xenial i386来源
我有一个正常的来源列表：
$ 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 但是在更新时我遇到了这些错误：
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: Failed to fetch http://ports.ubuntu.com/dists/xenial-updates/main/binary-i386/Packages 404 Not Found [IP: 91.189.88.150 80] E: Failed to fetch http://ports.ubuntu.com/dists/xenial-security/main/binary-i386/Packages 404 Not Found [IP: 91.189.88.150 80] E: Failed to fetch http://ports.ubuntu.com/dists/xenial-backports/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.
这些错误是有道理的，因为它们不在实际目录中： http ： //ports.ubuntu.com/dists/xenial-backports/main/但我还应该如何获得i386软件包呢？ 如果我使用安装脚本作为依赖项并且它失败了，是否意味着脚本需要更新其包使用:i386在它的末尾？
这是在我的源列表中更改的内容还是我使用的是坏镜像？ 如何从CLI修复此问题？
仍然不知道其他问题的答案，但我能够解决源错误：
sudo dpkg --remove-architecture i386
