After source setup environment, i run:
bitbake imx-image-hovergames-demo -c populate_sdk
I got following errors:

And the i get:

UPDATE
Packages seems to be compiling, but at the end of the image building task, i have:

At the top it says," imx-image-hovergames-demo-20.04-r0 do_populate_sdk: Could not invoke dnf "
I suppose this has to do with the fact that the package manager is RPM?

What could be happenig?
Thanks in advance
