php/laravel - github projects -- upgrading/install/running

Hi.

Been trying to find a few laravel apps from github to get them to run on my
test system

ubuntu 24.04   -- digital ocean instance
php
composer
mysql
etc...
  nothing special

However, I run  into issues with conflicts, and in some cases, conflit with
something that's not in the ctest composer.json from the github app.

So, I backed up a bit, instead of assuming I could simply  download the
app, and rin the
    composer install
using the proj composer.json, perhaps I'm missing something.

When running a fresh/new create proj process, I get a "clean" proj layout
-- files/dirs/etc..  as well as the fresh composer.json.  As expected, the
composer files are different.

My question, one of many, is how do I determine where something like the
following is coming from?

 Problem 1
    - Root composer.json requires laravel/framework v12.10.0 -> satisfiable
by laravel/framework[v12.10.0].


>>>>>>>>>>>>>>>
    - spatie/laravel-html 3.11.1 requires illuminate/support ^10.0|^11.0 ->
satisfiable by illuminate/support[v10.0.0, ..., 10.x-dev, v11.0.0, ...,
11.x-dev].
    - Only one of these can be installed: illuminate/support[v5.1.1, ...,
5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ...,
8.x-dev, v9.0.0-beta.1, ..., 9.x-dev, v10.0.0, ..., 10.x-dev, v11.0.0, ...,
11.x-dev, v12.0.0, ..., 12.x-dev], laravel/framework[v12.10.0].
laravel/framework replaces illuminate/support and thus cannot coexist with
it.

the above err!!

    - Only one of these can be installed: illuminate/support[v11.0.0, ...,
11.x-dev, v12.0.0, ..., 12.x-dev], laravel/framework[v12.10.0]. They all
replace spatie/once and thus cannot coexist.
    - Root composer.json requires spatie/laravel-html 3.11.1 -> satisfiable
by spatie/laravel-html[3.11.1].
