Right-click on a VM that you're trying to start in the VirtualBox Manager and select "Show Log". Save only the first "VBox.log", ZIP it and attach it to your response (see the "Upload attachment" tab below the reply form).

[Just Fix the address ...

Please attach the image locally in your response (see the "Upload attachment" tab below the reply form). Not a lot of people will go to 3rd party sites. Plus, it's more convenient if the image goes along with the message... And mind you, I speak English, Greek and some French. But in this forum the language is English, so if the picture is not in English, switch to the English interface.

Cannot trust the directory "/usr/lib/virtualbox": group and/or other writable (st_mode=040777)

Something is not right with your system. Does the fact that you run out of space had anything to do with that, like screwing up your filesystem?

I see "install the host from scratch" in your near future...

that is for the people don't want to understand the problem and the right way to fix it

If I had your computer in front of me, I would know how to fix it. Right now I have to imagine what's wrong with your system, huge difference. Since you are sitting in front of your computer and not me, I think that you are better qualified than me to fix your troubles...

The first problem, looks like are just the wrong permissions

That *is* the problem actually, that's why I said you might need to re-install your host OS; because there's no easy way to "reset" the permissions to what they're supposed to be.

I learned long time ago that if you manually mess with permissions the only good thing to come out of it is... nothing, only trouble. And since I don't know what the default permissions for Devuan are, I can't be of help in that front, someone else might be.

If you have another computer that has a working VirtualBox, I would try to install Devuan as a VM and then start comparing permissions between the default VM installation and your host.
