Error install LinuxCNC to Debian 12

I typed 'raspi' in the search box of file explore but nothing recoverable.  Is please an alternative?

I powered-off and on the PC to boot into Ubuntu 22.04.2 LTS to see if 'raspi' is recoverable because Ubuntu search explorer is more extensive both hard drives.  However, the boot Grub came up instantly and I tried to boot the Ubuntu OS but denied because the kernel needs to loaded.  This wasn't an issue before I installed Debian 12.  I wonder if it has something to do with the xfce-iso.  How do I get the Ubuntu kernel now and will it be recognizable upon booting next time?

Thanks.  I finished installing the latest LinuxCNC.

Now, I still need to load the kernel for Ubuntu.  I see when doing the upgrade in the Debian terminal it showed 'Found Ubuntu 22.04.2 LTS (22.04) on /dev/nvme0n1p2' 'Adding boot menu entry for UEFI Firmware settings ...' 'done'.  The NVMe would be my other internal hard drive and primary OS Ubuntu.  It's files appear intact.  That drive is accessible from Debian 12 either icon select or probably from the Debian directory.  The Ubuntu terminal maybe accessible from its directory too if known what file it's in.  Is a command and which one in the terminal to load the Ubuntu kernel?  Or.  Can it get loaded from the Grub menu and remain recognizable?

How did you get any raspi files onto a amd64 system ? That is the thing that is worrying.

You should be able to choose the Ubuntu system from the grub startup screen, unless you have a timeout that does not allow you to.

This article will help you customise grub.

Funny never happened on the rc releases or stable release of bookworm with me. It has always been a really simple thing. Interesting .......

I'll have to have a look at the Debian Machine upstairs

Sorry I  made an incorrect assumption based on an incomplete description  of the error.
I don't understand why you were using dpkg.

then we come to dkms errors. DKMS compiles drivers on the fly for all kernels in the system so that a kernel upgrade or selecting another on on the system in grub you are covered. But DKMS requires the header files.

I think if Debian made a mistake and included some ARM stuff, it would not be an issue as it would not build under DKMS.

I would not try to use Ubuntu with Linuxcnc. Stay loyal to our Debian partners!

Seems to affect live iso, first post even has a solution. WTF happen at Debian ?????

Net Install seems to be fine, which is what I use.

Cant do this anymore bye all wrote:

Ahh, that's why I have never seen this bug as I only use the net install and that is what's recommended to use in the docs. (which I wrote).

Try and install on other ISO's, distros, Ubuntu, mint at your own risk!

Thanks.  However, the Ubuntu 22.04.01 remains installed.  Disabling Secure Boot at UEFI Firmware Settings allowed me to dual boot.  The Grub might require an update-grub if Secure Boot enabled.  www.linuxfoundation.org/blog/blog/classi...ting-grub-2-on-linux
