Nextcloud AIO update from NC30 to NC31 failed

[Matthias_Grabner]

The Basics

• Nextcloud Server version (e.g., 29.x.x):
  • 31.0.7 (upgraded from 30.0.0.14)
• Operating system and version (e.g., Ubuntu 24.04):
  • Ubuntu 24.04
• Web server and version (e.g, Apache 2.4.25):
  • Apache 2.4.63
• Reverse proxy and version (e.g. nginx 1.27.2):
  • nginx openresty/1.27.1.2
• PHP version (e.g, 8.3):
  • 8.3.23
• Is this the first time you’ve seen this error? (Yes / No):
  • Yes
• When did this problem seem to first start?
  • After upgrading to AIO 11.4.0
• Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
  • AIO (11.4.0)
• Are you using CloudfIare, mod_security, or similar? (Yes / No)
  • No

Summary of the issue you are facing:

I am seeing a white screen when trying to open Nextcloud. This occurred after upgrading the first time in a longer time (from nc 30.0.0.14). After upgrading, the containers did not start and logs revealed:

Please restore from backup and try again! If you do not have a backup in place, you can simply delete the update.failed file in the datadir which will allow the container to start again.

I deleted the update.failed file and after the second try, the container started successfully. However, I now receive a white screen. The logs point to the following error:

PHP Fatal error: Declaration of OC\Core\Command\Base::run(Symfony\Component\Console\Input\InputInterface $input, Symfony\Component\Console\Output\OutputInterface $output) must be compatible with Symfony\Component\Console\Command\Command::run(Symfony\Component\Console\Input\InputInterface $input, Symfony\Component\Console\Output\OutputInterface $output): int in /var/www/html/core/Command/Base.php on line 152

Even though I upgraded after a long time, I don’t think this is applicable, as the PHP version seems to be high enough?

Unfortunately, I do not know the AIO version I upgraded from and do not have a backup I could restore.

Any help in getting my instance up and running again would be greatly appreciated!

Configuration

Nextcloud

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

EDIT: Found the old NC version I was using and added it to the post.
