Invalid signature error in IPA module for VD56G3

[estevan]

Hello.

We're having issues after installing the libcamera package for the VD56G3 sensor from https://www.st.com/en/embedded-software/stsw-img502.html

The ST IPA is (apparently) being treated as untrusted and we're being forced into IPA isolation, crashing the application.

We've already raised the issue at camera_ros and libcamera repos and were directed here.

The discussion started in this issue https://github.com/christianrauch/camera_ros/issues/115

And later moved to https://github.com/raspberrypi/libcamera/issues/258

There's a lot of information in those issues so I'll be brief and not flood you with more logs, and instead wait for your directions/requests.

Thanks.

Hi,

We updated packages, so now you have both the libcamera and libcamera-ipa. Since they're build together they're now signed with the same key and allow the IPA to run without isolation mode.

Could you try it and report if you have new error messages ?

At first, it didn't work because I couldn't install packages that depend on `libcamera0.4.0`.

$ sudo apt install libcamera-dev

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:
The following packages have unmet dependencies:
libcamera-dev : Depends: libcamera0.4 (= 0.4.0+rpt20250213-1) but 0.4.0+rpt20250213+st20250428-1 is to be installed
E: Unable to correct problems, you have held broken packages.

So I unpacked the .deb (from the updated packages) and added this to `/DEBIAN/control`: `Provides: libcamera0.4 (= 0.4.0+rpt20250213-1)`. After repacking and reinstalling, I was able to install `libcamera-dev`.

I forgot to check libcamera-hello before adding libcamera-dev, if I run hello or a ROS2 node, I'm getting WARNs:

I get image, that's the good news, only thing is that for continuously streaming, that warning (that I may be able to silent, is a new thing now).

Glad you got it working.

The WARN is expected. It was hidden when the IPA ran is isolated mode, and now it correctly output warnings.

A better libcamera support is on our roadmap, and will get rid of the warning. You can safely ignore it for now.

The libcamera-dev dependency is more problematic. This might be a solid point to deliver only the whole source code for you to build instead of debian packages, since it's becoming difficult to maintain. Thank you for your inputs.
