Hi @alenzadeh,

let us purge the packages and fresh install the whole business

sudo add-apt-repository --remove ppa:oem-solutions-group/intel-ipu6
sudo add-apt-repository --remove ppa:oem-solutions-group/intel-ipu7 
sudo apt autopurge oem-*-meta libia-* libgcss* libipu* libcamhal*
sudo apt autopurge lib*ipu6*
sudo apt autopurge lib*ipu7*

Then

sudo add-apt-repository "deb http://dell.archive.canonical.com/ noble somerville"
sudo apt-get update

Then

sudo ubuntu-drivers list

Install the ones in your output list here (one should be oem-somerville-oddish-meta)
with sudo apt install [package name]

[alenzadeh]

Thanks for your help .I’ve followed all those and all purged.

still no luck and the camera is not working.

@alenzadeh Have you installed all the packages in the list?

intel-usbio-dkms
oem-somerville-oddish-meta
libcamhal0
intel-ipu6-dkms

I installed mine in the order they were displayed and then rebooted.
Let me know what happens.

[alenzadeh]

$ sudo v4l2-ctl --list-devices
ipu6 (PCI:pci:pci0000:00):
	/dev/video1
	/dev/video2
	/dev/video3
	/dev/video4
	/dev/video5
	/dev/video6
	/dev/video7
	/dev/video8
ipu6 (pci:pci0000:00):
	/dev/media0
Intel MIPI Camera (platform:v4l2loopback-000):
	/dev/video0

installed all the packages in the list in the same order, rebooted, camera is listed but does not function.

[federicarike]

And these should also be there @alenzadeh

sudo apt-get install --no-install-recommends --yes \
    linux-generic-hwe-24.04 \
    linux-modules-ipu6-generic-hwe-24.04 \
    linux-modules-usbio-generic-hwe-24.04

Was the camera working? Have you checked it is enabled in the BIOS?
No camera lens cover on it or any deactivating key pressed?
