“sudo apt autoremove”指令不起作用（“/var/cache/debconf/config.dat 被另一個程序鎖定”）

tag-icon • tag-icon apt sudo package-management lock
“sudo apt autoremove”指令不起作用（“/var/cache/debconf/config.dat 被另一個程序鎖定”）

我嘗試過諸如編輯panasoniclpd.init文件之類的解決方案，但它也不起作用。每當我嘗試從 CLI 更新或安裝時，都會顯示此問題

sudo apt autoremove

如果無法重新啟動並且您可以存取計算機，請嘗試以下操作：

1）從錯誤訊息中找到鎖定檔案的進程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）透過以下方式檢查流程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）殺死進程。

$ sudo kill -9 44515

4)apt再次嘗試您的命令。
