在linux中sudo vim之后报错：command not found，具体如下

Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)

Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

网上找了很多办法，最终找到下面这两句比较可靠，先执行第一句，再第二句

sudo rm /var/lib/dpkg/lock*

sudo apt-get update && sudo apt-get install vim

之后再执行sudo vim的相关指令就木有问题了
