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

$ apt-get upgrade

Answer 1

你尝试过sudo在命令前面加上吗？像这样：

sudo apt-get update
sudo apt-get upgrade

这对于每个 apt 命令都是必需的，除了 apt-cache 之外。

该sudo命令将暂时将您的权限设置为root 用户，这对于某些程序来说是必要的。

Answer 2

打开终端并运行以下命令：

sudo rm /var/lib/dpkg/lock
sudo apt-get update
sudo apt-get upgrade
