Problem 1

• gedmo/doctrine-extensions[v2.3.4, ..., v2.3.9] require doctrine/common >=2.2,<2.5-dev -> found doctrine/common[2.2.0, ..., v2.4.3] but the package is fixed to 3.1.1 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
• gedmo/doctrine-extensions[v2.3.10, ..., v2.4.42, v3.0.1] require doctrine/common ~2.4 -> found doctrine/common[v2.4.0, ..., 2.13.3] but the package is fixed to 3.1.1 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
• gedmo/doctrine-extensions v3.0.0 requires php ^7.2 -> your php version (7.1.26) does not satisfy that requirement.
• gedmo/doctrine-extensions[v3.0.2, ..., v3.0.3] require php ^7.2 || ^8.0 -> your php version (7.1.26) does not satisfy that requirement.
• stof/doctrine-extensions-bundle v1.5.0 requires gedmo/doctrine-extensions ^2.3.4 || ^3.0.0 -> satisfiable by gedmo/doctrine-extensions[v2.3.4, ..., v2.4.42, v3.0.0, v3.0.1, v3.0.2, v3.0.3].
• Root composer.json requires stof/doctrine-extensions-bundle 1.5 -> satisfiable by stof/doctrine-extensions-bundle[v1.5.0].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.
