Hello, I am building the xen minimal image using yocto warrior *("bitbake xen-image-minimal")* by giving the target machine as *"raspberrypi4"*. It reached 99% but at last I got below error and the whole process terminated with error. ERROR: xen-image-minimal-1.0-r0 do_rootfs: Could not invoke dnf.

I have attached screenshot also. *My bblayer.conf file is as below:* # POKY_BBLAYERS_CONF_VERSION is increased each time build/conf/bblayers.conf # changes incompatibly POKY_BBLAYERS_CONF_VERSION = "2" BBPATH = "${TOPDIR}" BBFILES ?= "" BBLAYERS ?= " \ /home/siddhu/Documents/yocto/ sources/poky/meta \ /home/siddhu/Documents/yocto/ sources/poky/meta-poky \ /home/siddhu/Documents/yocto/ sources/poky/meta-yocto-bsp \ /home/siddhu/Documents/yocto/ sources/meta-openembedded/ meta-oe \ /home/siddhu/Documents/yocto/ sources/meta-openembedded/ meta-multimedia \ /home/siddhu/Documents/yocto/ sources/meta-openembedded/ meta-python \ /home/siddhu/Documents/yocto/ sources/meta-openembedded/ meta-networking \ /home/siddhu/Documents/yocto/ sources/meta-openembedded/ meta-filesystems \ /home/siddhu/Documents/yocto/ sources/meta-cloud-services \ /home/siddhu/Documents/yocto/ sources/meta-selinux \ /home/siddhu/Documents/yocto/ sources/meta-virtualization\ /home/siddhu/Documents/yocto/ sources/meta-raspberrypi \ " *My local.conf file I have added the below details:* MACHINE ??= "raspberrypi4" DISTRO_FEATURES += "virtualization xen" PACKAGE_CLASSES ?= "package_rpm" CONF_VERSION = "1" IMAGE_FEATURES += "ssh-server-dropbear" I have tried the same for "cubieboard2" also even there I faced the same issue.Eagerly waiting for the response.
