已安装的子进程预删除脚本返回错误退出状态5

Question

试图卸载clamav和clamav-daemon，但似乎apt和dpkg被卡住了，如果没有这个错误，什么事情都无法完成：

dpkg --remove输出：

(Reading database ... 385080 files and directories currently installed.)
Removing clamav-daemon (0.99.2+dfsg-0ubuntu0.16.04.2) ...
Failed to stop clamav-daemon.socket: Unit clamav-daemon.socket not loaded.
dpkg: error processing package clamav-daemon (--remove):
 subprocess installed pre-removal script returned error exit status 5
/usr/bin/deb-systemd-helper: error: unable to read clamav-daemon.service
/usr/bin/deb-systemd-helper: error: unable to read clamav-daemon.socket
Errors were encountered while processing:
 clamav-daemon

任何类型的apt命令都会将以下内容添加到末尾：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 clamav-daemon : Depends: clamav-base (= 0.99.2+dfsg-0ubuntu0.16.04.2) but 0.99.3+addedllvm-0ubuntu0.16.04.1 is installed
                 Recommends: clamdscan but it is not installed
E: Unmet dependencies. Try using -f.

我试过apt -f install，尝试dpkg --configure -a，尝试安装，然后删除，尝试制作名为clamav-daemon.service/socket的假文件，希望脚本能够接受它并继续。什么都帮不上忙，我也没办法了。

任何帮助都是非常感谢的。

在下面的路径中可以找到预删除脚本。

/var/lib/dpkg/info/clamav-daemon.prerm

您应该能够编辑此脚本以删除正在失败的部分。或者，您可以完全删除脚本，但这可能跳过其他清理步骤。
