How to force a reinstall of the system

[Olivier]

Hello,

I am running a minimal version of Ubuntu on a single board
computer. There is no complete version of Ubuntu available for that SBC.

I have spent some time trying to install all I need to turn it into a
normal Ubuntu, but some bits and parts are missing that I cannot manage
to locate.

Is there a way to force a complete installation of Ubuntu (desktop
version) on a system? Like
"apt-get insall all-that-is-missing-to-make-normal-Ubuntu"

Thanks,

Olivier
