当我尝试使用apt或安装新包时apt-get，我收到以下错误消息：
$ sudo apt install sl
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
因此，我遵循以下说明：
$ dpkg --configure -a
dpkg: error: requested operation requires superuser privilege
$ sudo dpkg --configure -a
Setting up icaclient (13.10.0.20) ...
这花了很长时间，所以过了一段时间后我按下 ctrl+c，结果是这样的：
^Cdpkg: error processing package icaclient (--configure):
installed icaclient package post-installation script subprocess was interrupted
Errors were encountered while processing:
icaclient
所以现在当我再次尝试安装一个包时，它看起来有效了：
$ sudo apt install sl
Reading package lists... Done

sl is already the newest version (3.03-17build2).
The following packages were automatically installed and are no longer required:
libllvm7 linux-headers-4.15.0-50 linux-image-4.15.0-50-generic linux-modules-4.15.0-50-generic
Use 'sudo apt autoremove' to remove them.

Do you want to continue? [Y/n]
按 Y 键后：
Setting up icaclient (13.10.0.20) ...
Progress: [ 0%]

现在它又卡住了，我无法通过 ctrl+c 退出。当我关闭终端屏幕时，它会从帖子的开头重复。
我该如何解决这个问题？
nb 我每天都使用 icaclient 应用程序，但我可能会再次安装它。
答案1
它挂在安装后脚本上，如上面的一条错误消息所述。经过一番搜索，我发现安装后脚本存储在/var/lib/dpkg/info/
所以我可以使用以下方法轻松修复它：
sudo rm /var/lib/dpkg/info/icaclient.postinst
之后我必须运行sudo dpkg --configure -a并删除一些锁文件。
现在 apt 可以正常工作了！
