Build aditional modules for vyos, linux-source package

Hi,
regarding to this article: https://wiki.vyos.net/wiki/Build_procedures - I’m looking for linux-source package.
In the following location, there is no linux-source deb package:
http://dev.packages.vyos.net/repositories/current/pool/main/l/linux-4.19.134-amd64-vyos/

Is there any other location?
Is the vyos kernel modules building procedure still valid?
I’m using ver 1.3

Another question: Is is possible to install packages from Debian repository?

Thanks in advance for any hints.

Hi @silencer,
We no longer keep a fork of the kernel source, since we no longer need to patch it as heavily as we once had to.
You can find the kernel package build scripts at https://github.com/vyos/vyos-build/tree/current/packages/linux-kernel

Hi @dmbaturin
Thanks for the explanation!
I’ve successfully build linux-image package. Now I got following issue when I tried to install it:

dpkg -i linux-image-4.19.134-amd64-vyos_4.19.134-1_amd64.deb

It looks like there is a problem with /usr/sbin/grub-probe which not recognized overlay filesystem.
What is the “feng shui” with kernel deb package installation?
Is there any wiki describing this procedure?

I appreciate your help!

Any ideas, how to install linux-image package?

Hello @silencer, you can check is kernel added to /boot

 sudo ls -la /boot/

and try to update initramfs manually

sudo /usr/sbin/update-initramfs -u

Tell me if this works for you, in another case I will try to reproduce it locally

Hi Dmitry,
thanks a lot for the suggestion.
Looks like that start update-initramfs manually works well:
update-initramfs -u -k all

live-boot: core filesystems devices utils udev wget blockdev.

live-boot: core filesystems devices utils udev wget blockdev.

Unfortunately, dpkg left unconfigured packages, so there is a little mess in OS:

What I did wrong?
I appreciate your help.

Hello @silencer, I think you need to try to build kernel like this does vyos-build

Hi Dmitry,
that’s exactly what I did, and the kernel was built without any issues.
The problem is with installation of linux image deb package, because of read only filesystem.

I appreciate your help.

Hi @silencer, can you confirm that you have and trying to install on the installed image.
Provide, please an output of the command show version

Hi Dmitry,
thanks for your reply.

Hello @silencer, try this hack

sudo mv /etc/kernel/postrm.d/zz-update-grub /etc/kernel/postrm.d/zz-update-grub.back

And try to install again

sudo dpkg -i linux-image-4.19.134-amd64-vyos_4.19.134-1_amd64.deb
