Error installing virtualbox downloaded from the virtualbox site

Downloaded virtual box .deb file for Ubuntu installation.
Received error about unsandboxed installation.

The solution to the error is to provide the _apt user the rights to write into the folder as shown below:

$ sudo chown -Rv _apt:root /var/cache/apt/archives/partial/ <enter>
$ sudo chmod -Rv 700 /var/cache/apt/archives/partial/ <enter>
