从 EC2 ubuntu 推送到 github

Question

when I run the following it seems successful:

$ sudo ssh -T git@github.com
Hi x! You've successfully authenticated, but GitHub does not provide shell access.

However, when I do a sudo git push from my repo, it doesn't work I get

Permission denied (publickey).
fatal: The remote end hung up unexpectedly

Can anyone help here?

Answer 1

The facts that you are running that on EC2 shouldn't matter at all. You are facing here an issue of an incorrect setup of ssh key and/or initially cloning the repo with the wrong user.

Whatever you do, there should be absolutely no need to use sudo. You should be able to clone the repo using an ordinary user. If that doesn't work, make sure to generate a new ssh key for this user and add it to the repo. If

ssh -T git@github.com

is working again for this user, try to clone the repo again. If that works, check if you can push to it.

If you are still running into problems, make sure you followed the install guide for Linux provided by GitHub . Everything written there works also on an Ubuntu version without graphical frontend.

I was having this same issue on my AWS EC2 Ubuntu instance and I just ended up solving it with a push in the right direction from this blog post .

What was happening for me was that root had access to the folder I was trying to clone into.

drwxr-xr-x 2 root root 4096 Apr 25 00:51 sites

Because of that, I had to do a sudo git clone... command because I didn't have write permissions to that folder as my default user.

All I needed to do was give myself write access to the /sites folder

sudo chown -R ubuntu /sites

Which allowed me to omit the sudo in the git clone... command, which ran the git command as the user ubuntu .

This fixed it for me, and I think it's cause the files in my ~/.ssh folder were owned by ubuntu , and it had to be that user running the command.
