Hello, This still fails on the autobuilders, I'm pretty sure the config for the build folder has: PACKAGE_CLASSES = "package_rpm"
This explains this: build-st-4166614$ tree tmp/deploy/images/qemux86-64/var/lib/ tmp/deploy/images/qemux86-64/var/lib/ ├── dnf │ ├── history.sqlite │ ├── history.sqlite-shm │ └── history.sqlite-wal └── rpm ├── rpmdb.sqlite ├── rpmdb.sqlite-shm └── rpmdb.sqlite-wal 3 directories, 6 files Are you testing with plain poky?
