Error DEK is missing after Update to 7.0.6

Post by munger »

Hey
I updated my Virtualbox to 7.0.6 today.
And after that i cant start one of my VMs anymore. I checked the logs and found the error DEK is missing.
I assume that it has something to do with encripting the VM, since my unecrypted vm still works.
The Host system is Windows 10 and i run Ubuntu on the Vm.

The DEK is stored in shrouded form in the .vbox file, so if you deleted that then you must restore it, otherwise the VM is gone for good.

If the DEK seems to be there then try reverting to whatever your previous version was, decrypt, upgrade again and then re-encrypt (if you want).

Also check if you upgraded the Extension Pack to the same version as Virtualbox. The EP enables encryption, and EP / VB versions must match.

Hey thank you very much for the answers. It was a missmatch of versions of extension package and virtualbox.

Good catch. I'll have to remember that one.
