Help with Ubuntu Virtual Machine

[Khadija Kamran]

Hi Outreachy Mentors!

I am an Outreachy applicant and I am part of this community since the
communication period. While I was working on my Virtual Machine, it
accidentally shut down and it has been stuck on boot since then.

This mail is to ask for help with this problem. I have been stuck for
two days and I have tried several slutions but the problem still
remains.

I have windows10 installes and I am using Ubuntu 22.04.1 0n VMWare
Virtual Machine(13GB RAM and 2x4 cores). Here is the error:
-----------------------------------
Gave up waiting for root device. Common problems:
-Boot args (cat /proc/cmdline)
  -Check rootdelay= (did the system wait long enough?)
-Missing modules (cat /proc/modules; ls /dev)
ALERT! UUID=718ed077-947d-4018-80ad-59825678e81d does not exist. 
Dropping to a shell!

BusyBox v1.27.2 (Ubuntu 1:1.27.2-2ubuntu3.2) built-in shell (ash)
Enter 'help' for a list of built-in commands.

(initramfs)_
------------------------------------

I have tried adding rootdelay and I have also tried chaning UUID to
/dev/sda3 (where kernel is installed). I have used the older versions to
run some commands, 'sudo apt-get clean' and 
'sudo update-initramfs -k 6.3.0-rc2+ -u' command, but the problem
remains.

Kindly help me with this problem.

Thank you.

Regards,
Khadija

Hi,

Looks like your kernel missed important kernel configs (did you compile
the kernel yourself?).

You need to see Thorsten's kernel build doc at [1]. tldr: Start with
distribution (Ubuntu) kernel config (find 6.1 kernel config in /boot), then
prepare the trimmed config by `make olddefconfig localmodconfig`. If you
are being asked new config options, just hit Enter to use default value.
You can now launch `make nconfig` to configure the kernel the way you'd like,
but try to be conservative (if you don't understand CONFIG_FOO, leave it alone.

When using localmodconfig, you may need to attach all your devices so that
the appropriate modules are loaded.

Thanks.
