bitbucket.org: Permission denied (publickey)

Question

I want to perform git clone from bitbucket.org

git clone [email protected]:mascai/regru_junjob.git

Received error:

Cloning into 'regru_junjob'... Warning: Permanently added the RSA host key for IP address '2406:da00:ff00::34cc:ea4a' to the list of known hosts.

Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.

I add pub and private keys to my server:

~/.ssh# ls
authorized_keys  id_rsa.pub  known_hosts  reg_jj  reg_jj.pub

Added pub key to the bitbucket.org https://bitbucket.org/mascai/regru_junjob/admin/access-keys/

What is the reason of the error?

May be usefull

~# ls -la ~/.ssh/

Answer 1

Using the command ssh -Tv [email protected] suggested by @phd, I was able to figure out the issue. It was indeed, a permissions issue

Permissions 0664 for '/home/ubuntu/.ssh/id_rsa' are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.
