我剛剛在虛擬機器上安裝了最新的 Debian 版本（8.4），一切都很順利。
然後我從 Debian 儲存庫安裝了 nginx 伺服器，得到的版本是 1.6.2，而最新的可用版本是 1.10，所以我想更新它。
我嘗試這樣做的方式可能是錯誤的，但這是我迄今為止所發現的。
sources.list我首先透過以下方式將 nginx 儲存庫新增至檔案來更新我的儲存庫：
sudo sh -c "echo 'deb http://nginx.org/packages/debian/ `lsb_release -cs` nginx' >> /etc/apt/sources.list"
sudo sh -c "echo 'deb-src http://nginx.org/packages/debian/ `lsb_release -cs` nginx' >> /etc/apt/sources.list"
curl http://nginx.org/keys/nginx_signing.key | apt-key add -
sudo apt-get update
然後，我嘗試使用以下命令安裝最新的 nginx 版本：
sudo apt-get install nginx
我得到這個問題：
root@Debian:/#LANG=C apt-get install nginx

我該如何解決這個問題？
答案1
基本錯誤是這樣的（強調我的）：
dpkg：處理檔案 /var/cache/apt/archives/nginx_1.10.0-1~jessie_i386.deb 時發生錯誤（--unpack）：試著覆寫'/etc/default/nginx'，它也在套件 nginx-common 1.6.2-5+deb8u1 中
這意味著您正在安裝的新軟體包正在嘗試覆蓋另一個軟體包（您安裝的nginx-common）提供的文件，並dpkg擔心會破壞內容並拒絕這樣做。
簡單的解決方案是完全刪除nginx-common軟體包，然後再次安裝新版本：
sudo apt-get purge nginx-common
sudo apt-get install nginx
