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

我尝试过诸如编辑panasoniclpd.init文件之类的解决方案，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

如果无法重新启动并且您可以访问计算机，请尝试以下操作：

1）从错误信息中找到锁定文件的进程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）通过以下方式检查流程ps：

$ 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）杀死进程。

$ sudo kill -9 44515

4)apt再次尝试您的命令。
