connecting to github repo from server: success for 1-9, error for 10 only

[buffler]

First of all, this is an awesome sanity checker - thank you tons for providing it!

I keep running into the following error when running bundle exec cap staging deploy:

Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

I have a feeling this is going to end up being an issue on my end, not yours, but: have you ever seen numbers 1-9 succeed but 10 still fail, when trying to connect to a Github repo from a staging server? Here's the output when running bundle exec cap staging ssh:doctor:

SSH agent forwarding report
---------------------------
1. [success] `repo_url` setting ok
2. [success] ssh private key file exists
3. [success] `ssh-agent` process seems to be running locally
4. [success] `ssh-agent` process recognized by `ssh-add` command
5. [success] ssh private keys added to `ssh-agent`
6. [success] application repository accessible from local machine
7. [success] all hosts using passwordless login
8. [success] `forward_agent` ok for all hosts
9. [success] ssh agent successfully forwarded to remote hosts
10. [error] It seems Capistrano cannot access application git repository from these hosts:
ssh.phx.nearlyfreespeech.net
Actions:
- make sure all the previous checks pass. That should make this one work too.

This happens when using the format

set :repo_url, '[email protected]:{github-organization}/{private-repo}.git'

in my deploy.rb. When using either

set :repo_url, 'https://{github-username}:{github-password}@github.com/{github-organization}/{private-repo}.git'

or

set :repo_url, 'https://{github-oauth-token}:@github.com/{github-organization}/{private-repo}.git'

, I am able to successfully connect to the Github repo from the staging server - but those are less than ideal as (I think) they'd require putting Github credentials of some sort in the repo.

I'm admittedly not super strong re: ssh-agent, forwarding, etc. so I'm sure there are a few things I could be missing. I am encouraged to know that having checks 1-9 pass should make 10 work too, but perplexed as to what else might be causing check 10 to fail. Thanks for any insight/assistance you may be able to provide!

I've set this up currently so that my Github oauth token is in a separate, gitignored file, which is then required in my Capistrano deploy.rb file to put the repo_url together. So, I can now successfully deploy to our staging server without including sensitive information in the repo.

I'd still like to find out why I can't use the [email protected]:{github-organization}/{private-repo}.git format for :repo_url, with keys, when all of the SSH forwarding report's requirements seem to be met. If you need further info from me just let me know - and thanks again for any help!

I'm having exactly the same issue, only thing is that I'm using gitlab.com istead of github.
Also is @buffler temporary fix not working for me:

[6656b180] remote: HTTP Basic: Access denied DEBUG [6656b180] fatal: Authentication failed for 'https://OAUTH:@gitlab.com/NAME/NAME.git/'

[cce6eb0e] fatal: unable to access 'https://NAME:PASSWORD/[email protected]/NAME/NAME.git/': Couldn't resolve host 'NAME'

Same issue with set :repo_url, '[email protected]:{github-organization}/{private-repo}.git'

1. [success] `repo_url` setting ok

2. [success] ssh private key file exists

3. [success] `ssh-agent` process seems to be running locally

4. [success] `ssh-agent` process recognized by `ssh-add` command

5. [success] ssh private keys added to `ssh-agent`

6. [success] application repository accessible from local machine

7. [success] all hosts using passwordless login

8. [success] `forward_agent` ok for all hosts

9. [success] ssh agent successfully forwarded to remote hosts

10. [error] It seems Capistrano cannot access application git repository from these hosts:

Actions:
- make sure all the previous checks pass. That should make this one work too.

I had some weird issues like this. As soon as I used bundler i.e. bundle exec cap staging deploy it no longer prompted me for a ssh password and continued to work again.
