Could not get Lock/var/lib/dpkg/lock-open (11:resource temporarily unavailable) e:unable to lock the administration D I

alexander@alexander-virtual-machine:~$ sudo apt-get install-y httpd
E:could not get Lock/var/lib/dpkg/lock-open (11:resource temporarily unavailable)
E:unable to lock-administration directory (/var/lib/dpkg/), is another process using it?

Solution:

In fact, this is because there is another program running, resulting in the lock is not available. The reason may be that the update was last run or the installation did not complete properly. The solution is to kill the process.
sudo rm/var/cache/apt/archives/lock
sudo rm/var/lib/dpkg/lock

But this does not solve the problem: there may be problems, solutions:

1,sudo dpkg–configure-a

2,sudo apt-get Update
