昨天我在 14.04 bleachbit 上运行了除内存之外的几乎所有选项（现在我明白这不是使用 bleachbit 最正确的方法），最后当我通过命令行中断时程序结束了。
现在，当我打开软件更新程序时，它会加载软件列表，但随后警告我“无法下载存储库信息，请检查您的互联网连接”，然而，在我单击设置并再次关闭而没有执行任何操作后，更新程序实际上可以正常继续，要么告诉我所有内容都是最新的，要么下载/安装更新。
同时，我还定期收到错误通知，告诉我“更新信息已过时”，我需要单击显示更新，然后返回软件更新程序。
我相信系统还没有受到太多其他“损害”，只是我还没有发现而已（例如 find 也变得很慢，虽然我猜是因为缓存文件消失了）。我能做些什么来将损害降到最低？
提前致谢！
sudo apt-get update 的输出是：（我将 http 和 https 替换为 ' ' 和 ' s '）

答案1
您在输出中看到的问题是 Google Chrome 不再适用于 32 位架构。因此他们从服务器中删除了存储库，您无法再从那里更新列表。
为了解决该问题，只需从配置中删除列表条目，方法是删除它们所在的文件：
sudo rm /etc/apt/sources.list.d/google-chrome*
然后摆脱过时的 Google Chrome 浏览器并安装类似的开源浏览器 Chromium。
答案2
我看不出 BleachBit 真的损坏了您的系统。它执行的操作通常是安全的——除非您需要缓存、临时文件等。如果没有更好的信息，似乎与错误消息的关联只是巧合。
您的下一步是排除更新程序故障，因此我建议在终端中运行sudo apt-get update并阅读消息。错误是针对一个源还是所有源？您有自定义/第三方源吗？也许其中一个源的镜像已关闭。
还要检查您的磁盘分区是否已满。
最后，确保下载最新的BleachBit 清洁剂因为 Ubuntu 存储库通常有古老的版本。
