Ubuntu upgrade from v18 using do-release-upgrade

I've been having issues updating ubuntu to the latest version using Hyper-V

I have multiple VMs using Ubuntu 18.04.6 LTS server, and even though I have done latest 'apt-get update' and 'apt-get upgrade' once I do 'do-release-upgrade' and reboot, all I get is:-

I then built a new VM from scratch and tried the same and got the same. I then downloaded Ubuntu 20.1 from the ubuntu website and after install got the same.

I can kinda make out Hyper-V text across the screen, but no idea how to fix it.

The VMs are all Gen2 if that helps

Does anyone have any pointers, Im sure I cant be the first to suffer this, but cant find anything on google about this :-S

Any help???

To me it looks like a Graphic Card issue. Personally I don't use Hyper-V, but other HyperVisors like KVM or VirtualBox. In those you can set different Emulated Graphic cards for the VM, so I suggest looking for such an option within Hyper-V too.

Reading into the issue apparently it maybe a grub issue, but Ive never really played too much with Grub

Likely @rindi is correct, this seems to be a graphic issue.

If I hit this problem, I'd start through the https://LaunchPad.net tickets first, to see if there's a known problem currently in work to be fixed or more likely, someone will have posted a fix.

Ok, after reading multiple search results, I discovered the issue is with grub.

I even found one article which said grub doesnt work with Hyper-V and latest Ubuntu image.

So, I tried a few different boot managers, and figured on refind

So, for anyone coming back on this, this is how I fixed it.

do-release-upgrade

***********************
*DO NOT RESTART AT END*
***********************

sudo apt-get purge grub-pc
sudo apt-get install software-properties-common
sudo apt-add-repository ppa:rodsmith/refind
sudo apt-get update
sudo apt-get install refind


**********OPTIONAL**********
Edit the file to reduce the boot time
sudo nano /boot/efi/EFI/refind/refind.conf

Once booted, delete the first 2 entries by delete key

Open in new window

For information I'm sure if I knew grub more I could possibly fix the issue, but dont so this is a workaround that fixes the issue, Im not saying its the only fix
