我在64位计算机上的Ubuntu 12.04 LTS上遇到以下问题：每当我尝试更新aptitude存储库时，更新都会奇怪地失败，并显示i386相关错误。我认为这不应该在64位系统上发生。
root@liv-HP-Compaq-dc7900:/home/liv# apt-get update
Ign file: apt-build Release.gpg
Get:1 file: apt-build Release [107 B]
Ign file: apt-build/main TranslationIndex
Err file: apt-build/main i386 Packages
File not found
[..]
W: Failed to fetch file:/var/cache/apt-build/repository/dists/apt-build/main/binary-i386/Packages File not found
E: Some index files failed to download. They have been ignored, or old ones used instead.
我尝试恢复status-old时没有运气：
sudo cp /var/lib/dpkg/status-old /var/lib/dpkg/status
我也尝试过：
root@liv-HP-Compaq-dc7900:/home/liv# apt-get -f install

但这似乎并没有做或报告任何有用的东西。随后的每一个都apt-get update以错误结束。
作为记录，我的/etc/apt/sources.list文件如下所示：

有什么问题，我该如何解决？
从谷歌的修复是在它的途中（错误这里）

@törzsmókus这个问题与Google无关，并且比链接的问题早了大约两年。如果有的话，您链接到的问题与当前问题重复。

好吧，我接受你的推理。我只想指出，解决这两个问题的方法基本相同。

@törzsmókus这就是IMO为什么要将另一个问题标记为与此问题重复的原因，因为这个问题更笼统。
