Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires phpbb/epv dev-fix-112 -> satisfiable by phpbb/epv[dev-fix-112]. - phpbb/epv dev-fix-112 requires symfony/console ^5.0 -> found symfony/console[v5.0.0, ..., v5.4.47] but it conflicts with your root composer.json require (~3.4). Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
