如果 dpkg 删除脚本失败，如何强制删除包？

Question

我正在尝试删除我删除/etc/init.d/disco-master文件的包（试图手动删除包）。我想删除disco-master包裹。我现在该怎么做？

当我这样做时会发生这种情况sudo apt-get remove disco-master：

removing disco-master ...
invoke-rc.d: unknown initscript, /etc/init.d/disco-master not found.
dpkg: error processing disco-master (--remove):
 subprocess installed pre-removal script returned error exit status 100
Errors were encountered while processing:
 disco-master
E: Sub-process /usr/bin/dpkg returned an error code (1)

当我这样做时，sudo apt-get install --reinstall disco-master我得到以下信息：

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 disco-master : Depends: disco-node (= 0.4.2+nmu1) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

当我这样做时sudo apt-get -f install：

Unpacking disco-node (from .../disco-node_0.4.2+nmu1_amd64.deb) ...
dpkg: error processing /var/cache/apt/archives/disco-node_0.4.2+nmu1_amd64.deb (--unpack):

E: Sub-process /usr/bin/dpkg returned an error code (1)

当我运行时，sudo apt-get remove disco-node我得到以下信息：

Package disco-node is not installed, so not removed
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 disco-master : Depends: disco-node (= 0.4.1) but it is not going to be installed
                Depends: python-disco (= 0.4.1) but 0.4.2+nmu1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

当我这样做时，sudo dpkg -P --force-all disco-master我得到了：

Removing disco-master ...
invoke-rc.d: unknown initscript, /etc/init.d/disco-master not found.
dpkg: error processing disco-master (--purge):
 subprocess installed pre-removal script returned error exit status 100
Errors were encountered while processing:

Answer 1

创建一个虚拟的 initscript 来欺骗 dpkg：

sudo nano /etc/init.d/disco-master

输入以下内容：

#!/bin/bash
exit 0

保存文件，设置执行权限 ( sudo chmod 755 /etc/init.d/disco-master) 并重试sudo apt-get remove disco-master。
