我刚刚将Vagrant VM从一台主机复制到另一台主机。两台机器都运行Windows 7。

尝试访问Github时，我将VM复制到的机器上出现以下错误。

该仓库肯定存在，我在原始机器上具有完全相同的Git配置。为什么会这样？对于此错误，最重要的答案对我没有影响。

[vagrant@localhost /var/www/wrestlemaniamainevent]# git remote -v

origin  git@github.com:crmpicco/wrestlemaniamainevent.git (push) 
 
[vagrant@localhost /var/www/wrestlemaniamainevent]# git fetch origin 
ssh: connect to host github.com port 22: Network is unreachable

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

请您参考如下方法:

首先，您是否从新主机验证了它不是网络问题，是否可以从新主机上的vm ping github？

第二个，如果ssh有问题(并且您不是像我这样的网络专家，它可能是新主机上的防火墙问题...)，则可以更改为使用https版本

run `git config --local -e`
