异种i386源

Question

我有一个正常的消息来源清单：

$ cat /etc/apt/sources.list
deb http://ports.ubuntu.com/ xenial main restricted universe multiverse
deb-src http://ports.ubuntu.com/ xenial main restricted universe multiverse

deb http://ports.ubuntu.com/ xenial-updates main restricted universe multiverse
deb-src http://ports.ubuntu.com/ xenial-updates main restricted universe multiverse

deb http://ports.ubuntu.com/ xenial-security main restricted universe multiverse
deb-src http://ports.ubuntu.com/ xenial-security main restricted universe multiverse

deb http://ports.ubuntu.com/ xenial-backports main restricted universe multiverse
deb-src http://ports.ubuntu.com/ xenial-backports main restricted universe multiverse

但是，当我进行适当的更新时，我会发现这些错误：

W: The repository 'http://ppa.launchpad.net/kernel-ppa/ppa/ubuntu xenial Release' does not have a Release file.
E: Failed to fetch http://ppa.launchpad.net/kernel-ppa/ppa/ubuntu/dists/xenial/main/binary-armhf/Packages  404  Not Found
E: Failed to fetch http://ports.ubuntu.com/dists/xenial/main/binary-i386/Packages  404  Not Found [IP: 91.189.88.150 80]

E: Some index files failed to download. They have been ignored, or old ones used instead.

这些错误是有意义的，因为它们不在实际的目录中：http://ports.ubuntu.com/dists/xenial-backports/main/，但是我怎么才能得到i386包呢？如果我使用安装脚本作为依赖项，但它失败了，这是否意味着脚本需要更新其包才能在其末尾使用:i386？

这是我的来源列表中需要改变的东西，还是我使用的是一面坏镜子？我如何从CLI中解决这个问题？

仍然不知道其他问题的答案，但我能够用以下方法解决源错误：

sudo dpkg --remove-architecture i386
