DELL 7440 camera still not working ubuntu 22.04

rubi1200 · July 31, 2025, 5:31pm

You should run sudo apt upgrade instead.

If it returns errors, post them here please.

federicarike · July 31, 2025, 5:56pm

We are going to purge all the packages anyways, so do not worry for those listed.

But yes, switch to the sudo apt upgrade command, as @rubi1200 suggested!

Then go with the other two and reboot, please.

After that let us purge and reboot again:

sudo apt autopurge oem-*-meta libia-* libgcss* libipu* libcamhal*
sudo apt autopurge lib*ipu6*
sudo apt autopurge lib*ipu7*
sudo reboot

Now we should be able to reinstall the packages without mess around.

hibarel · July 31, 2025, 6:07pm

listing the errors here

Errors were encountered while processing:
 libcamhal-common
 libcamhal0
 gstreamer1.0-icamera
 libcamhal-ipu6ep0
E: Sub-process /usr/bin/dpkg returned an error code (1)

and continuing with the autoclean and autoremove followed by everything else in federicarike’s reply below.

hibarel · July 31, 2025, 6:18pm

I’ve done it all.
The last command sudo apt autopurge lib*ipu7* returned this error:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package lib*ipu7*
E: Couldn't find any package by glob 'lib*ipu7*'

and I went ahead with the reboot.

federicarike · July 31, 2025, 6:22pm

Great! No worries, it is just saying you were having no ipu6/ipu7 installed.

Alright! So now let us have a look at the list of drivers

sudo ubuntu-drivers list

Please post the output here Thanks!

hibarel · July 31, 2025, 6:23pm

OK
This is the output of drivers list:

oem-fix-misc-cnl-backport-iwlwifi-helper
libfprint-2-tod1-broadcom
oem-somerville-lapras-meta
libcamhal0

federicarike · July 31, 2025, 6:24pm

Alright, let us now install the repository for the OEM metapackage:

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

and install the last two packages in the list, @hibarel :

sudo apt install oem-somerville-lapras-meta
sudo apt install libcamhal0

then reboot, if you like.

It should be all set and running afterwards.

Please test the MIPI camera here: https://mozilla.github.io/webrtc-landing/gum_test.html

Or with cheese!

hibarel · July 31, 2025, 6:30pm

federicarike · July 31, 2025, 6:33pm

Ops! A little more patience …

For the OEM metapackage error, we need to install the stable repository (I edited the instructions above for the future readers, so you guys have already done this step):

Add the Ubuntu 22.04 Dell OEM metapackage repository

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

[sorry I completely overlooked this was not in your list alongside the ppa repository we removed, @hibarel!]

Then:

sudo apt-get update && apt-get upgrade
sudo apt-get autoclean
sudo apt-get autoremove
reboot

Now that we have the right repository, we install the OEM metapackage for DELL Latitude 7440:

sudo apt install oem-somerville-lapras-meta

Now let us install the generic modules:

sudo apt-get install --no-install-recommends --yes \
    linux-generic-hwe-22.04 \
    linux-modules-ipu6-generic-hwe-22.04 \
    linux-modules-usbio-generic-hwe-22.04

and the required HAL one

sudo apt install libcamhal0

Let me know what happens.

In case of further issues with libcamhal-common:

sudo apt install libcamhal-common
sudo apt install libcamhal0

hibarel · August 1, 2025, 10:57am

Thanks! (sorry for the gap, I went to sleep )
OK, I followed all the steps again in this post.
I got the same error after the command:
sudo apt install oem-somerville-lapras meta

Reading package lists... Done

libcamhal0

How to continue?

federicarike · August 1, 2025, 11:13am

No worries! We should also sleep hahah

Little typo in the command (there is a - between lapras and meta). Try this @hibarel !

sudo apt install oem-somerville-lapras-meta

Perhaps running this might help?

sudo dpkg --configure -a

This will attempt to fix any broken or partially installed packages.

sudo aptitude build-dep libcamhal0

In case aptitude is not installed

sudo apt-get install aptitude

Actionparsnip · August 2, 2025, 9:06am

Is this the webcam in question? Just to check

hibarel · August 3, 2025, 7:40am

No, its an external logitech USB cam that I use (since the built in intel camera doesnt work)
