RPI3 + ubuntu-18.04.4 armhf & arm64 => An error occurred

[kinggx9]

I have successfully installed the interface:

sudo apt update
sudo apt upgrade
sudo apt-get install xubuntu-desktop

I have created a new account:

sudo useradd -m -g users -G sudo -s /bin/bash pi
sudo passwd pi

I must mount the boot partition:

sudo fdisk -l
sudo mount /dev/mmcblk0p1 /boot

I continue to install raspi-config :

git clone https://github.com/K0dApan/install_raspi-config
cd install_raspi-config
sudo sh install.sh

Continue: sudo raspi-config Expand Filesystem Boot Options > Desktop/CLI > Desktop Autologin Desktop GUI,... (May be different) Advanced Options > Update Finish Must login with pi account, continue with LCD35-show, must edit some content:

nano /home/pi/LCD-show-ubuntu/LCD35-show
nano /home/pi/LCD-show-ubuntu/rotate.sh
nano /home/pi/LCD-show-ubuntu/system_backup.sh
nano /home/pi/LCD-show-ubuntu/system_restore.sh

The content to be edited: /boot/firmware/* The content is like this: /boot/* Continue:

sudo cp /home/pi/LCD-show-ubuntu/usr/99-fbturbo.conf /usr/share/X11/xorg.conf.d/99-fbturbo.conf
