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].
