推送远程仓库（github/gitlab） 报错：Host ke

本地往远程仓库推送时报错

起因公司给配的电脑坏了，但是苹果的iCloud可以同步，在新电脑上一番配置后，发现本地的代码没法推到远程仓库：

做过的一些配置：

1. 本地仓库的远程仓库地址
2. ssh密钥对
3. 在远程仓库上github/gitlab上也已经添加了本地密钥

报出以下的错误：

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

Host key verification failed.
fatal: Could not read from remote repository.

解决办法：

方法一：
ssh-keyscan -H github.com >> ~/.ssh/known_hosts

方法二：
ssh -T git@gitlab.com 待确认时输入yes
