Today i released an Image with Kernel 5.3.5 for testing. In case of anyone interested the 8GB Image is here: https://github.com/avafinger/bananapi-zero-ubuntu-base-minimal/releases/tag/v2.4
This is not suitable for those who want to just install and fire a ready Desktop.
It is a bare minimum Image (CLI - Command line Interface) and for those who want to test the cutting edge of Ubuntu 19.10.
Feel free to test and I hope it works for you. Enjoy.
