Problems with the installation of VirtualBox on Ubuntu 20.04.1 LTS

Question

just so you know I'm pretty new at Linux.

I just made the jump from Ubuntu 19.10 to Ubuntu 20.04.1 LTS because I thought there wouldn't be a problem with VirtualBox. When the upgrade was finished I noticed VirtualBox was gone, I tried to install it following the instruction on the official website and other sites.

I don't know what you guys exactly need to help me solve the problem so here's some informations :

Here's what appears when I do sudo apt update :

I did

$ wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -
$ wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add -

and

echo "deb [arch=amd64] http://download.virtualbox.org/virtualbox/debian $(lsb_release -cs) contrib" | 
     sudo tee -a /etc/apt/sources.list.d/virtualbox.list

without any problems.

I hope everyone is having a good day :)
