解决 apt-get 提示警告信息 N: Skipping acquire of configured file 'nginx/binary-i386/Packages' as repository

执行 apt-get update 报错：

N: Skipping acquire of configured file 'nginx/binary-i386/Packages' as repository 'http://nginx.org/packages/ubuntu bionic InRelease' doesn't support architecture 'i386'

解决方法

编辑文件 /etc/apt/sources.list.d/nginx.list。

原来的

deb http://nginx.org/packages/ubuntu/ bionic nginx
deb-src http://nginx.org/packages/ubuntu/ bionic nginx

改为

deb [arch=amd64] http://nginx.org/packages/ubuntu/ bionic nginx
deb-src http://nginx.org/packages/ubuntu/ bionic nginx

增加 [arch=amd64] 后，重新执行 apt-get update 命令，这次警告消息没有了。
