Answer 1

您尝试连接的域名http://na.archive.ubuntu.com已过期。 在“软件和更新”中选择一个新的下载服务器。

1. 在Dash中搜索软件和更新并将其打开。

2. 在“ 软件和更新”窗口中，选择“Ubuntu软件”选项卡 – > 从下载后：单击黑色三角形以显示下拉菜单 – >从下拉菜单中单击“ 其他” 。

3. 将打开一个新的“选择下载服务器”窗口，然后在此窗口中单击“ 选择最佳服务器”按钮。

4. 等待Select Best Server完成，然后单击Choose Server按钮。 选择的最佳服务器可能是您所在国家/地区内或附近的服务器。

5. 在“ 身份validation”窗口中，使用您的用户密码进行身份validation。

6. 您将看到一个窗口，其中显示一条消息，指出有关可用软件的信息已过时 。 单击“ 重新加载”按钮以更新可用的软件高速缓存。
