我是 Ubuntu 新手，如果这是一个快速修复，请原谅。我在运行时遇到问题apt-get update，反复出现的错误消息是：
Ign http://archive.ubuntu.com trusty InRelease

W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty/Release Unable to find expected entry 'restricted/binary-i3836/Packages' in Release file (Wrong sources.list entry or malformed file)
E: Some index files failed to download. They have been ignored, or old ones used instead.
我尝试删除 sources.list 文件，然后使用命令“software-properties-gtk”替换它，但不起作用。有什么想法吗？

似乎我之前使用“dpkg --add-architecture”命令时不小心将错误的外部架构添加到我的计算机中。下面是不正确我输入的命令：
sudo dpkg --add-architecture i3836
这就是 binary-i3836 反复出现的问题的原因。我使用以下命令来修复该问题：
sudo dpkg --remove-architecture i3836
我现在可以使用 sudo apt-get update 了。
