I can't install Magento any further, how can I solve this problem
Have you installed the ext-sodium extension? Please check system requirements https://devdocs.magento.com/guides/v2.4/install-gde/system-requirements.html
Thanks
If you're having trouble with the installation, check your internet connection and try restarting the setup. If that doesn't fix it, get some help with the error message you're getting.
