Ubuntu 18.04 apt-get Install xxx 时出现 (E: Could not get lock /var/lib/dpkg/lock.....)问题解决

在为ubuntu 18.04 安装SSH服务时，

sudo apt-get install openssh-server

遇到了

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?

的问题。

 

解决办法：检索一下 apt的进行，并Kill掉。

sudo ps -aux | grep apt
sudo kill -9 12078

重新安装，OK。
