SSH connection problem between Bitbucket and Ubuntu 14.04

[DimaP]

Hi community,

I try to use SSH to clone repository from Ubuntu 14.04 without any success. The same repository is cloned using WIN10 (via Sourcetree app)

Bitbucket is unaccusable via Firefox, I got "Something went wrong" message (error code: 77ee9a4077b9488b93b0e310c7438f59).

When I ping Bitbucket via"ping www.bitbucket.org" I have no ping problems via Ubuntu.

To config the connection, I performed the steps in the link:

https://support.atlassian.com/bitbucket-cloud/docs/set-up-personal-ssh-keys-on-linux/

On testing the connection via "ssh -T git@bitbucket.org" command I got:

cisys@cisystems-HP-EliteDesk-800-G1-TWR:~/.ssh$ ssh -T git@bitbucket.org
/home/cisys/.ssh/config: line 2: Bad configuration option: addkeystoagent
/home/cisys/.ssh/config: terminating, 1 bad configuration options

So I deleted the line "AddKeysToAgent yes", so it won't throw any error, but the "ssh -T git@bitbucket.org" command is stuck (no answer is returned)! Entering the command "ssh -vT git@bitbucket.org" (with 'v' flag) throw me the following data, but still stuck on the last line:

EliteDesk:~$ ssh -vT git@bitbucket.org

What can solve the issue?

Welcome to the community!

Based on the issue you faced with SSH, I suspect that it's because you are using an outdated SSH version. As a start, I suggest updating your SSH version to the latest and see if that helps.

I also suggest cloning via HTTPS if updating your SSH is impossible as a workaround.

As for the Firefox issue, I can see that the error translates to a browser issue. Knowing that you have an outdated version of SSH, I highly suspect that the Firefox version is outdated and doesn't play well with Bitbucket. You might need to update the Firefox version or use a different web browser.

I hope this helps.

Hi, 

Thanks for the reply. I get the same message when i try to connect via Win10 machine (it hangs on the last message):

is it possible that the reason is Firewall?

Thanks

Can you try cloning via HTTPS to see if that works?

Additionally, when cloning via SSH, please try using the following verbose commands log to see if there's any error:

GIT_TRACE_PACKET=1 GIT_TRACE=1 GIT_SSH_COMMAND="ssh -vvv" git clone <URL>

Cloning via HTTPS is working, in addition i can work with Sourcetree app (HTTPS  based).

The issue for me is that some of the sources compiled on WIN (so the HTTPS is good enough), but some of the sources must be compiled on Linux (Nsight Eclipse IDE) and SSH is required.

The command output you suggested is:

GIT_TRACE_PACKET=1 GIT_TRACE=1 GIT_SSH_COMMAND="ssh -vvv" git clone git@bitbucket.org:ci-systems-metcam/metcam.app.git

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

Finally the reason was found, there were IT firewall policies that caused this issue. 

D:\xxxxxxx>git clone git@bitbucket.org:xxxxxxxxxx/xxxxxxxx.app.git
Cloning into 'xxxxxxx.app'...
The authenticity of host 'bitbucket.org (104.192.141.1)' can't be established.
