Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires ibexa/product-catalog 5.0.x-dev -> satisfiable by ibexa/product-catalog[5.0.x-dev (alias of dev-main)]. - ibexa/product-catalog dev-main requires ibexa/core-search ~5.0.x-dev -> found ibexa/core-search[dev-main, 5.0.x-dev (alias of dev-main)] but it does not match your minimum-stability. - ibexa/product-catalog 5.0.x-dev is an alias of ibexa/product-catalog dev-main and thus requires it to be installed too.
