git - Automating access to Bitbucket private repo -

when add git pull origin master auto-deploy script private repo, i'm given error:

fatal: not read password 'https://someone@bitbucket.org': no such device or address 

the ssh key server granted access bitbucket account, why produce error?

without seeing git pull command, assume using git clone https://someone@bitbucket.org/someone/repo.git - uses basic authentication on https not ssh keys. using https access repo requires username/password.

in order use ssh key auth, have use ssh repo access command like: git clone git@bitbucket.org:someone/repo.git
