Add the grub arguments noapic noacpi nosplash in place of quiet splash. noapic and noacpi are kernel boot options. ACPI stands for Advanced Configuration and Power Interface and APIC stands for Advanced Programmable Interrupt Controller.
Immediately after the motherboard / computer manufacturer logo splash screen appears when the computer is booting, with BIOS, quickly press and hold the Shift key, which will bring up a GNU GRUB menu screen. With UEFI press (perhaps several times) the Esc key to get to the GNU GRUB menu screen. Sometimes the manufacturer's splash screen is a part of the Windows bootloader, so when you power up the machine it goes straight to the GNU GRUB menu screen, and then pressing Shift is unnecessary.
You will see a GNU GRUB menu screen that looks like this:
Press e to enter editing mode. This will bring up a GNU GRUB screen that looks like this:
Use the arrow keys to navigate when screen editing the above screen. Navigate to after the string on this screen that starts with root=. In this example screen the full string is root= followed by UUID= and a hexadecimal string as shown below:
root=UUID=bcf15ef2-a0b2-4753-9558-8399dd12a729
Immediately after this string replace quiet splash by noapic noacpi nosplash. This change is only temporary — it will just be used once and GRUB won't remember it in the future. It may be possible to make these changes permanent by changing the ACPI and APIC settings in the Mac Mini's UEFI firmware. Press Ctrl+X or F10 to boot with the kernel boot options that were added. If you make a mistake, press Esc to go back to the previous screen.

@karel What happens if there is no line that says "root"? (I am not using a Mac Mini, is it specific to that hardware?) – ComputerScientist Sep 24 '20 at 19:24

@ComputerScientist The GNU GRUB screen is not specific to Mac Mini hardware. For another example of a similar GNU GRUB screen on Debian see this answer. For an example of a different type of boot screen on openSUSE Leap see this answer. – karel Sep 24 '20 at 23:36

What does this do? For me it still goes into recovery mode, the error is still there in
journalctl -xb. – Yan King Yin Apr 03 '22 at 18:53 -

Use a live usb of the same ubuntu version.
Open terminal.
sudo -i
fsck /dev/sdaX
Replace 'X' with your root disk name,and then with all other drives present.
You can check it with "fdisk -l".
Reboot.Remove live usb.
Ta-da, its done.

1You don't need live CD :) just press Enter and you will have root, then do fdisk and fsck :) – madzohan Jun 04 '20 at 23:02
