Avant la mise à jours j’ai du lancer une commande :

#  sudo -u www-data php7.3 /usr/share/nginx/nextcloud/occ db:convert-filecache-bigint
[sudo] password for XXXXX:
Following columns will be updated:

* federated_reshares.share_id
* filecache_extended.fileid
* files_trash.auto_id
* share_external.id
* share_external.parent

This can take up to hours, depending on the number of files in your instance!
Continue with the conversion (y/n)? [n] An unhandled exception has been thrown:
Error: Call to undefined method Symfony\Component\Console\Question\ConfirmationQuestion::getAutocompleterCallback() in /usr/share/nginx/nextcloud/3rdparty/symfony/console/Helper/QuestionHelper.php:108

Mais cela plantait à chaque fois … j’ai donc vu qu’il fallait mettre :

# sudo -u www-data php7.3 /usr/share/nginx/nextcloud/occ  db:convert-filecache-bigint  --no-interaction

A noter que par moment les droits sur les logs sont modifiés … et il faut les remettre en place :

# sudo chown www-data.www-data   /var/log/nextcloud.log

A part cela rien d’anormal …
