[details=“Support into”]
Nexcloud version 25.0.3
Opertaing system Ubuntu 20.04
Apache 2.4.41
PHP 7.4, 8.1, 8.2 ← Yes, really.

I am attempting to migrate to a new server. The existing install uses PHP 7.4. The new install requires PHP >8.0. I have 8.1 and 8.2 installed. I have copied over my data folder and database.

Following the manual install guide, when I enter the nextcloud directory for the latest version, I switch to either PHP 8.1 or 8.2. It doesn’t matter. Running “php occ” results in an error:

php occ
An unhandled exception has been thrown:
Error: Class “Symfony\Component\HttpFoundation\IpUtils” not found in /var/www/html/nextcloud/lib/private/AppFramework/Http/Request.php:574

#4 /var/www/html/nextcloud/console.php(48): require_once(‘…’)
#5 /var/www/html/nextcloud/occ(11): require_once(‘…’)
#6 {main}

I do not get this error in under nextcloud.old using PHP 7.4. I have searched for a helpful reference but I am stuck. What is missing?

Any help is appreciated. Thank you.

Progress sort of. Composer installed the symfony requirements, but now I have something else:

An unhandled exception has been thrown:

I started again and copied apps over one at a time but with a script and now it works.
