git - 替换到另一台 PC 后无法推送到 github repo

Question

我正在开始我的项目并使用 github 进行远程 repo 。

我将操作系统从 Ubuntu 更改为 Xubuntu。

但是我将所有旧文件都复制到了新位置。

我继续使用我需要 push 更改的程序。

我生成了新的 SSH key 并添加到了 github。

我试图推送更改，但它打印出奇怪的信息:

nazar@nazar-desctop:~/Documents/workspace/NewYearGift$ git status
# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
#
nothing to commit (working directory clean)
nazar@nazar-desctop:~/Documents/workspace/NewYearGift$ sudo git push -u origin master
[sudo] password for nazar:
ssh: Could not resolve hostname github.com: Name or service not known
fatal: The remote end hung up unexpectedly

更新:

我再次重新创建了这个项目，现在它询问我的密码:

nazar@nazar-desctop:~/Documents/workspace/NewYearGift$ git commit -m "correct smole issue"
[master e2cbdec] correct smole issue
 1 file changed, 29 insertions(+), 29 deletions(-)
 rewrite README.md (89%)
nazar@nazar-desctop:~/Documents/workspace/NewYearGift$ git push

现在它有效，但为什么这么严格？

smb能解释一下吗？

如何解决这个麻烦？

Answer 1

Could not resolve hostname github.com: Name or service not known

您需要修复系统的解析器。由于某种原因，它无法解析 github.com 的 IP 地址
