系统更新的时候报错：
Skipping acquire of configured file 'main/binary-i386/Packages' as repository
'http://repo.mongodb.org/apt/debian stretch/mongodb-org/4.0 InRelease' doesn't support architecture 'i386'
acquire of configured file 'main/binary-i386/Packages' as repository 'http://repo.mongodb.org/apt/debian
stretch/mongodb-org/4.0 InRelease' doesn't support architecture 'i386'
解决方法 ：
vim /etc/apt/sources.list.d/mongodb-org-4.0.list
在deb后面加入 [arch=amd64]
如果是其他软件更新
