系统升级到18.04后执行apt-get install的时候报错

root@zhf-maple:/home/zhf/桌面# apt-get install vim-scipts
E: 无法获得锁 /var/lib/dpkg/lock-frontend - open (11: 资源暂时不可用)
E: 无法获取 dpkg 前端锁 (/var/lib/dpkg/lock-frontend)，是否有其他进程正占用它？

这是因为升级后某些软件包还在占用apt资源，通过ps -aux | grep apt 查看哪些在占用apt进程，下面红色标红的这些都是在占用apt的进程

执行kill命令杀掉这些进程

kill -9 5394

kill -9 5405

kill -9 11471

kill -9 11564

kill -9 11566

然后执行：

rm /var/cache/apt/archives/lock

p { margin-bottom: 0.25cm; direction: ltr; line-height: 115%; text-align: justify; }p.western { font-family: "Times New Roman", serif; font-size: 10pt; }p.cjk { font-family: "宋体"; font-size: 10pt; }p.ctl { font-family: "Times New Roman"; font-size: 12pt; }a:link { color: rgb(0, 0, 255); }

rm /var/lib/dpkg/lock

这样就能顺利执行apt-get install的命令了
