"sudo apt自动删除“命令不起作用("/var/cache/debconf/config.dat被另一个进程锁定”)

Question

我尝试过像在panasoniclpd.init文件上进行编辑这样的解决方案，但它也不起作用。每当我尝试从CLI更新或安装时，都会显示此问题。

sudo apt autoremove

如果重新启动不是一个选项，并且您可以访问该机器，请尝试以下操作：

1)查找从错误消息锁定文件的进程ID：

$ sudo lsof /var/cache/debconf/config.dat
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
frontend 44515 root 4uW REG 252,0 60012 55592027 /var/cache/debconf/config.dat

2)通过ps检查流程：

$ sudo ps auxf | grep 44515
root 44515 0.0 0.0 60700 2196 pts/0 S+ Feb18 0:00 | _ /usr/bin/perl -w 
/usr/share/debconf/frontend /var/lib/dpkg/info/postfix.postinst configure 3.1.0-3ubuntu0.2

3)扼杀过程。

$ sudo kill -9 44515

4)再次尝试apt命令。
