Version upgrade problem

[nemo87]

I would like to upgrade the version from 25 to 26, I installed php 8,

pi@raspberrypi:~ $ php -v

PHP 8.4.7 (cli) (built: May 9 2025 07:01:24) (NTS)

Copyright (c) The PHP Group

Zend Engine v4.4.7, Copyright (c) Zend Technologies

with Zend OPcache v8.4.7, Copyright (c), by Zend Technologies

and then downloaded the new version, copied the folder to /var/www and gave the command:

pi@raspberrypi:/var/www/nextcloud $ sudo -u www-data php updater/updater.phar

Nextcloud Updater - version: v26.0.6-13-gef27ae9 dirty

Current version is 26.0.13.

PHP Fatal error: Uncaught Error: Call to undefined function NC\Updater\curl_init() in phar:///var/www/nextcloud/updater/updater.phar/lib/Updater.php:472

Could you help me?

hi @nemo87 the first version supporting php84 is nc31 so I would recommend you revert to a supported php version and perform upgrades one step at time to at least NC30 (oldest maintained version for now)

For Nextcloud 25 you must use PHP 8.1 or lower.

Requirements Nextcloud 25
Requirements Nextcloud 26
Requirements Nextcloud 27
Requirements Nextcloud 28
Requirements Nextcloud 29
Requirements Nextcloud 30
Requirements Nextcloud 31

Maybe you can upgrade from Nextcloud 25 to Nextcloud 31 only with PHP 8.1 see the first and last link. With Nextcloud 31 you can change to PHP 8.4
