I know this has been asked before,but I don't have the technical know-how to perform any of the fixes nor do I know where to start. I turn my laptop on and it boots up to the GNU Grub whereas before it would just boot up automatically to Ubuntu then I choose Ubuntu and the statement "cryptsetup: Waiting for encrypted source device UUID=XX...." and then it goes into the busybox shell so then what would I do then?

I had exactly the same error message / behavior on my Dell XPS15 P56F - the issue was that the system configuration was set for SATA operation to RAID instead of AHCI. Somehow that got changed by itself, Maybe because the battery died and I didn’t use the computer for a while and hence all power supply went completely flat.

reboot and go to BIOS using "fn and F2" or "F12" Go to ‘System Configuration’ > ‘Sata Operation’ > switch to "AHCI" from "RAID On"

    Got the cryptsetup: waiting for encrypted source device on a Dell XPS 9370 with ubuntu 20.04 that hadn't been booted in many months. The BIOS SATA setting had been switched to RAID. Switching it to AHCI fixed things! – Daniel Himmelstein Sep 05 '22 at 22:49

    Same issue for a Dell after letting the battery run out! Thanks! – Pâris Douady Sep 12 '22 at 07:34
  • This resolved my issue after my battery died on a Dell XPS 15 7590. Changing the setting back in BIOS allowed for boot to properly access and decrypt. You will get a warning that the system may become unbootable in the event that your system is not meant to be using AHCI, and that you may have to reinstall. So, for those giving this a shot, would be good to keep in mind in case this may not be your issue or the proper solution depending on the root cause. – ScriptAutomate Feb 06 '23 at 01:14

  • What the is going on. My laptaop also changed this by itself after the battery run out. Thanks. – Ini Mar 19 '24 at 15:57
