Wireguard安装错误:无法更正问题，您持有损坏的软件包。但是，不保存任何包。

Question

在Debian 10机器上，Wireguard安装失败，错误描述如下。

The following packages have unmet dependencies:
 wireguard : Depends: wireguard-dkms (>= 0.0.20191219) but it is not installable or
                      wireguard-modules (>= 0.0.20191219) but it is not installable
E: Unable to correct problems, you have held broken packages.

但是，以下命令(以root用户身份运行)不返回任何输出，表明没有保存任何包。

dpkg --get-selections | grep hold 

任何帮助都是非常感谢的，因为我过去没有遇到过这个错误。

使用了以下进程，所有命令都以root用户身份运行：

echo "deb http://deb.debian.org/debian/ unstable main" > /etc/apt/sources.list.d/unstable.list
printf 'Package: *\nPin: release a=unstable\nPin-Priority: 90\n' > /etc/apt/preferences.d/limit-unstable

这个问题已经通过以下教程编译模块得到了解决：https://www.wireguard.com/compilation/

我不必像正常安装时那样编译这些工具。

apt-get install libmnl-dev libelf-dev linux-headers-$(uname -r) build-essential pkg-config

git clone https://git.zx2c4.com/wireguard-linux-compat
git clone https://git.zx2c4.com/wireguard-tools

make -C wireguard-linux-compat/src -j$(nproc)
sudo make -C wireguard-linux-compat/src install
