deb包升級時如何調試dpkg錯誤碼（1）？

Operating System: Debian GNU/Linux 8.8 (jessie)
Kernel: Linux 3.16.0-4-amd64
Architecture: x86-64

我有幾個 Debian 伺服器。

每個都包含在預設儲存庫nginx版本 1.6 中。

從原始nginx儲存庫更新後，在所有伺服器上收到相同的錯誤：

Preparing to unpack .../nginx_1.12.0-1~jessie_amd64.deb ...
Unpacking nginx (1.12.0-1~jessie) over (1.6.2-5+deb8u4) ...
dpkg: error processing archive /var/cache/apt/archives/nginx_1.12.0-1~jessie_amd64.deb (--unpack):
 trying to overwrite '/etc/default/nginx', which is also in package nginx-common 1.6.2-5+deb8u4
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
Errors were encountered while processing:
 /var/cache/apt/archives/nginx_1.12.0-1~jessie_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

我試圖deb從原始碼建構包，但仍然得到同樣的錯誤。

如果不將 Debian 重新安裝到更新版本，我找不到任何升級它的方法。

/var/log/dpkg.log:

2017-06-26 19:56:31 startup archives install
2017-06-26 19:56:31 upgrade nginx:all 1.6.2-5+deb8u4 1.12.0-1~jessie
2017-06-26 19:56:31 status half-configured nginx:all 1.6.2-5+deb8u4
2017-06-26 19:56:31 status unpacked nginx:all 1.6.2-5+deb8u4
2017-06-26 19:56:31 status half-installed nginx:all 1.6.2-5+deb8u4
2017-06-26 19:56:32 status unpacked nginx:all 1.6.2-5+deb8u4
2017-06-26 19:56:32 status installed nginx:all 1.6.2-5+deb8u4

我已嘗試完全解除安裝/清除預設設置nginx並安裝更新版本，但仍然出現錯誤。

The following packages have been kept back:
libpcre3 libpcre3-dev nginx nginx-common nginx-full
0 upgraded, 0 newly installed, 0 to remove and 5 not upgraded.

成為根：

sudo -i

或者：

su

---

2017-06-26 19:56:31 status half-configured nginx:all 1.6.2-5+deb8u4

配置包：

dpkg --configure -a

---

修復損壞的包：

apt-get install --fix-broken

---

繼續升級：

apt-get dist-upgrade

清除+重新安裝時很難說出您嘗試了什麼，但試試這個：

sudo dpkg --purge --force-all nginx nginx-common nginx-full
sudo apt-get install nginx
