent –s)”
• Run the following command: ssh-add C:/Users/Public/my-new-ssh-key Note: use forward slash in the path to the newly created SSH key.
After that, add the contents of the file my-new-ssh-key.pub and add it in the text area for Add public key (Bitbucket, GitHub, etc.)
While connecting to a remote repository to fetch, pull, push, etc., I had the same error:
fatal: unable to access 'https://github.com/repository.git/': error:1
407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version
I just reinstalled Git 64-bit in place of 32-bit and that fixed the issue.
After installation, verify the Git path in environment variables. It should be:
C:\Program Files\Git\bin\git.exe
This is an issue with IntelliJ and RubyMine. GitHub must have disabled SSL (PCI compliance maybe?) in favor of TLS. If you open Settings in IntelliJ or RubyMine and navigate to Version Control > Git, you'll see it's using a git.exe installed under the application's path. You should download the most current version of Git and change the path in your VCS settings to point to that, e.g. C:\Program Files\Git\bin\git.exe if you install it on Windows. Works like a charm after that.
Sometimes, this is caused by outdated msysgit which is using old ssl and not maintained any more, you can install latest git for windows, and point the git.exe path in tortoise setting to it, then this problem gone.
Git version upgrade did the trick for me. I had the version 1.9.5 and so and I upgraded to 2.21.0 on windows. Also upgrading is very easy. We don't need to uninstall the older version. Download the latest Git installer and just keep on pressing next using default options and the version will be changed to new version and all the old settings will still be working like ssh keys etc. We don't need to generate the keys again and put on github or any other repository.
Earlier my https protocol cloning was not working and giving error
fatal: unable to access 'https://github.com/tensorflow/models/':
error:1407742E: SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert
protocol version
Once I downloaded new version and ran the same clone command it worked without any issues.
I also came across to this problem recently
What worked for me was to revert an automatic update of git
Encountered a similar error.
On windows, Updated git on windows to the latest version.
That fixed the problem.
I'm trying to use Git Extensions on a new Windows 7 machine. I have done that many times before but never hit this particular issue.
Git Bash is working, I successfully cloned a repository.
But going to Git Extensions, opening the repo, and doing a pull gives me the following error message:
"C:\Program Files (x86)\Git\bin\git.exe" pull --progress "origin"
error: cannot spawn git: Function not implemented
Done
Press Enter or Esc to close console...
My setup is very ordinary. The Git Extensions startup checks all pass. (This is similar but not the same problem as the common invalid path issue.)
Do you have any idea what causes this problem?
The new releases, Git for Windows 2.16.1(3) and Git for Windows 2.16.1(4), fix this regression:
2.16.1(3) Bug Fixes
When http.sslBackend is not configured (e.g. in portable Git or MinGit), fetch/push operations no longer crash.
On Windows 7 and older, Git for Windows v2.16.1(2) was no longer able to spawn any processes (e.g. during fetch/clone). This regression has been fixed.
The Perl upgrade in v2.16.1(2) broke git send-email; This has been fixed by updating the Net-SSLeay Perl module.
The mentioned regression in the second bullet point is exactly the error this question is about.
Unfortunately, there was one missing issue about spawning processes which was then fixed in the subsequent fourth release:
2.16.1(4) Bug Fixes
When called from TortoiseGit, git.exe can now spawn processes again.
Note that the download on https://git-scm.com/download/win might not have been update yet, so you need to download it from gitforwindows.org or directly from the release page on GitHub.
Afterwards, you can verify that you indeed running the new version using git --version which should report git version 2.16.1.windows.4.
Per Philippe and Jake - bug is filed against GIT 2.16.2, and workaround is to go back to prior version.
https://github.com/git-for-windows/git/releases/tag/v2.16.1.windows.1
Running an update on my machine to Git for Windows v2.21.0- just a slightly updated version fixed the issue with my Windows 7 installation at work.
https://github.com/git-for-windows/git/releases/download/v2.21.0.windows.1/Git-2.21.0-32-bit.exe
I am very new to the terminologies: git, repository and cloning.
I was able to search them all online and get pretty good grip on each (pretty simple stuff!).
But what I am trying to figure out now is how to "run" these instructions:
Clone repository for app:
git clone git://github.com/SampleLink.git
Update submodules:
git submodule update --init
I am running Windows7. I tried to run init through command prompt, but no luck.
Are these supposed to be run as individual commands or as one following the other in sequence automatically?
I am just not sure how to run these on my Windows machine and cannot seem to get any of it to work.
The submodule is a file within the initial repository.
I'm sorry if this is a lame question, but I have never needed to run this type of setup before.
I would recommend installing msysgit in its "Git for Windows" instance:
Git-1.7.3.1-preview20101002.exe
I like using Option 2, only adding the git\bin directory to the PATH environment variable, but without overriding some built-in windows tools.
From there, git clone over http should work.
