[Bug]: Git clone failed (SSH only, HTTP is OK)
Problem description
Cloning a Git repo would fail if using SSH. HTTP cloning does NOT have this issue. I have tried this on another phone (arm) and I had the same issue.
What steps will reproduce the bug?
~ $ git clone [email protected]:termux/termux.github.io.git Cloning into 'termux.github.io'... remote: Enumerating objects: 1378, done. remote: Counting objects: 100% (341/341), done. remote: Compressing objects: 100% (156/156), done. remote: Total 1378 (delta 252), reused 185 (delta 185), pack-reused 1037 (from 3) Receiving objects: 100% (1378/1378), 1.84 MiB | 2.54 MiB/s, done. Resolving deltas: 100% (688/688), done. error: ssh died of signal 6 fatal: remote transport reported error
However, when cloning with HTTP (success): ~ $ git clone https://github.com/termux/termux.github.io.git Cloning into 'termux.github.io'... remote: Enumerating objects: 1378, done. remote: Counting objects: 100% (341/341), done. remote: Compressing objects: 100% (156/156), done. remote: Total 1378 (delta 251), reused 185 (delta 185), pack-reused 1037 (from 3) Receiving objects: 100% (1378/1378), 1.84 MiB | 2.99 MiB/s, done. Resolving deltas: 100% (687/687), done.
What is the expected behavior?
Git cloning should succeed with SSH or HTTP.

Just wanted to add some additional info. On the same device, if I run git within a proot-distro, git can clone successfully.

This might be a dumb question but I gotta ask it anyway...
The openssh package is installed on both devices you tried this on, correct?
You can't use the SSH protocol for cloning without an ssh client.
Yep, openssh was installed in Termux and proot-distro (ubuntu).
~ $ apt -qq list openssh openssh/stable,now 10.2p1 arm [installed]
root@localhost:~# apt -qq list openssh-client openssh-client/questing,now 1:10.0p1-5ubuntu5 armhf [installed,automatic]
Unfortunately, I am not able to reproduce this on Samsung Galaxy S III SPH-L710. Therefore, there must be an unknown device-specific factor involved with this issue.
This is what I see

Samsung Galaxy S III SPH-L710 is 32-bit ARM and has Android 7.
I have just tested the same steps again on Samsung Galaxy A70 SM-A705FN, which is 64-bit ARM and has Android 13, and the problem is also not occurring on that device either.
Thanks for looking into it @robertkirkman . I think you are just missing a public key setup on Github.
In the meantime, I'll try the gh command to see if that works for me.
EDIT: sorry I mis-read your message earlier, you did use git to clone.
Unfortunately, that the gh repo clone does not work for me either.

I am not sure what I am missing...
My phone is a Galaxy S5 Neo (running LineageOS 18.1):
~ $ uname -a Linux localhost 3.10.108-ge773f94621d #1 SMP PREEMPT Sun Nov 28 12:47:34 CET 2021 armv8l Android
Does the ssh command work for you to connect to a normal SSH server, or is it possible for you to reproduce the same problem by just using the ssh command to connect to a normal SSH server without involving git?
I did notice something:
If I ssh to GitHub from my phone, I get this extra line that says "Aborted":
~ $ ssh -T [email protected]
Hi brianwoo! You've successfully authenticated, but GitHub does not provide shell access.
Aborted ssh -T [email protected]
From my computer, I do not have that line showing in my terminal.
