更新信息已过时

我该如何解决更新问题？我使用的是 Maverick 10.10 并每天更新，但我收到警告三角形，提示我更新信息已过时。执行更新后，它提示我上次更新时间是 26 天前。

查看其中的来源列表后/etc/apt/sources.list显示以下内容：

# deb cdrom:[Ubuntu 10.10 _Maverick Meerkat_ - Release i386 (20101007)]/ maverick main restricted

答案1

当您的一个或多个源无法更新时，您会看到此类消息。有时这是因为您的系统无法访问其中一个站点来下载存储库信息（这通常是因为相关站点发生故障、站点路径上某处的互联网链接出现问题或 DNS 出现问题）。这里看起来您无法确认站点的身份，因此 Ubuntu 认为使用此源不安全。

根据您的更新输出，您需要获取 tuxfamily.org 的正确身份密钥，或者将其从您的源中注释掉。
