Answer 1

您尝试连接的域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打开它。

2. 在软件和更新窗口中选择 Ubuntu 软件选项卡 ->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，并在此窗口中单击“选择最佳服务器”按钮。

4. 等待“选择最佳服务器”完成并单击“选择服务器”按钮。选择的最佳服务器可能是您所在国家或地区附近的服务器。

5. 在“身份验证”窗口中，使用您的用户密码进行身份验证。

6. 您将看到一个带有消息的窗口，显示The information about available software is out-of-date。单击重新加载按钮以更新可用的软件缓存。
