I discovered, confirmed and reported a bug a month or 2 back. I found it in Ubuntu Unity & confirmed it in Xubuntu.
Groovy requires a UEFI ESP partition to be present even on BIOS-based systems which do not have UEFI. This applies on real hardware and also in BIOS-based VMs (the default in VirtualBox).
I filed a bug, posted it on the support mailing list and someone pointed me to an existing bug:
I marked mine as a dup of this.
This is a deal-breaker bug: it prevents installation completing successfully in 100% of cases.
All my machines both at home and work run in legacy-BIOS mode, including ones old enough to only have a legacy BIOS, and all the new ones because UEFI is a pain to use.
This is not a niche or edge case.
It also came up on Reddit yesterday:

This is breaking installation for users in the real world.
The bug is unassigned, so nobody is looking at this and it is unlikely to be fixed in time for 21.04.
This is a serious oversight.
I thought I would raise it here but if there is no resolution in 24 hours – at least someone taking the bug on – I will continue trying to draw attention to it. I am very disappointed that this was shipped and is not being dealt with.
The last time I found a serious bug, it also went unaddressed: in the Unity era, it became impossible to operate LibreOffice menus with the keyboard. This was never fixed.
My email was on Tue, 23 Apr 2013, 19:05 with subject line “LibreOffice menu problem remains”
This is not the kind of attention to detail that I typically expect from Canonical. It is not good.
