你能告訴'/ etc/hosts'的內容？ – Salem

＃＃hosts該文件描述了TCP/IP子系統的一些主機名到地址＃映射。在啓動時使用的主要是＃，當沒有名稱服務器正在運行時。＃在小型系統上，可以使用該文件而不是＃「named」名稱服務器。＃語法：＃＃IP地址完全合格的主機名短主機名＃ 127.0.0.1本地主機＃特殊的IPv6地址 :: 1本地主機IPv6的本地主機IPv6的環回 FE00 :: 0 ipv6-localnet ff00 :: 0 ipv6-mcastprefix –

我給出了圖像和內容 –

嘗試在/etc/hosts（你需要根/ sudo訪問）從

127.0.0.1 localhost

localhost項目更改爲

127.0.0.1 localhost linux-78et.suse
