For some labs, you will need 2 Linux VMs. One will be the attacker and the other the victim.
I'd recommend you use Kali and Linux Mint.
To be easier for you I've exported a custom Ubuntu as an OVA file and all you have to do is to import it (double-click on it) in VirtualBox.
Ubuntu 22.04 OVA file (username student and password student). Big file: 5 GB.

Linux Kali OVA file (user kali and password kali)

If you want to enable USB support in your VM you also have to install on your host OS (Windows, Linux, or Mac) Oracle VM VirtualBox Extension Pack:
