我在新安装的 debian 8.7 上使用 i386/amd64 多架构。我只是添加它来dpkg --add-architecture i386安装在 amd64 版本中找不到的软件包。
然后我使用存储库安装了我的 nvidia 驱动程序的 jessie-backports (375) 版本：
# jessie-backports
deb http://httpredir.debian.org/debian jessie-backports main contrib non-free
这就是突触现在给我的：
我把所有这些 nvidia 软件包都安装了两次，每个架构一个。这正常吗？我在整个过程中做错了什么吗？
真正奇怪的是，它apt list --installed |grep nvidia甚至没有给我相同的答案：
ut@Albizia:~$ apt list --installed |grep nvidia

据此，每个包仅安装一次。我不知道该相信谁了。
答案1
Synaptic 是对的，您已经为amd64和i386.这是正常的：NVIDIA 驱动程序包依赖于nvidia-driver-libs，它本身会建议nvidia-driver-libs-i386引入i386库amd64（如果您有i386可用的架构）。这样，amd64二进制i386文件就可以使用这些库；例如，如果您想运行 32 位游戏，这会派上用场。
apt list每个已安装的软件包仅显示一种架构，因此您只能看到amd64安装了两种架构的软件包的版本。
