Permission denied (publickey,gssapi-keyex,gssapi-with-mic) on openshift

Question

I am having issues with committing changes to my gear. I have tried to run rhc setup, I also deleted my .ssh folder and executed rhc setup again but that also didnt work.

Not sure what changed but it worked couple of hours ago.

>git push -u <GEAR_NAME> master
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
fatal: Could not read from remote repository.

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

>git remote add devstage3 -f ssh://<GEAR_ID>@<GEAR_NAME>-<GEAR-DOMAIN>.rhcloud.com/~/git/<GEAR_DOMAIN>.git/ 

Also I have tried to start a different gear and commit to it but I am getting the same error:

Updating <GEAR_NAME>
The authenticity of host '<GEAR_NAME>-<GEAR-DOMAIN>.rhcloud.com (<GEAR_IP>)' can't be established.
RSA key fingerprint is <KEY_FINGERPRINT>.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '<GEAR_NAME>-<GEAR-DOMAIN>.rhcloud.com,<GEAR_IP>' (RSA) to the list of known hosts.
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
error: Could not fetch <GEAR_NAME>

Answer 1

Remove the keys: rhc sshkey-remove You can also delete them from the management console, by going to https://openshift.redhat.com/app/console/settings

Once done, upload the public key (copy the content of your id_rsa.pub to management console) : https://openshift.redhat.com/app/console/keys/new

Save it. After this try to git clone and it should work for you.

Answer 2

if you are using Windows, you can try the following steps:

1. look for your ssh public key usually you can find it at c:\\users\\YOUR_USERNAME\\.ssh

2. copy your openshift public key to your git's ssh-key folder

   suppose we have git in d:\\git

   then we need to copy the public key from c:\\users\\YOUR_USERNAME\\.ssh to d:\\git\\.ssh

3. try if it works

Answer 3

what worked for me was to generate the keys using Git Bash

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

and then add the key to ssh-agent as described here

Answer 4

Had the same issue and wasted hours, I'm using centos 7. The following solved my problem.

On linux:

1. "cd /home/your_username/.ssh"
2. View "id_rsa.pub" and copy contents
3. On openshift create a key from the UI and paste the contents from your "*.pub" file
4. Save your new key
5. Try reconnecting from your local machine

Hope the above helps. Note, on mac it worked from the word go only linux game me errors.

Answer 5

I would also recommend trying to SSH in first. With SSH use the -vv flag to show more of the connection information. My guess is that SSH is trying to use a different key than what you uploaded to the server

Answer 6

please check if you have changed to another account.

i encountered this problem when my account changed to root.

I am using ubuntu.

I solved this problem by the following cmds

rm ~/.openshift/ -rf
rm ~/.ssh/* -rf
rhc setup

and i encountered the following error:

chmod: 更改".git/FETCH_HEAD" 的权限: 不允许的操作

solved by :

sudo chmod 777 .git/FETCH_HEAD

then:

git pull

got:

Already up-to-date.

everything goes find.

Answer 7

you have to check in ~/.ssh/ if exists a file id_rsa.pub and id_rsa if not you have to create it using openssh or if exists a file with extension .pub duplicate it and rename the copy as id_rsa.pub then do the same with id_rsa. this work with google compute engine. I've tried

Answer 8

Also make sure your ~/.ssh/id_rsa file has proper permissions required by rhc:

chmod 600 ~/.ssh/id_rsa

Answer 9

The following answer might be helpful. Add GSSAPIAuthentication no into .ssh/config

$ cat .ssh/config
Host *
  ServerAliveInterval 240
  GSSAPIAuthentication no

Answer 10

I fixed the problem by setting up proxy for ssh: ~/.ssh/config

ProxyCommand /bin/connect.exe -H proxy:8080 %h %p

Host rhcloud.com
User myemailasrhclogin@gmail.com
Port 22
Hostname rhcloud.com
IdentityFile "C:\users\username\.ssh\id_rsa"
TCPKeepAlive yes
IdentitiesOnly yes

SSH in git behind proxy on windows 7

My initial mistake was to use appname.rhcloud.com as Host or Hostname. And yes, adding your public key to OpenShift is also necessary.

Answer 11

I had Permission denied (publickey,gssapi-keyex,gssapi-with-mic)
when cloning with git clone ssh://<<repo_created_by_openshift>>.

App was created with Openshift's website, not with rhc app create.
My SSH key was ok, reimporting it to Openshift didn't help, nor did expiring sessions, and so on.
I didn't want to generate a new key.

What finally worked was using:
rhc git-clone -a <app_name>> instead of bare git clone <<repo_address>>.
You may have to expire sessions as well.

Answer 12

On Windows, removing host record in Windows Credential manager helped me. After it, git became require password of my ssh key.
