I have installed Ubuntu 20.04. Yesterday when I tried to boot my system I got an /dev/sda3: clean .... message.

It seems to check the file system but the numbers didn't change. I waited for it to complete but continued until today. I tried to boot through safe mode, but had no success. what should I do to boot it successfully?

That may be a bug in Ubuntu 20.04, or a failing disk drive.

Try this manual fsck first. It should only take a minute or two.

  • boot to a Ubuntu Live DVD/USB in “Try Ubuntu” mode
  • open a terminal window by pressing Ctrl+Alt+T
  • type sudo fdisk -l
  • identify the /dev/sdXX device name for your "Linux Filesystem"
  • type sudo fsck -f /dev/sdXX, replacing sdXX with the number you found earlier
  • repeat the fsck command if there were errors
  • type reboot

Update #1:

Temporarily try booting with nomodeset...

  • boot to the GRUB menu
  • select the desired boot, probably "Ubuntu", probably already selected
  • hit the "e" key to enter edit mode
  • find "quiet splash"
  • change it to "quiet splash nomodeset"
  • hit control-x or F10 to continue booting
  • if it boots, screen resolution may be off
  • start Additional Drivers, take a screenshot, edit it into your question
  • report back

Here is the steps I followed:

  1. login through TTY3
  2. sudo apt-get purge nvidia*
  3. sudo ubuntu-drivers autoinstall
  4. reinstall display manager, sudo apt install gdm3

This post helped me: "dev/sda1: clean, ..." This message appears after I startup my laptop, then it won't continue booting

This might not be a bug

In my case, it's because I disable the GUI last time before I shutdown my laptop (sudo systemctl stop gdm)

I can still login through TTY with ctrl+alt+f1
