SSH connection Hosting server to Bitbucket : Host key verification failed.

[Jeremy Armengaud]

Hi,

I am trying to push my initial commit from my repo on my hosting server to my central repo on bitbucket via : git push -u origin master ==> NOK

Result : Host key verification failed.

Then I try to verify my SSH connection between my hosting server and bitbucket.

To do so I connect via SSH to my hosting server ==> OK

$ ssh -T xxx@uk21.siteground.eu -p 18765

from there I attempt a ssh connection to bitbucket ==> NOK

ssh -v git@bitbucket.org

I would be grateful for any advice.

This last line:

debug1: read_passphrase: can't open /dev/tty: No such device or address

as well as this line near the beginning of the session:

Pseudo-terminal will not be allocated because stdin is not a terminal.

both suggest that your key has a passphrase, and that you're trying to use the key someplace where you are unable to provide the passphrase. Is that the case here?

I have the same issue and my sshkey does not have passphrase.

In the interest of time, you might want to try regenerating a new host key 

ssh-keygen -R bitbucket.org

This command to remove entries from known_hosts

When you try an connect it again it should rewrite it.

Going off of the following error:

debug1: read_passphrase: can't open /dev/tty: No such device or address
Host key verification failed.

Hello Team, I am sure why are you are seeing this issue. Can you increase the debug level

ssh -vvv git@bitbucket.org 

This should show us what is going on.

Thanks
