Error updating 24xx to, mysgl syntax

hello all i tried to update OJS 2.4.8-5 to, under my server ubuntu 1804, php7.4. when i try to do this i get the following error
“You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'groups ( group_id BIGINT NOT NULL AUTO_INCREMENT, assoc_type ’ at line 1”.
Did the same thing happen to anyone? can anyone help me? thank you!

hola @Juan_Pereyra

¿Podrías montar de nuevo el entorno de actualización?

Nueva bd de ojs 2, nuevo directorio files_dir, nuevo public…

Y ¿Podrías habilitar en el debug = On ?


php tools/upgrade.php check
php tools/upgrade.php upgrade

y pegas entonces aquí la traza anterior al error.
