Using the Ubuntu 64 image https://dl.radxa.com/rockpi/images/ubuntu/rockpi4b-ubuntu-bionic-minimal-20190104_2101-gpt.img.gz
You should be able to
apt-get -y update
apt-get -y upgrade
apt -y dist-upgrade
apt-get install ubuntu-minimal tasksel nano
tasksel to install your your mate version or desktop of choice and any other options from tasksel you wish.
tasksel is a really good common simple console graphical interface that suits all levels of competence and its extremely easy to add new tasks to the list and also means you don’t have to remember package or script names.
Its basically the RockPi4’s Raspi-Config already exists and just needs a few Radxa definitions to make it so.
With the Ubuntu desktop 2 logins needed title header the only thing needed after desktop install was.
echo "[SeatDefaults]" > /etc/lightdm/lightdm.conf.d/12-autologin.conf
echo "autologin-user=rock" >> /etc/lightdm/lightdm.conf.d/12-autologin.conf
Maybe install things incrementally desktop first
reboot and see how it goes
sudo tasksel to add others later.
sudo dpkg -i libjpeg62-turbo_1.5.1-2_arm64.deb
then install chromium I never did really check as it was just a quick fix but prob
apt-get install libjpeg-turbo does the same.
