Ubuntu based VM not booting - Emergency Mode

[chrisx51]

Hi forum,
i just made a bunch of attemps to get ubuntu based Linux distributions running in virtualbox. I already tried Mint, and now I am trying Ubuntu LTS 18.04.

After some reboots and apt-get update processes, I very quickly end up with an error message telling me I am in emergency mode.

The error message

2019-10-07 21_59_28-ubuntu (boot problem nach einrichtung) [Running] - Oracle VM VirtualBox.png (5.71 KiB) Viewed 3594 times

Luckily I just made a snapshot of a running system. But reseting this old snapshot also leads to the same error after shuttind down or reseting this virtualmachine!

Latest logs also attached, so every help is appreciated.
I am stuck

Best regards
Christof

You have assigned all your CPUs to the VM. The host is going to run low on resources, since VirtualBox cares about physical processors (cores), not logical ones (threads).

Go to the VM Settings » Display » Screen. Enable 3D acceleration. Increase the VRAM to the max 128 MB.

But, the error comes from within the guest, it's not a VirtualBox problem as far as I can see...


PS. For future reference you should ZIP your logs. It helps you, it helps us, it helps the server, it helps save a (virtual) tree or two...

He's cutting it pretty close on RAM use too.
