我中断了安装，现在 apt 和 apt-get 无法使用任何参数。我总是得到相同的错误：
E: dpkg execution was interrupted, you must manually run "sudo dpkg --configure -a" to correct the problem.
编辑：我尝试过sudo dpkg --configure -a，但只成功了

编辑2：我已经尝试过sudo apt install --reinstall cento，这是出口：

编辑3：我已经做了udo fuser -v /var/cache/debconf/config.dat
USUARIO ORDEN DE ACCESO PID
/var/cache/debconf/config.dat:
root 2845 F.... frontend
然后我做了sudo kill 2845（我没有得到答案）
然后我做了sudo kill -9 2845
kill: (2845): No such process
然后我尝试sudo apt autoremove：

然后它就停在那里，不再做任何事

关于此锁定问题的解决方案详见维基百科：
sudo fuser -v /var/cache/debconf/config.dat
将显示哪个进程正在持有锁：
USER PID ACCESS COMMAND
/var/cache/debconf/config.dat:
root 18210 F.... dpkg-preconfigu
然后你只需要记下 PID 并像这样终止它：
sudo kill PID
sudo kill -9 PID # if the first doesn't work
