I followed all the steps exactly as described in the how to, just changing the bootstrap step and sources.list to jammy.
Do you have more information so I can help?
Best regards,
Hi @mvallim thanks for checking this out, I tried again but this time didn't use the sources, I am using the defaults:
deb http://us.archive.ubuntu.com/ubuntu jammy main universe
But I still get the warning:
update-initramfs: Generating /boot/initrd.img-5.15.0-25-generic
W: Couldn't identify type of root file system for fsck hook
Giving more context I am running this within a VM using ubuntu jammy, here is the output of losetup -a
:
# losetup -a

Why in /etc/fstab
you use sda(1|2)
?: (maybe by using the UUID could fix the warning) ?
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/sda2 / ext4 errors=remount-ro 0 1
/dev/sda1 /boot ext4 defaults 0 2
Probably because of this the grub-pc menu doesn't appear, I continue with the setup and ended with:

Installation finished. No error reported.

I manage to create the qcow2
:
qemu-img convert -f raw cloud-ubuntu-image.raw -O qcow2 ubuntu-image.qcow2
But when testing, after booting I get this:
My goal is to create an image only with wireguard but disable cloud-init, I am testing this in Alicloud but I would like to prevent their system to add via cloud-init extra packages, any ideas about how to achieve this?
Hi @nbari,
I run all steps again inside VM (jammy) and any warning or error reported.

Answering your question about cloud-init
, so that nothing is installed through cloud-init
, just don't install the cloud-init
package.

Did you try this?

Hi, I am trying to create an image for ubuntu 22, but I get this error:
Couldn't identify type of root file system for fsck hook
To get sources and packages I did:
And sources:
But I get an error, following the instructions after this step:
