ubuntu 报错 E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)

比如输入apt-get install eclipse，或者apt-get update ，apt-get install git 会提示

 

E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?

无法打开锁文件 /var/lib/dpkg/lock - open (13: 权限不够)  无法对状态列表目录加锁(/var/lib/dpkg/)，请查看您是否正以 root 用户运行？

解决方案：在命令前加入sudo即可。
