all attempts to copy files fails about cubic HOT 4 OPEN

You may be taking the wrong approach by trying to copy files and configure the package after installation.

App Image

Instead of copying files after installation, use a template for the home directory for all new users.

1. In Cubic's Terminal Page, create a Desktop directory in /etc/skel, if it does not exist, and then cd into the new directory.

   mkdir /etc/skel/Desktop
   cd /etc/skel/Desktop
   

2. Drag and drop the file software.AppImage onto the Terminal Page to copy it into the Desktop directory.

3. When the new user ubuntu is created, software.AppImage will be automatically copied to /home/ubuntu/Desktop and the correct ownership ubuntu:ubuntu will be asigned.

LightDM

Instead of configuring LightDM after installation, try to configure it while you are cusomizing the OS by executing the following command in Cubic's Terminal Page.

DEBIAN_FRONTEND=noninteractive dpkg-reconfigure lightdm

I found the error code in the crash report. It says invalid user ubuntu. Should ubuntu user exist by now when running late-commands ?

I have little experience with cloud-config. However, using preseed, I found that late_command does not work in Ubuntu, and success_command should be used instead. Perhaps this is similar for cloud-config as well?

Here is an example of how I update grub and copy a custom grub config file after installation, using preseed. Notice, only one success_command is allowed, so it is necessary to string all of the commands together using semicolons (;). Could this also be a requirement for cloud-config?

ubiquity ubiquity/success_command string \
    in-target bash -c 'update-grub'; \
    in-target bash -c 'cp /usr/share/grub/default/grub /etc/default/grub';

Also, why do you need the sudo command at this point in the installation? The installer is already running with root privileges. Perhaps this is why you are seeing the ubuntu user error?

Oh cool thank you I will give a shot
