ubuntu ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCIO.LPCB.HEC.ECRD], AE_NOT_FOUND (20190816/PSARGS-330)
[ 1.679710] ACPI Error: Aborting method \_TZ.TZ00._TMP due to previous error
This 3x then
BusyBox v1.27.2 (Ubuntu 1:2.27.2-2ubuntu3.3) built-in shell (ash)

I am utterly new to Linux and dont care much about data I have on my HP, but would put up to 2 hours to get it.
Thanks in advance.

Because you have given us no information about your PC, or what you actually did prior to encountering this obstacle, there is little for anyone to suggest. We need to know at least your CPU model and GPU model(s). Just guessing here, that you may have tried to install a Linux distribution that is older than your PC. A Linux distribution typically needs to be 6-12 months newer than the hardware technology in the PC. 18 something is 3 or more years old.

The ACPI error probably has no bearing on your problem; I'm seeing something very similar every time I open up my top Linux-compatible laptop...

There must be something else before you get dropped to the busybox shell.

And what mrmazda said obviously.

@ondoho First I enter GNU GRUB version 2.02 where I am offered:
*Ubuntu
Advanced options for Ubuntu
System setup

@mrmazda CPU: Intel Core i3-5005U(2GHz, 3MB cache, 2 Cores), GPU: AMD Radeon R5 M430 Graphics (2 GB DDR# dedicated) Discrete.

I am not sure what I did since it happened around 2 years ago. If I would to guess I probably had music and lot of tabs open.


I also just realized I forgot my password.

You put Ubuntu 18.04 or 18.10 on a 2-3 year old laptop with dual graphics around 2 years ago? Did it work as expected then? And only now it won't boot using the default Grub menu selection? Or, it worked 2 years ago, but now it won't? Did you try any of the advanced options in the menu? Do you still have the installation media, which you could use to try a rescue boot? Where has it been the past 2 years, in an inhospitable location, humid or hot or cold or dusty, or was it protected from animals, children and other possible shocks?

Since 18.04 is nearing 4 years old, the easiest fix might be to upgrade to a newer LTS release, 20.04.

I found this link that talks bout errors like this; https://askubuntu.com/questions/1093...-errors,scroll down to the "Hp / ACPI Errors" section.

You can see if there is a Bios update for your system. It might fix the issue and you can skip the rest.

It mentions a grub option you can pass at boot time to work around the buggy ACPI in your Bios. This involves entering Grub edit mode when you see the grub screen. Press ESC to stop grub countdown, highlight the kernel to edit and press e.
Find the line that starts with 'linux' and move to the end and enter "acpi=off". Press "ctrl x" to boot.
If that does not work, try the option "acpi=strict"

These edits are temporary, see the linked article to make them permanent if one works.

Try if that error still occurs with 21.10.

@OP: if you haven't booted this machine in 2 years, and you know 100% it worked before that, it just might be a hardware problem.


If anything, I'd recommend an LTS version. Why push beta releases on newbies with old hardware.

I tried to boot without root password but failed.
I am going to try find my password tomorrow if that
failes I guess I will try to make it operable with usb somehow.

@mrmazda I possess several usb's. My guess it
experienced - few degrees at worst and no other strain.
@ondoho Yes It definitely used to work.

There is a process known as chroot that can be used to create a new root password:

1. Boot installation or other rescue media
2. Use fdisk -l and/or parted and/or lsblk commands to determine which filesystem is the root filesystem
3. Mount the root filesystem, e.g.:
   Code:

   mount /dev/sda2 /mnt

Proceed:
Reboot into the installed system.

To this, you answered:
I suppose this means you're offered some sort of menu, you choose *Ubuntu, then you get the ACPI errors (which I believe irrelevant), then something more which might be relevant, then the busybox prompt.

Additionally/alternatively you can also press 'e' while in the menu (*Ubuntu) and show us the what you get then.

@mrmazda
I boot ubuntu lst 20.04.3 from usb then I when I procede with installation I an offered option to Erase disk which is going to delete all my files, programs etc. then it gives me additional warning that it will destroy all data on any partitions I have removed as well as on partitions that are going to ve formatted. Then it says what partition tables/partitiond are going to be affected. If I countinue will bypass need for chroot process and aquire a fresh system?
@ondoho
I first enter menu choose ubuntu, then I have to write wrong password 10/15 times and only then I get to see erorr I wrote in OP. I am not sure what is busybox prompt, I was able to access one promt with command "e" and one with command "esc" that is all in GNU GRUB menu before choosinh *Ubuntu

Continuing as you explained will cause complete loss of all data - unless your existing installation has used a separate filesystem for the /home/ location. If a separate filesystem exists for /home/, you can choose during installation that it be used it as is, meaning not to format it. Also, there should be an option early in the "installation" process to upgrade the currently installed system, instead of installing afresh. This too should preserve your existing data. The chroot process is for attempting to repair the installed system. It is not intended for upgrading to a newer version, but in fact might be used to do just that. Moving to 20.04, whether afresh or as upgrade, is probably the better choice for your situation.
