我的应用程序有一个 deb 包。有时当我使用命令安装或删除某些软件（例如 synaptic 或 openssh-server）时
sudo apt-get install (or remove) synaptic
它使用参数“configure 1.1.123.0”为我的程序执行 postinst 脚本，其中 1.1.123.0 是我安装的应用程序的版本。
为什么会出现这种情况？我的程序与 synaptic、openssh-server 和其他软件无关。我该如何调试导致这种情况的原因？
以下是终端的输出：
user@ubuntu:~/tmp$ sudo apt-get remove synaptic

答案1
请发布输出
sudo dpkg --configure -a
如果你收到如下错误Errors were encountered while processing: myapp:i386
然后使用以下方法删除我的应用程序：
sudo apt-get purge myapp
并且还对re-install所有损坏的下载使用以下内容。
sudo apt-get install -f
损坏软件包的问题仍然存在，解决方案是手动编辑 dpkg 状态文件。
sudo gedit /var/lib/dpkg/status
（你可以用vim代替gedit）
找到损坏的包，删除有关它的整个信息块并保存文件。
