Hi, I’m having this issue in the **checkout code** step. It was working fine until a few days ago. Now it gets stucked there, asking for user input.

It’s weird to get this error on the checkout right? I saw the log of the checkout code step and it adds the ssh-rsa of github to the know\_hosts.

Also the checkout SSH deploy key permission is set.

This is the log:

```
Using SSH Config Dir /.ssh
Cloning into '.'...
The authenticity of host 'github.com (140.82.113.4)' can't be established.
RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)? 

```

Any help is welcome 🙂  
Thanks!

Hi @felipe - can you confirm when this job was run, and if you are attempting to rerun it? There was a small interruption with checkout commands on Friday that affected a small number of checkouts - [https://status.circleci.com/incidents/y96b8jc4m9bx](https://status.circleci.com/incidents/y96b8jc4m9bx). Pushing a fresh commit should allow the job to run normally 🙂

I’ve pushed a lot of commits yesterday with different attempts to fix this. Strange thing is that when I’ve added a step with such a command before `checkout`:

`mkdir ~/.ssh && touch ~/.ssh/known_hosts && ssh-keyscan github.com >> ~/.ssh/known_hosts`

it’s output was:

```auto
# github.com SSH-2.0-babeld-76c80caa
# github.com SSH-2.0-babeld-76c80caa
no hostkey alg

```

Hi! Thank you for your reply @gmemstr

The problem started 4 days ago, but the error is still happening. I just created a new branch, a new commit and pushed it, but it failed with the same error.

I will copy all the log of the checkout step.

```
#!/bin/sh
set -e

# Workaround old docker images with incorrect $HOME
# check https://github.com/docker/docker/issues/2968 for details
if ["${HOME}" = "/"]
then
  export HOME=$(getent passwd $(id -un) | cut -d: -f6)
fi

I just ended changing my circleci config.yml to get the tests working again.

My workaround was changing the base images.

I changed:

```
  docker
    - image: ruby:2.1.1
    - image: circleci/mysql:5.6.38-ram

```

to this:

```
docker:
  - image: circleci/ruby:2.1
  - image: circleci/mysql:5.6.38-ram

```

I don’t really know why this change makes the script checkout not to fail. I supposed that is something related to the context of the base image.

Hope this helps you.
