Navigate to the nextcloud directory and enable maintenance mode:
sudo -u www-data php occ maintenance:mode --on
sudo rsync -Aax /var/www/nextcloud/ ~/nextcloud-dirbkp_`date +"%Y%m%d"`
mysqldump --single-transaction -u user -p nextcloud > ~/nextcloud-sqlbkp_`date +"%Y%m%d"`.bak
From the upgrade docs:
Instead of clicking that button you can now invoke the command line based updater by going into the updater/ directory in the Nextcloud directory and executing the updater.phar as the web server user.
The Nextcloud CLI updater.phar routine does not like the presence of Let's Encrypt's .well-known directory. A simple strategy is to just move it out of the web root for the duration of the upgrade, and restoring it to it's original location when done. Alternatively it would be feasible to serve the .well-known directory from a different path via a web server config.
sudo -u www-data php updater.phar Nextcloud Updater - version: v13.0.0beta1 Current version is 13.0.0. Update to Nextcloud 14.0.1 available. (channel: "stable") Following file will be downloaded automatically: https://download.nextcloud.com/server/releases/nextcloud-14.0.1.zip [...] Start update? [y/N] y Info: Pressing Ctrl-C will finish the currently running step and then stops the updater. [✘] Check for expected files failed The following extra files have been found: .well-known Update failed. To resume or retry just execute the updater again.
The update went off without a hitch after temporarily moving the .well-known directory from the Nextcloud root:
sudo -u www-data php updater/updater.phar [...] Maintenance mode is disabled
sudo -u www-data php occ maintenance:mode --off
Sometimes when updating various table indexes are skipped, this will add them after an update.
sudo -u www-data php occ db:convert-filecache-bigint
If you happen to be changing PHP versions along with upgrading Nextcloud, remember the list of PHP modules required by Nextcloud; listed here: https://docs.nextcloud.com/server/16/admin_manual/installation/source_installation.html#prerequisites-for-manual-installation.
The following message appeared in the admin dashboard:
The database is missing some indexes. Due to the fact that adding indexes on big tables could take some time they were not added automatically. By running "occ db:add-missing-indices" those missing indexes could be added manually while the instance keeps running. Once the indexes are added queries to those tables are usually much faster. Missing index "share_with_index" in table "oc_share". Missing index "parent_index" in table "oc_share". Missing index "fs_mtime" in table "oc_filecache".
I added the indices with the following command:
sudo -u www-data php occ db:add-missing-indices Check indices of the share table. Adding additional share_with index to the share table, this can take some time... Share table updated successfully. Adding additional parent index to the share table, this can take some time... Share table updated successfully. Adding additional mtime index to the filecache table, this can take some time... Filecache table updated successfully.
Ran into the missing indexes problem again during this update, and used the
occ db:add-missing-indices command to add them manually.
sudo apt install php-imagick
Some columns in the database are missing a conversion to big int. Due to the fact that changing column types on big tables could take some time they were not changed automatically. By running 'occ db:convert-filecache-bigint' those pending changes could be applied manually. This operation needs to be made while the instance is offline. For further details read the documentation page about this. activity.activity_id activity.object_id activity_mq.mail_id filecache.fileid filecache.storage filecache.parent filecache.mimetype filecache.mimepart filecache.mtime filecache.storage_mtime mimetypes.id storages.numeric_id
sudo -u www-data php occ db:convert-filecache-bigint Following columns will be updated: This can take up to hours, depending on the number of files in your instance! Continue with the conversion (y/n)? [n] y

You are using a fallback implementation of the intl extension. Installing the native one is highly recommended instead. at /var/www/nextcloud/3rdparty/patchwork/utf8/src/Patchwork/Utf8/Bootup/intl.php#18
