• apt install php-curl php-simplexml php-zip php-doctrine-dbal php-gd php-intl php-bcmath php-gmp php-imagick
• cd nextcloud
• sudo -u www-data /bin/bash
• ./php ./updater/updater.phar ### updates to nextcloud-13

• /etc/php.ini change post_max_size and upload_max_filesize to 100M, memory_limit to 600M, output_buffering to 0.

Self registration

• check that email notifications work
• go to nextcloud settings -> apps -> show disabled apps -> enable "registration"
• you will be bumped into the "upgrade" page, with luck there will be no errors
• adjust settings under "admin -> additional settings, at the very bottom"

To test registration:

• open browser that does not remember you (firefox)
• go to nextcloud, click on "register"
• enter email address, send the request, wait for reply email to arrive
• the reply email has a web link for completing account creation, go there
• select the new user name, new user password, say yes
• new account is created automatically, notice is sent to the owncloud administrators

There is no owncloud app for self registration "with approval". If somebody starts creating spam user accounts and filling them with evil contents shared the world, it is only possible to delete the badnicks after the fact.

php-8 update

• edit /etc/php/8.3/apache2/php.ini

• change opcache.interned_strings_buffer to 50, opcache.memory_consumption to 512
• systemctl restart apache2
