You can also use the release built by CI from https://github.com/armbian/os/releases/tag/23.11.0-trunk.15
Although I have installed Armbian_23.11.0-trunk.15_Rock-5b_lunar_collabora_6.5.0-rc1_minimal and it, like all the current releases except legacy, do not boot/show a display. Is this likely a uboot issue or is there an issue occurring within the image build process?
I think the last image I could find that wasn't legacy that could boot was Armbian_23.8.0-trunk.309_Rock-5b_lunar_midstream_6.2.0-rc1_minimal, albeit the pci-e wasn't working correctly as the intel wifi chip errored.
