Ubuntu Update error--could not get Lock/var/lib/dpkg/lock

When Ubuntu is installed on a VPS, the first command is usually to update the system software. However, in the process of running, there are such errors:

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?

This problem may occur because another program is running, causing the resource to be locked out of service. The reason that the resource is locked may be that the last time you ran the installation or update did not complete properly, and then this situation, the solution is actually simple:
In the terminal, typing the following two sentences
sudo rm/var/cache/apt/archives/lock
sudo rm/var/lib/dpkg/lock

Try to run the apt update again to solve the problem.
