我正在运行 Debian 9（延伸）amd64。我尝试运行一个依赖 libc6-dev-i386 工作的程序，但无法使用以下命令安装该软件包：
apt-get install libc6-dev-i386
我收到这个错误
The following packages have unmet dependencies:
libc6-dev-i386 : Depends: libc6-i386 (= 2.24-11+deb9u3) but it is not going to be installed
Depends: libc6-dev (= 2.24-11+deb9u3) but 2.27-6 is to be installed
Recommends: gcc-multilib but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
我尝试将 libc6-i386_2.27-6 版本降级到 2.24-11+deb9u3：
dpkg -i --force-downgrade libc6-i386_2.24-11+deb9u3_amd64.deb.
但我得到了这个：
