linux上使用publickey访问gerrit异常

现象

redhat上，先使用A账号，能正常执行相关操作。切换成B账号，上传public key后，执行异常：

Agent admitted failure to sign using the key.
Permission denied (publickey).
fatal: Could not read from remote repository.

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

解决办法

执行完ssh-keygen再执行一下ssh-add

ssh-keygen -t rsa -C "mymail@my.com"
ssh-add ~/.ssh/id_rsa
