电脑升级系统以后会出现秘钥失败
Host key verification failed.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
这个时候需要重写ssh，必要的话删除.ssh文件夹
执行下面3行即可
ssh-keygen -t rsa -f tapas_gerrit
ssh-keygen -t rsa -C "xxx@xx.com"
cat ~/.ssh/id_rsa.pub
ssh-keygen -t rsa -C "xxx@xx.com"
cat ~/.ssh/id_rsa.pub
