Can’t wait for the Nextcloud 16 update any longer?

Update to Nextcloud 16

Did you create a backup yet? Please be aware, some apps have to be re-activated manually afterwards.

Let’s begin the manual Nextcloud upgrade and stop all related services:

sudo -s
service nginx stop && service mysql stop && service redis-server stop && service php7.3-fpm stop

Move, download and extract the Nextcloud binaries:

mv /var/www/nextcloud/ /var/www/nc15
cd /usr/local/src
tar -xjf nextcloud-*.tar.bz2 -C /var/www && chown -R www-data:www-data /var/www/ && rm nextcloud-*.tar.bz2

Restore your previous config.php file and set the proper permissions:

cp /var/www/nc15/config/config.php /var/www/nextcloud/config/
chown -R www-data:www-data /var/www/nextcloud

Restart all services and optimize Nextcloud:

service mysql restart && service redis-server restart && service php7.3-fpm restart
sudo -u www-data php /var/www/nextcloud/occ db:add-missing-indices
sudo -u www-data php /var/www/nextcloud/occ db:convert-filecache-bigint
sed -i "s/upload_max_filesize=./upload_max_filesize=10240M/" /var/www/nextcloud/.user.ini
sed -i "s/post_max_size=./post_max_size=10240M/" /var/www/nextcloud/.user.ini
sed -i "s/output_buffering=.*/output_buffering='Off'/" /var/www/nextcloud/.user.ini
service nginx restart

Perform the upgrade itself:

sudo -u www-data php /var/www/nextcloud/occ upgrade
sudo -u www-data php /var/www/nextcloud/occ app:update --all

If the Nextcloud integrity check will fail please set the config.php value

'integrity.check.disabled' => true,

to true, then re-scan your files within your Nextcloud Admin-Panel and set the paramatere back to false again.

'integrity.check.disabled' => false,

Enjoy your personal data in your secured and hardened Nextcloud-Server!
