我有以下問題。我有 2 個測試伺服器，我想將其中一個配置為 maas 伺服器，另一個配置為節點。我下載了最新的12.10並在安裝過程中使用了maas選項。重新啟動後，apache2 正在運行，但開啟 maas 會導致以下結果：
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
機器是舊的HP DL180 G3，在12.04.2 LTS下運作順利！ var/log/apache2/error.log 中出現以下錯誤

我不知道這裡發生了什麼事。有什麼建議麼？
答案1
看起來 avahi 服務有問題，您可以嘗試執行： $ sudo service avahi-daemon restart 看看這是否可以解決問題？
