FIXED: VirtualBox downloads giving “Unauthorized Request” error

Last updated on March 13th, 2021

I got an “Unauthorized Request” error when trying to download the VirtualBox 6.0.6 ExtPack (Extension Pack).

There appears to be lots of people seeing the issue, but no published solution, so I thought I’d post my solution. Quite simply: replace the domain name “VirtualBox.org” with “Oracle.com”.

The reason for this is that VirtualBox is owned by Oracle. It appears the server the download comes from is Oracle.com, so the certificate fails your browser security check (the certificate says the site is Oracle.com, but the URL says it’s VirtualBox.org).

Therefore download links are:

Windows: https://download.oracle.com/virtualbox/6.0.6/VirtualBox-6.0.6-130049-Win.exe

OSX: https://download.oracle.com/virtualbox/6.0.6/VirtualBox-6.0.6-130049-OSX.dmg

Linux (Ubuntu): https://download.oracle.com/virtualbox/6.0.6/virtualbox-6.0_6.0.6-130049~Ubuntu~bionic_amd64.deb

6.0.6 Extension Pack (extpack) at: https://download.oracle.com/virtualbox/6.0.6/Oracle_VM_VirtualBox_Extension_Pack-6.0.6.vbox-extpack

I hope that helps!
