Private Repositories bug

Bug description

I am trying to build my Unity Project to Android using the GameCI. My project uses private repositories with ssh. I follow the documentation and I put the SSH Agent step in my CI. I add the Deploy Key to my repository and add the secret key to Secrets.

But this error occurs:

com.company.utils: Error when executing git command. Failed to add the RSA host key for IP address '140.82.112.3' to the list of known hosts (/root/.ssh/known_hosts).
    ERROR: Repository not found.
    fatal: Could not read from remote repository.

I already try to add the ips in /home/runner/.ssh/known_hosts. The command below does not return errors:

Run ssh-keyscan 140.82.114.3 >> /home/runner/.ssh/known_hosts
  ssh-keyscan 140.82.114.3 >> /home/runner/.ssh/known_hosts
  shell: /usr/bin/bash -e {0}
  env:
    SSH_AUTH_SOCK: /tmp/ssh-BYQRT89SNPb3/agent.1664
    SSH_AGENT_PID: 1665

# 140.82.114.3:22 SSH-2.0-babeld-968490c5

When I try to add to /root/.ssh/known_hosts, the error occurs:

Run ssh-keyscan github.com >> /root/.ssh/known_hosts
  ssh-keyscan github.com >> /root/.ssh/known_hosts
  shell: /usr/bin/bash -e {0}

Error: Process completed with exit code 1.

How to reproduce

• Create a unity project that uses private repositories with ssh

• Try to run CI Unity Build

Expected behavior

Build the project with success

If you have access to sudo, maybe you can try | sudo tee -a like this:

# ...
      - name: Adding github to known_hosts
        run: ssh-keyscan github.com | sudo tee -a /root/.ssh/known_hosts

      - name: Adding github to known_hosts
        run: ssh-keyscan 140.82.114.3 | sudo tee -a /root/.ssh/known_hosts

      - name: Adding github to known_hosts
        run: ssh-keyscan 140.82.114.4 | sudo tee -a /root/.ssh/known_hosts

I just confirmed that this fixes the permission issue you’re getting:

com.company.utils: Error when executing git command. Failed to add the RSA host key for IP address ‘140.82.112.4’ to the list of known hosts (/root/.ssh/known_hosts).

ip is 140.82.112.4 in above error message, but the ones you are adding here are different:

      - name: Adding github to known_hosts
        run: ssh-keyscan github.com | sudo tee -a /root/.ssh/known_hosts

      - name: Adding github to known_hosts
        run: ssh-keyscan 140.82.114.3 | sudo tee -a /root/.ssh/known_hosts

      - name: Adding github to known_hosts
        run: ssh-keyscan 140.82.114.4 | sudo tee -a /root/.ssh/known_hosts

I know they’re close, but there’s a small difference:

140.82.114.3 140.82.114.4 140.82.112.4 <-- the ip from your error

😉

Try also adding this maybe?

      - name: Adding github to known_hosts
        run: ssh-keyscan 140.82.112.4 | sudo tee -a /root/.ssh/known_hosts
