相同的包安裝在兩個架構版本中

我在新安裝的 debian 8.7 上使用 i386/amd64 多架構。我剛剛添加它dpkg --add-architecture i386以安裝我在 amd64 版本中找不到的包。

然後我使用儲存庫安裝了我的 nvidia 驅動程序的 jessie-backports (375) 版本：

# jessie-backports
deb http://httpredir.debian.org/debian jessie-backports main contrib non-free

這就是突觸現在給我的：

我將所有這些 nvidia 軟體包安裝了兩次，每個架構一個。這有什麼正常的嗎？在這一切過程中我做錯了什麼嗎？

真正奇怪的是，apt list --installed |grep nvidia它甚至沒有給我相同的答案：

ut@Albizia:~$ apt list --installed |grep nvidia

據此，每個軟體包只安裝一次。我不知道該相信誰了。

Synaptic 是對的，您為amd64和i386. 這是正常的：NVIDIA 驅動程序包依賴於nvidia-driver-libs，它本身會建議在庫nvidia-driver-libs-i386中拉取哪個（如果您有可用的體系結構）。這樣，二進製文件都可以使用庫；例如，如果您想執行 32 位遊戲，這會派上用場。i386``amd64``i386``amd64``i386

apt list每個安裝的包只顯示一個架構，所以你只會看到amd64安裝了這兩種架構的包的版本。
