Upgrading Drupal

Hello everyone,

While the composer update runs fine, when I'm back on the updated Drupal I get an error message.

/var/log/apache2/error.log gives a clue but I don't understand it :

This is just a simple suggestion for those looking to migrate geofield data from Drupal 7 to 8.  As the migration entity for such a migration is not yet ready and this migration was a show stopper for me so I stepped back to a simple mysql method.  

After the migration of 7.59 to 8.5.6, with nothing modules activated, i have one error to try configure in 

"/admin/config/system/site-information" the default homepage of the  site, i put the "/node/foo" and with clean urls and the same problem, 

how i can redirect to "<front<"?

thanks

I'm trying to update from 8.5.4 to 8.5.6.  I follow the instructions, deleting core and vendor directories and all files in the root.  I copy the new version over then run update.php.  It tells me there are no updates, and the report page says I'm still on 8.5.4! 

What am I missing?
