– Nextcloud 15.0.7

---

Nextcloud can be updated using the Nextcloud command line interface only. Even your enabled apps will be updated as far as they are available on the Nextcloud app store. First backup your Nextcloud system (database and data). Then keep it simple – download all as a shell script for NGINX based environments

Ubuntu 18.04.x Bionic Beaver:

sudo -s
wget https://raw.githubusercontent.com/criegerde/install-nextcloud/master/maintenance/ubuntu/upgrade-ubuntu.sh
chmod +x upgrade-ubuntu.sh && ./upgrade-ubuntu.sh

Debian 9.x Stretch:

sudo -s
wget https://raw.githubusercontent.com/criegerde/install-nextcloud/master/maintenance/debian/upgrade-debian.sh
chmod +x upgrade-debian.sh && ./upgrade-debian.sh

or perform the upgrade manually:

sudo -s
cd /var/www/nextcloud
/usr/sbin/service nginx stop

or on APACHE2 environments

sudo -s
cd /var/www/html/nextcloud
/usr/sbin/service apache2 stop

---

Start the update

sudo -u www-data php updater/updater.phar

Press y to start updating your Nextcloud and y again to continue

Now the code was updated. Press n to disable Nextclouds maintenance mode and the update has ben finished already.

You are on the latest Nextcloud release – it can be verifed by

sudo -u www-data php occ status
sudo -u www-data php occ -V

On NGINX environments modify Nextclouds .user.ini

sudo -u www-data sed -i "s/upload_max_filesize=.*/upload_max_filesize=10240M/" /var/www/nextcloud/.user.ini
sudo -u www-data sed -i "s/post_max_size=.*/post_max_size=10240M/" /var/www/nextcloud/.user.ini
sudo -u www-data sed -i "s/output_buffering=.*/output_buffering='Off'/" /var/www/nextcloud/.user.ini

or on Apache2 environments modify Nextclouds (.htaccess) as described here

php_value post_max_size 10240M

Verify all indices are properly set and everything ist up to date:

sudo -u www-data php occ db:add-missing-indices
sudo -u www-data php occ db:convert-filecache-bigint
sudo -u www-data php occ update:check

Restart both, PHP and NGINX

/usr/sbin/service php7.3-fpm restart
/usr/sbin/service nginx restart

or PHP and APACHE2

/usr/sbin/service php7.3-fpm restart
/usr/sbin/service apache2 restart

If app updates are found just issue

sudo -u www-data php occ app:update --all

or

sudo -u www-data php occ app:update <app-name>

sudo -u www-data php occ app:update contacts

Done!
