当我检查更新时，出现“无法下载存储库信息”错误。
这是详细信息下的内容：
W: Failed to fetch gzip:/var/lib/apt/lists/partial/us.archive.ubuntu.com_ubuntu_dists_natty_main_source_Sources Hash Sum mismatch,
E: Some index files failed to download. They have been ignored, or old ones used instead.
我刚刚安装了 16.04 LTS。但是，我无法更新。
$ sudo apt-get update
Fetched 34,3 MB in 1h 51min 52s (5.110 B/s)
Reading package lists... Done

我尝试了很多东西，但没有帮助。由于“哈希和不匹配”错误，我尝试了Trouble download packages list 中的解决方案，但它没有解决问题。
当我运行时，sudo apt-get update我收到四个哈希和不匹配错误：
W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/trusty-updates/main/binary-amd64/Packages Hash Sum mismatch
W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/trusty-updates/universe/binary-amd64/Packages Hash Sum mismatch

W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/trusty-updates/universe/binary-i386/Packages Hash Sum mismatch
我试着用
sudo rm /var/lib/apt/lists/* -vf
sudo apt-get update
但这没有用，也没有用
sudo apt-get clean
sudo apt-get update
或者
sudo apt-get dist-upgrade
sudo apt-get update
我还有其他方法可以尝试解决这个问题吗？
在我执行了其中一个sudo apt-get install eclipse eclipse-cdt g++程序后，我发现 Ubuntu 计划下载超过 400Mb，这将需要 2 个多小时。它太长了。我还发现它是从美国下载的：
Get:21 http://us.archive.ubuntu.com/ubuntu/ trusty-updates/main libservlet3.0-java
all 7.0.52-1ubuntu0.3 [294 kB]
我在欧洲，也许我应该告诉 Ubuntu 从更近的源下载。我该怎么做？
每当我单击软件更新程序时，它都会显示无法下载存储库信息。
这几天一直在说这个，我不知道为什么，我的互联网连接很好，我可以手动下载软件。
有时当我单击“确定”时它会崩溃，然后尝试再次查找更新并给我相同的消息。
有任何想法吗？
[编辑] 我刚刚尝试了一个答案，在那里我重置了下载的来源，但我收到了这条消息：
