解決「在 Fedora 更新 Chrome 失敗」問題（一）

前幾天更新時，Google Chrome 發生更新失敗。之前也沒有碰過，先把它略過，再找時間處理。這幾天剛好有空，就試試看能否找出發生了什麼問題。

請參考另一篇發文：解決「在 Fedora 更新 Chrome 失敗」問題（二），
本篇留做備用方法。

在終端機中下達更新命令，出現如下的錯誤訊息：

[root@Celeron-D ~]# yum update google-chrome

由訊息末端可以判斷，應該是某個『認證金鑰』出了問題。猜測可能是 YUM 更新後，對『認證金鑰』的處理不同所致。只好重新再執行一次前文『在 Fedora 快速安裝 Chrome 的方法』的步驟，

由上面的訊息可以看到，Google Chrome 成功更新到最新版。
