• 解决办法两种办法

1. 删除apt的进程

# ps -ef | grep apt
root       3334      1  0 23:19 ?        00:00:00 /bin/sh /usr/lib/apt/apt.systemd.daily install
root       3348   3334  0 23:19 ?        00:00:00 /bin/sh /usr/lib/apt/apt.systemd.daily lock_is_held install
_apt       3431   3380  0 23:20 ?        00:00:00 /usr/lib/apt/methods/http
root       3435   3059  0 23:20 pts/8    00:00:00 grep --color=auto apt
# kill -9 3334 3348 3431
# ps -ef | grep apt
root       3440   3059  0 23:21 pts/8    00:00:00 grep --color=auto apt

2. 删除解锁文件

# rm /var/cache/apt/archives/lock 
# rm /var/lib/dpkg/lock
