I've been trying to install ubuntu server with virtualbox, but the VM always crashes within 10 seconds of starting.

The final log line:

00:00:24.861411 CoreAudio: macOS 10.14+ detected, checking audio input permissions

There's been a few posts that disabling audio in the guest because the host OS needs to or might not be asking or audio permissions.

I don't know the proper fix, though.

For some reason, macOS (Mojave/Catalina) is choosing to kill the VirtualBoxVM process instead of asking for permission.

It might be possible to use tccutil to add "Microphone" permissions to VirtualBoxVM. However:

• You'll have to disable both SIP and AMFI to run tccplus (but I think they can be reenabled afterward)
• I haven't tried this yet so I don't know if it works; on my VMs, microphone is a want not a need, so I'm just sticking with VirtualBox 6.1.12 for the moment
• This still isn't a proper fix -- but if it works, at least it will give you a working microphone, unlike downgrading to VirtualBox 6.1.12
