$ ps aux | grep apt root 1747 0.0 0.0 4628 808 ? Ss 07:06 0:00 /bin/sh /usr/lib/apt/apt.systemd.daily update root 1769 0.0 0.0 4628 1820 ?

停掉进程

1	$ sudo killall apt apt-get

这是比较快捷的方式，但是还不够，前两条都无法关闭，只能将 pid 杀死

1	$ sudo kill -9

删除加锁文件

1 2 3

$ sudo rm /var/lib/apt/lists/lock $ sudo rm /var/cache/apt/archives/lock $ sudo rm /var/lib/dpkg/lock*

重新配置 dpkg

1 2 3

$ sudo dpkg --configure -a dpkg: error: parsing file '/var/lib/dpkg/updates/0004' near line 0: newline in field name '#padding'

这时候有可能还会出现一个错误，这时要手动删除该文件

1	$ sudo rm -rf /var/lib/dpkg/updates/0004

再次执行配置命令，然后继续安装软件即可

1 2	$ sudo apt update -y $ sudo apt install -y redis
