解决：E: Could not get lock /var/lib/dpkg/lock

问题：

ubuntu16 执行 sudo apt install aria2 命令时，提示如下错误

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?

解决：

sudo rm /var/lib/dpkg/lock
# 如果有出现 /var/lib/list/lock 删除对应的锁定文件即可
