執行 yum 更新時的依賴關係問題
當我嘗試進行 yum update 時，遇到了問題，你能告訴我問題出在哪裡嗎？

我嘗試了很多命令，發現以下命令非常有用。
# yum update --disableexcludes=main
我認為您的系統用於更新儲存庫的元數據已過時。
由於找不到對應的
perl-Git包更新，更新失敗。但是，我檢查了我本地的 CentOS 鏡像，並且那裡有正確的更新包。因此，我懷疑您的更新儲存庫的元數據有些舊。我建議您清除元數據，然後再次嘗試更新。
yum clean metadata如果仍然失敗，則問題可能出在鏡像上，而不是您的系統上。在這種情況下，只需等待 24 小時，以便鏡像恢復同步。
