Couldnotgetlock/var/lib/dpkg/lockfrontend

在安装软件包时如果出现Could not get lock /var/lib/dpkg/lock-frontend&＃xff0c;说明之前使用apt时出现异常&＃xff0c;没有正常关闭&＃xff0c;还在运行。

lgj&＃64;lgj-Lenovo-G470:~$ sudo apt-get install alien
[sudo] password for lgj:
E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

解决&＃xff0c;使用ps 和 grep查找apt的pid,并使用kill杀死掉。

lgj&＃64;lgj-Lenovo-G470:~$ ps afx|grep apt
16214 ? S 0:00 \_ sudo apt install rpm
16215 ? S 0:01 | \_ apt install rpm
16721 pts/3 S&＃43; 0:00 \_ grep --color&＃61;auto apt
lgj&＃64;lgj-Lenovo-G470:~$ kill 16214
bash: kill: (16214) - Operation not permitted
lgj&＃64;lgj-Lenovo-G470:~$ sudo kill 16214
lgj&＃64;lgj-Lenovo-G470:~$ sudo kill 16215

执行安装指令

lgj&＃64;lgj-Lenovo-G470:~$ sudo apt-get install alien
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

  如果仍然出现&＃xff0c;需要手动删除 /var/lib/dpkg/lock即可。

sudo rm -rf /var/lib/dpkg/lock

sudo rm -rf /var/lib/dpkg/lock-frontend
