Background

I'm on VirtualBox 6.0.12. I had a drive which contained a /boot partition, and an encrypted (LUKS) main partition. I wished to remove the encryption and apparently the best way to do this was to migrate Ubuntu to a new drive.

Prior Actions

I used this answer to move the partition contents. I moved both /boot and the main / partition contents. As far as I can tell, it moved it just fine.

As part of step 5 of the above answer, I used the steps below through used of a live CD (no errors reported).

https://askubuntu.com/a/88432/128596

After doing this it seems to boot the Ubuntu partition okay, but got stuck at the (basic looking) Ubuntu 4 dot loading screen (like this one but with 18.04 text).

When I got stuck there, I looked to other answers and I tried to run boot-repair from the live CD but I just got back to the 4 dot loading screen.

Later Events

If I wait for long enough I get dropped to an initramfs screen, and upon trying to exit it I get this behaviour.

Playing around with enabling/disabling 3D acceleration and changing VirtualBox graphics driver don't seem to work.

Question

What actions, if any, can I take to fix this?

boot virtualbox

  Boot the source system to unencrypt all partitions then use this script to clone to a new unencrypted partition: askubuntu.com/questions/1028604/…

  The problem is that there is apparently no easy way to decrypt the partition. askubuntu.com/a/245159/128596 That's why I did the migration to begin with.
