添加 xenial-updates 行

这是一个后续问题交叉编译 armhf 并安装静态库

在接受的答案中最后提到了以下内容，

说明：多架构软件包需要在所有架构上安装相同的版本。因此，您应该拥有版本 229-4ubuntu21.4 的 libudev-dev:armhf，但您当前的存储库配置不包含此版本。因此，您应该在支持此版本的位置添加 xenial-updates 行。

我想知道我究竟该如何做？

因此，您应该在支持此版本的位置添加 xenial-updates 行。

我对此很陌生，因此带有示例的详细答案将会很有帮助。

使用下面显示的 sources.list，我尝试了“apt-cache policy libudev-dev:{amd64,armhf}”，其输出如下所示。“sudo apt install libudev-dev:armhf”的错误如下。

在 sources.list 中尝试以下操作

deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ xenial main multiverse restricted universe
deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ xenial main multiverse restricted universe
deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ xenial-updates main multiverse restricted universe
deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ xenial-updates main multiverse restricted universe
deb [arch=amd64] http://security.ubuntu.com/ubuntu/ xenial-security main multiverse restricted universe

使用 sudo apt install libudev-dev:armhf 仍然会出现以下错误

该问题中的 OP 对其进行了编辑，包括以下内容：

apt-cache policy libudev-dev:{amd64,armhf}输出以下内容：

libudev-dev:
  Installed: (none)
  Candidate: 229-4ubuntu21.4
  Version table:
     229-4ubuntu21.4 500
        500 http://archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages
     229-4ubuntu21.1 500
        500 http://security.ubuntu.com/ubuntu xenial-security/main amd64 Packages
     229-4ubuntu4 500
        500 http://archive.ubuntu.com/ubuntu xenial/main amd64 Packages
libudev-dev:armhf:
  Installed: (none)
  Candidate: 229-4ubuntu4
  Version table:
     229-4ubuntu4 500
        500 http://ports.ubuntu.com/ubuntu-ports xenial/main armhf Packages

请注意，两种架构的“候选”版本是不同的，因为xenial-updates和xenial-security存储库有的较新版本amd64，但没有的较新版本armhf。

@psiphi75 说您应该为两种架构安装完全相同的版本，因此包含xenial-updates会导致不匹配（尽管如此xenial-security）。因此他们的建议是不将其包含在内sources.list（修改其答案中的步骤 4），然后libudev-dev为两种架构安装。

然而， 根据软件包索引，libudev-dev现在有适用于以下体系结构的以下版本xenial-updates：

229-4ubuntu21.29: amd64 arm64 armhf i386 powerpc ppc64el s390x

amd64因此，由于现在和armhf中均有相同的版本xenial-updates，因此您可以将其包含在 中sources.list。
