hello @Siosm and many thanks for doing that!!
On Silverblue 30 beta updates and updates-testing are enabled by default
and i couldnt even disable them, b/c it will break my NVIDIA driver
now im re-trying on a clean SB installation on KVM, but im sure that i’ll get the same errors, but i will try to remove the updates and updates-testing to see if it works then
my OSTree Status i tested on before
