I followed this tutorial to install M5.0.1: [https://mauteam.org/mautic/mautic-admins/mautic-5-installation-on-ubuntu-22-04-with-php-8-1-and-mariadb-11/](https://mauteam.org/mautic/mautic-admins/mautic-5-installation-on-ubuntu-22-04-with-php-8-1-and-mariadb-11/) Than switched to composer with this tutorial: [https://docs.mautic.org/en/5.x/getting\_started/switching\_composer.html#:~:text=Here%E2%80%99s%20the%20steps%20to%20follow%20to%20switch%20to,point%20to%20%2Fvar%2Fwww%2Fhtml%2Fdocroot%20instead%20of%20%2Fvar%2Fwww%2Fhtml%20Altri%20elementi](https://docs.mautic.org/en/5.x/getting_started/switching_composer.html#:~:text=Here%E2%80%99s%20the%20steps%20to%20follow%20to%20switch%20to,point%20to%20%2Fvar%2Fwww%2Fhtml%2Fdocroot%20instead%20of%20%2Fvar%2Fwww%2Fhtml%20Altri%20elementi) Finally I upgrade to M5.0.3 with composer and followed this forum post because some dependencies where missing: [https://forum.mautic.org/t/4-4-10-5-0-1-fails-because-symfony-path-is-not-fount-in-parameterloader-php/30475/9](https://forum.mautic.org/t/4-4-10-5-0-1-fails-because-symfony-path-is-not-fount-in-parameterloader-php/30475/9) --- _[View the full topic](https://forum.mautic.org/t/500-internal-error-when-i-save-and-close-the-e-mail-editor/30995)._
