Oracle Linux yum 更新後不工作

我已將我的 Oracle Linux 6.4 伺服器更新為已註冊到 spacewalk 伺服器的 Oracle Linux 6.8。但更新後，yum 命令在伺服器中不起作用。

[root@j4server tmp]# yum update
Loaded plugins: aliases, changelog, kabi, presto, refresh-packagekit, rhnplugin, security, tmprepo, verify,
             : versionlock
Traceback (most recent call last):

   errcode = main(args)

   login_info = up2dateAuth.getLoginInfo()

   login()

   if readCachedLogin():

   expireTime = float(li['X-RHN-Auth-Expiration'])
KeyError: 'X-RHN-Auth-Expiration'

它正在拋出這個輸出。當我嘗試禁用 rhn-plugin 時，yum 命令有效，列出了 spacewalk 上的軟體包，但正如您猜測的那樣無法安裝它們。

您對這種情況有什麼想法嗎？謝謝你的幫助！

我找到了解決方案，我在這裡發布解決方案，以防有人遇到同樣的情況。出現此故障的原因是，當您通過 spacewalk 使用“yum update”命令更新 Oracle Linux 伺服器時，yum update 會將伺服器 spacewalk-enabled rhn 外掛替換為啟用 ULN 的外掛。

在將“RHEL 6.8” ISO 安裝到 Oracle Linux 伺服器之後，我已經用“yum erase up2date”和“yum erase pirut”刪除了 up2date 包。在我將此iso添加為本地倉庫之後。我已經使用“yum install rhn-client-tools rhn-check rhn-setup rhnsd m2crypto yum-rhn-plugin”安裝了 rhn 工具並刪除了本地 repo 文件。現在一切正常！
