FIXED: VirtualBox downloads giving “Unauthorized Request” error
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:
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!
