Libcamera on Ubuntu

I am using Ubuntu 23.04 and I am just trying to get libcamera-hello --list-cameras to work to see if it can identify my arducam pivariety low light camera module for RPI (SKU: B0333). The paper that came with the camera said in order to install the driver I should do
wget -O
chmod +x
./ -p kernel_driver
Then it says press y to reboot but there is no option to do that. I read on another forum that the last line should be changed to
./install_pivariety_pkgs -d
I also did this and the option to reboot did come up (however it said in the forum that it wasn’t needed, I did anyway for extra security). Next it says to see if the driver was downloaded using
dmesg | grep arducam
however I need to use
sudo dmesg | grep arducam
yet when I do this nothing comes up but it runs. So, this is where my first red flag came up, yet I still tried to install the libcamera app installation. ./ -p libcamera_dev and ./ -p libcamera_apps
These seemed to download, but there is no libcamera directory made from this. I could not do libcamera-still or libcamera-hello. Neither of these commands work.

I also tried to install libcamera from source code because it was giving me trouble. I followed software installation - libcamera is missing in Ubuntu aarch 64, raspberry pi - Ask Ubuntu but ninja gave me trouble, so I did it separately with using ninja-build instead of ninja.
sudo apt install build-essential meson libyaml-dev python3-yaml python3-ply python3-jinja2 libssl-dev openssl git
sudo apt install ninja-build
git clone
cd libcamera
meson build
sudo ninja -C build install
This did create a directory called libcamera; however, it didn’t create a libcamera-apps directory. When I tried to run libcamera-hello --list-cameras it said the command could not be found. Hence I am stuck and I do not know how to get this camera running on Ubuntu.

I was not able to get the upstream or rpi versions of libcamera-apps working on Ubuntu.

After talking to the person maintaining the rpi fork, they released a libcamera-apps update that brought the rpi libcamera and libcamera-apps repos into sync - and i was able to get it to work on Ubuntu.

Note: the overlay system is different between Raspian and Ubuntu.
On Raspian, it’s at /boot; on Ubuntu, it’s at /boot/firmware.

Once you’re in the right path, check the overlays folder: ls /boot/firmware/overlays/imx*
to see if your camera driver is there. If not, you’ll need to find/build your camera’s dbto driver.

Once you have your driver, you’ll need to enable it in your /boot/firmware/config.txt file.

I don’t have an imx* folder but I did find all the different imx* files in the overlays folder. I am using the imx462 with RPi pivariety low light camera (SKU: B0333), so I located the file imx462.dtbo.bak, imx462.dtbo, arducam-pivariety.dtbo.bak, and arducam-pivariety.dtbo.

In the config.txt file I went to the bottom and inserted the lines dtoverlay=arducam-pivariety and dtoverlay=imx462. From my understanding the .dtbo.bak files are backups so I do not need to have redundancies in the code, so I didn’t add them. Yet when I rebooted the pi and tried to do libcamera-hello it still said the “command not found”.

Sorry - typo on my part - fixed.

I was not able to get the libcamera/libcamera-apps to work on Ubuntu from the package installers mentioned by ArduCam on:

Others may have success doing so, but I ended up building from source.

Note when building from source:

I ended up going with the RaspberryPi fork. At the time, the RPI libcamera and libcamera-apps repos were out of sync. After a bug report, the maintainers updated libcamera ( raspberrypi/libcamera-apps@3d9ac10) which fixed that problem.

Once you get a synchronized libcamera and libcamera-apps installation, you should be able to call libcamera-hello.

Note: once I did this, I still had 2 remaining issues: I had to get the previewer to work. That involved a) building libcamera with the correct build options (see the repo READMEs), and setting up my boot/firmware/config.txt to correctly set up the display. Then I needed to find the correct imxXXXX.dtbo driver and configure that in config.txt file.

If I get access to ArduCam’s Wiki, I’ll add these instructions for getting this to work on Ubuntu. Otherwise, I’ll add a forum topic.

Did you have any additional luck on getting the libcamera software working on Ubuntu 22? I’m struggling and could use some additional insight.
