Cocould not get lock/var/lib/dpkg/lock-open

I recently studied Ubuntu and used the apt-GET command to install some software packages. the following error occurs: e: cocould not get lock/var/lib/dpkg/lock-open.
This problem may be caused by anotherProgramRunning, causing the resource to be locked and unavailable. The reason for the resource being locked may be that the last installation was not completed properly, resulting in this situation.
Solution: Enter the following command.
Sudo RM/var/Cache/APT/archives/lock
Sudo RM/var/lib/dpkg/lock
Then install the desired package.
