How to fix 'packet_write_wait: Connection to ... Broken pipe' error in Git

Question

How can I fix the problem when I git push files to my remote repositories and it throw the error 'packet_write_wait: Connection to 13.250.177.223 port 22: Broken pipe'?Before git push, I had clone the project from the remote and git add, git commit successfully.

I haved tried git pull, git config http.postBuffer 52428800, but it doesn't work.

Answer 1

What worked for me in the context of pushing my repo to github was adding IPQoS=throughput to my config file in ~/.ssh/config. The other steps for making sure SSH is are set up correctly, added to your Github account etc. are detailed here

Answer 2

Make sure your SSH URL for your remote origin does work:

ssh -T yourServer

Its IP address should not change.

See if the issue persists with the latest Git for Windows (PortableGit-2.20.1-64-bit.7z.exe), uncompress in C:\Git, and set a simplified PATH in a CMD session.

set PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\
set GH=C:\path\to\git
set PATH=%GH%\bin;%GH%\usr\bin;%GH%\mingw64\bin;%PATH%

Note: you can see arror messages with packet_write() failing.
Before, we gave an extra error message unnecessarily, which has been corrected with Git 2.32 (Q2 2021).

See commit 332ec96 (15 Apr 2021) by Matheus Tavares (matheustavares).

pkt-line: do not report packet write errors twice

^{Signed-off-by: Matheus Tavares}

On write() errors, packet_write() dies with the same error message that is already printed by its callee, packet_write_gently().
This produces an unnecessarily verbose and repetitive output:

error: packet write failed 
fatal: packet write failed: <strerror() message>  

In addition to that, packet_write_gently() does not always fulfill its caller expectation that errno will be properly set before a non-zero return.
In particular, that is not the case for a "data exceeds max packet size" error.
So, in this case, packet_write() will call die_errno() and print an strerror(errno) message that might be totally unrelated to the actual error.

Fix both those issues by turning packet_write() and packet_write_gently() into wrappers to a common lower level function that doesn't print the error message, but instead returns it on a buffer for the caller to die() or error() as appropriate.
