When opening Git Bash I get the following error:

Error: could not fork child process: Resource temporarily unavailable (-1). DLL rebasing may be required. See 'rebaseall / rebase --help'.

When I press enter Git Bash closes. I've tried reinstalling, installing different versions, restarting, and nothing seems to help.

Could you quickly try installing Cygwin and see whether it runs?

[hwallace90]

It did not, same error. I installed Cygwin with all the defaults. At the end it did show this, which I thought was noteworthy given the issue I'm facing:

[dscho]

That is what I feared. Those errors come from the MSYS2 runtime, which is itself a friendly fork of the Cygwin runtime. Meaning: whenever Cygwin updates, we update, too.

Could you try previous Git for Windows versions to see whether they demonstrate the same problem, or whether it is a regression in the newest version?

[hwallace90]

I've tried several different versions, one much older (1.9.2), a few more recent, all the same error. Just to double check, I just installed 2.9.2, same error.

[dscho]

Hrm. Maybe you one of those applications installed? https://cygwin.com/faq/faq.html#faq.using.bloda

[hwallace90]

Correct, this is a work computer at a large corporation with McAfee installed and I'm sure other firewalls and things of that nature. Other coworkers are not having the same issues I am strangely enough. I will escalate internally to see if I can get any assistance. This is my nightmare D: . Thank you for the information.

[dscho]

McAfee is not on the BLODA list, but maybe you can identify another "dubious" application (such as PowerBroker) that is running in your setup?

[hwallace90]

Luckily for me, I come into work today and it is now working. It being a work computer, some update must have been pushed that now allows it to work. Weird experience, thank you for the information and assistance though.

@hwallace90 let's close it until the day it resurfaces?

I had exactly the same error which I managed to fix. I'm adding these details in case anyone else has the same problem. It fails on one PC but is OK on two others. The only software I have installed that is on the BLODA list is Windows Defender but I tried disabling this temporarily with no change. An uninstall and reinstall also failed to solve the problem. All PCs are running Windows 10.

I managed to finally fix it by running C:\Users\USERNAME\AppData\Local\GitHub\PortableGit_d7effa1a4a322478cd29c826b52a0c118ad3db11\post-install.bat from an elevated command prompt. It showed a couple of errors but everything seems to be working fine afterwards.

This seems to be GitHub Desktop rather than Git for Windows. But I'm glad you were able to get to the bottom of it.
