apt update does not work for iMX8M Mini Linux 5.10.9_1.0.0​

[dwhea]

I have built imx-5.10.9-1.0.0.xml according to https://source.codeaurora.org/external/imx/imx-manifest/tree/README?h=imx-linux-gatesgarth:

$ DISTRO=fsl-imx-xwayland MACHINE=imx8mmevk source imx-setup-release.sh -b build-xwayland
$ bitbake imx-image-full

$ DISTRO=fsl-imx-xwayland MACHINE=imx8mmevk source imx-setup-release.sh -b build-xwayland
$ bitbake imx-image-full

however apt update fails:

root@imx8mmevk:~# apt update

In sources/meta-imx/tools/imx-setup-release.sh. Debian package management is added:

echo >> conf/local.conf
echo "# Switch to Debian packaging and include package-management in the image" >> conf/local.conf
echo "PACKAGE_CLASSES = \"package_deb\"" >> conf/local.conf
echo "EXTRA_IMAGE_FEATURES += \"package-management\"" >> conf/local.conf

This change was added in:

It seems Debian package management (apt update, apt-get, etc.) is supposed to work. But from https://community.nxp.com/t5/i-MX-Processors/apt-get-and-apt-key-does-not-work-for-Linux-5-4-XX-for-... : "To add a software package to the linux BSP, you need to add it to local.conf and recompile the image to achieve the goal. The Linux BSP of I.MX is not a standard release version of the debian system, and software packages cannot be installed through apt-get."

Is there support for a "standard release version of the debian system" on Linux I.MX that supports package installation? Are there Yocto recipes that can be added to build in Debian?
