Overwrite a debian package using dpkg-prebuilt

[SCordibella]

Dear All, I am trying to update a package called wkhtml2pdf because the Debian 12 version doesn't work as I need and there is a version that works as expected published in deb format.

My problem is that I am not able to overwrite the "debian" version of the package.

I create a recipe called wkhtmltopdf and here is the simple content:

inherit dpkg-prebuilt

SRC_URI = "https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6.1-3/wkhtmltox_0.12.6.1-3.bookworm_arm64.deb"
SRC_URI[sha256sum] = "b6606157b27c13e044d0abbe670301f88de4e1782afca4f9c06a5817f3e03a9c"

PV="0.12.6.1-3"

# Only needed if recipe name != package name, as in this case. Or multiple
# packages are provided by a single recipe.
PROVIDES += "wkhtmltopdf"

I change the package inclusion from IMAGE_PREINSTALL to IMAGE_INSTALL, finally I try to force "my" package with this:

local_conf_header:
  fix-wkhtmltopdf-version:
    PREFERRED_VERSION_wkhtmltopdf = "0.12.6.1-3"

Am I missing something?

Thank you for your help,
Stefano.

You probably need to replace IMAGE_PREINSTALL += "wkhtmltopdf" with IMAGE_INSTALL += "wkhtmltox", provided that prebuilt wkhtmltox is actually the same as Debian's wkhtmltopdf.

But what would be better and more sustainable is to work with Debian to update to official package to 0.12.6.1.
