This version of Nextcloud is not compatible with > PHP 7.4

C’est une erreur – et non un avertissement – qui bloque toutes les commandes suivantes dans le terminal. Elle apparaît lorsqu’une version de PHP plus récente est installée sur votre serveur.

Chez moi, par exemple, j’ai PHP 7.4 pour les sites en production et pour Nextcloud mais aussi PHP 8 pour les plateformes de développement.

Voici le message d’erreur:

This version of Nextcloud is not compatible with > PHP 7.4.

You are currently running 8.0.0

Ce message apparaît parce que Nextcloud lance un rapide php -v pour déterminer la version de PHP installée. Cela ne reconnait par contre que la version la plus récente installée.

Voici ce que donne la commande:

PHP 8.0.0 (cli) (built: Nov 27 2020 12:26:22) ( NTS )
 Copyright (c) The PHP Group
 Zend Engine v4.0.0-dev, Copyright (c) Zend Technologies
     with Zend OPcache v8.0.0, Copyright (c), by Zend Technologies

La solution consiste à modifier manuellement la version retournée par php -v, à l’aide de la commande update-alternatives :

update-alternatives --set php /usr/bin/php7.4

Si on relance php -v, voici le résultat:

PHP 7.4.13 (cli) (built: Nov 28 2020 06:24:59) ( NTS )
 Copyright (c) The PHP Group
 Zend Engine v3.4.0, Copyright (c) Zend Technologies
     with Zend OPcache v7.4.13, Copyright (c), by Zend Technologies

Avec cela, vous êtes parés pour les commandes occ de Nextcloud.

Nextcloud reste bloqué en mode maintenance

Cela peut arriver lors d’une mise à jour, pour diverses raisons.

Solution 1: avec la commande occ

cd /home/www/nextcloud 
sudo -u www-data php ./occ maintenance:mode --off 

Solution 2: éditer le fichier config.php

1. Editez le fichier config.php:

nano /home/www/nextcloud/config/config.php

2. trouvez:

 'maintenance' => true, 

3. remplacez par:

 'maintenance' => false, 

Enregistrez le fichier, l’assistant de mise à jour est alors capable de reprendre là où il s’était arrêté, automatiquement.

La base de données a quelques index manquants

Voici le message d’avertissement complet:

La base de données a quelques index manquant. L’ajout d’index dans de grandes tables peut prendre un certain temps. Elles ne sont donc pas ajoutées automatiquement.

En exécutant “occ db:add-missing-indices”, ces index manquants pourront être ajoutés manuellement pendant que l’instance continue de tourner.

Une fois les index ajoutés, les requêtes sur ces tables sont généralement beaucoup plus rapides.

La solution:

cd /home/www/nextcloud 
sudo -u www-data php ./occ db:add-missing-indices

Résultat:

Check indices of the share table.
 Check indices of the filecache table.
 Check indices of the twofactor_providers table.
 Check indices of the login_flow_v2 table.
 Check indices of the whats_new table.
 Check indices of the cards table.
 Adding cards_abiduri index to the cards table, this can take some time…
 cards table updated successfully.
 Check indices of the cards_properties table.
 Check indices of the calendarobjects_props table.
 Check indices of the schedulingobjects table.
 Check indices of the oc_properties table.

Il manque des clés primaires dans la base de données

Voici le message d’avertissement complet :

Il manque des clés primaires dans la base de données. En raison du fait que l’ajout de clés primaires sur les grandes tables peut prendre un certain temps, elles n’ont pas été ajoutées automatiquement.

En exécutant “occ db:add-missing-primary-keys”, ces clés primaires manquantes peuvent être ajoutées manuellement pendant que l’instance continue de fonctionner.

Certaines colonnes de la base de données n’ont pas été converties en big int

Voici le message d’avertissement complet:

Certaines colonnes de la base de données n’ont pas été converties en big int. Changer le type de colonne dans de grandes tables peu prendre beaucoup de temps, elles n’ont donc pas été converties automatiquement.

En exécutant ‘occ db:convert-filecache-bigint’ ces changements en suspens peuvent être déclenchés manuellement. Cette opération doit être exécutée pendant que l’instance est hors ligne.

Voici la solution:

cd /home/www/nextcloud
sudo -u www-data php ./occ maintenance:mode --on
sudo -u www-data php ./occ db:convert-filecache-bigint
sudo -u www-data php ./occ maintenance:mode --off

Résultat:

 Following columns will be updated:
 federated_reshares.share_id
 filecache_extended.fileid
 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] y

Erreurs Memcache et APCu

Après certaines mises à jour de PHP, j’ai pu obtenir dans certains cas des erreurs de cache local avec APC:

An unhandled exception has been thrown:
OC\HintException: [0]: Memcache \OC\Memcache\APCu not available for local cache (Is the matching PHP module installed and enabled?)

La solution est toute simple, il suffit d’éditer le fichier /etc/php/7.4/cli/conf.d/20-apcu.ini de la configuration cli de votre version de PHP. Je prends PHP7.4 comme exemple ici:

nano /etc/php/7.4/cli/conf.d/20-apcu.ini

Vous n’avez plus qu’à ajouter cette ligne pour activer APCu pour le mode cli de PHP, celui qu’utilise nextcloud:

apc.enable_cli=1

Activer le support SVG pour l’extension php-imagick

À partir de la version 21, Nextcloud affiche un avertissement qui dit que l’extension php-imagick ne possède pas le support pour les fichiers SVG. Si c’est le cas sur votre installation, installez ces paquets:

apt install php-imagick imagemagick

Résultat:

The following NEW packages will be installed:
  imagemagick imagemagick-6.q16 libdjvulibre-text libdjvulibre21 libilmbase24 libmagickcore-6.q16-6-extra libnetpbm10 libopenexr24 libwmf0.2-7 netpbm php-imagick

Voilà pour les erreurs communes que j’ai déjà rencontrées. J’espère que cela peut vous aider si vous tombez vous-aussi dessus!

    Bonjour
    Merci bcp pour avoir mis les requetes SQL ! J’ai enfin pu corriger les bases de données.
    J’ai toutefois encore quelques soucis sur mon instance :
    * Des index manquants
    * Colonnes de la base de données n’ont pas été converties en big int
    Voici une capture d’écran : https://cln.sh/BvDqCco0lodXRtPX8ur4

    Lorsque je veux utiliser les commandes OCC via SSH, mon syno répond que la version de PHP détecté est 5.6 alors que je suis sur un 7.4 (il s’agit d’un bug) et je ne parviens donc pas à utiliser les commandes.
    La solution d’executer les commandes SQL m’a déja bcp aidé, mais pourriez vous me donner les commandes a utiliser pour ces 2 items pour tout pouvoir corriger ?

    Merci :-)

    Bonjour,
    Pour les index et clef primaire manquants, pourriez vous SVP nous donner les requete SQL à passer? En effet, je n’ai pas les accès SSH et ne peut donc pas exécuter les lignes indiquées.
    Merci !

      Bonjour,

      Pour les indices manquants:

      ALTER TABLE `oc_properties` ADD INDEX `properties_path_index` (`userid`, `propertypath`) USING BTREE;
      ALTER TABLE `oc_comments` ADD `reference_id` VARCHAR(64) NULL DEFAULT NULL;
      ALTER TABLE `oc_filecache_extended` MODIFY `fileid` BIGINT(20) UNSIGNED NOT NULL;

      Pour la clé primaire:

      ALTER TABLE oc_federated_reshares ADD PRIMARY KEY (share_id);
      ALTER TABLE oc_systemtag_object_mapping ADD PRIMARY KEY (objectid, objecttype, systemtagid);
      ALTER TABLE oc_comments_read_markers ADD PRIMARY KEY (user_id, object_type, object_id);
      ALTER TABLE oc_collres_resources ADD PRIMARY KEY (collection_id, resource_type, resource_id);
      ALTER TABLE oc_collres_accesscache ADD PRIMARY KEY (user_id, collection_id, resource_type, resource_id);
      ALTER TABLE oc_filecache_extended ADD PRIMARY KEY (fileid);

      Notez que d’autres tables peuvent être concernées, tout dépend de votre version de Nextcloud et des tables concernées par votre mise à jour.
