  • Is that the correct repository url? Are you trying to install virtualbox and manually added it to your apt sources or did it suddenly break? Check out "Debian-based Linux distributions" here. – frippe Jul 28 '22 at 11:38

The entry in your /etc/apt/sources.list or /etc/apt/sources.list.d/... is incorrect. It should be

deb [arch=amd64] https://download.virtualbox.org/virtualbox/debian focal contrib

The domain is download.virtualbox.org, not www.virtualbox.org.
