Kali Linux. How to install the program through the terminal?

Question

Kali

I've been on Kali Linux for a couple of days. There is an absolute kettle in the terminal. There was a problem installing the program.
I downloaded VirtualBox, typed sudo apt update in the terminal, then sudo apt install virtualbox-6.0
Gives the message "
The virtualbox-6.0 package is not available, but it is mentioned in the list of dependencies of another package. This may mean that the package is missing, outdated or available from sources that are not mentioned in sources.list
E: No install candidate found for package 《virtualbox-6.0》
Tried apt-get install <package name>, failed to find package using pattern <xxxx>/failed to find package using pattern <xxxx>/ could not find any packages using regular expression <xxxx>.
