After some experiments and meditation on the process I have found the reason for the installation error in my case.

Somehow -- most likely due to my mistake -- the EFI system partition (ESP) switched to being a logical partition. However, UEFI needs it to be a primary partition. Since I've already broken other OS installations on the machine, I have recreated ESP as a primary partition and Ubuntu 20.04 installed fine after that.

I guess it may be a good idea to add a warning to the partition dialog if such situation is detected.
