git pull fatal: Could not read from remote repository

Atlassian Stash v2.10.1


$ git pull
fatal: Could not read from remote repository.

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

 

$ ssh -p 7999 git@<stash-server>

shell request failed on channel 0

 

So not an ssh/authentication issue.    Was working yesterday, not working this morning, working this afternoon, not working this evening.

What could it be?

Thanks.

Under load, Stash may be unable to handle all requests in an elegant way.

Thank you, Thiago and Balazs, for your help.

Hi Tyler,

It seems that you have a SSH key uploaded but no read access to the repository in Stash as per the error below:

$ git pull
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

To solve that, please talk to your Stash admin so you can be assigned the right permissions.

The error below is expected because it should not be possible to get a remote shell via Stash (we use http://mina.apache.org/sshd-project/index.html for our SSH server):

$ ssh -p 7999 git@&lt;stash-server&gt;
shell request failed on channel 0

Please refer to https://jira.atlassian.com/browse/STASH-3372

Best,
Thiago

The admin has not being revoking, then reissuing the access permissions. Thanks.

Hi Tyler. I am glad that this answer has helped you and you found the culprit ;)

Since you say "Was working yesterday, not working this morning, working this afternoon, not working this evening", I doubt that Thiago is right about your user rights. (He might be right, but then somebody took your rights away to the repo, gave them back and took them away again.)

Try these:

  • If you can browse the contents of the repo on the Stash web interface, you can connect to Stash and do have at least read rights, so the issue is probably with the SSH connection.
  • If the above works, check that your SSH public key is correct in your profile (http://<stash server>/plugins/servlet/ssh/account/keys) and that your SSH agent is running on your machine and has your key loaded.
  • If all of these are OK, you might have a firewall on your computer or somewhere else blocking the connection to Stash.

Confirmed, I can browse the contents of the repo on the Stash web interface. The "shell request failed on channel 0" proves there is nothing wrong with the network (server accessibility) or the ssh authentication. We are exploring a possible loading issue (tens-of-thousands of accesses, yesterday, from a CI server).

I have this same error per now. It worked earlier but not now.

I can clone using https, but not ssh. The error shown is the same as presented in this question...

 

In bitbucket.log there is this:

 

2017-10-09 18:12:52,988 INFO  [ssh-scm-request-handler] jenkins @XQ6B4Fx1092x38x0 1p1nx9x 127.0.0.1 SSH - git-upload-pack '/lif/com.liferay.portal.plugins.sdk-7.0.git' c.a.b.i.ssh.server.SshCommandAdapter git was successfully authenticated via public key, but is no longer active in the underlyinguser directory. The request has been blocked

 

I'm pretty sure the OP would have had something similar in Stash back then...
