Hi @Eriberto Error you are facing due to libncurses5-dev package which is after PHP 8.x so I guess PHP 8.x is already ignored (as its present in the system).
Is failed to install libncurses5-dev due to dependency error in ubuntu so may be try to install that package by yourself or check if ubuntu already has compatible version present in the system, if yes then remove this package from the list and continue the installation process.
