Nextcloud version (eg, 29.0.5): 29.0.2
Operating system and version (eg, Ubuntu 29.04): Ubuntu 22.04.4
Apache or nginx version (eg, Apache 2.4.25): Nginx 1.18.0
PHP version (eg, 8.3): 8.2.20
The issue you are facing:
Trying to upgrade from 29.0.2 to 29.0.3 fails with a crash of occ upgrade and Nextcloud is not usable afterwards.
Is this the first time you’ve seen this error? (Y/N): N
I first tried the update via the web Updater, restored my backup after the failure and tried the same from CLI. There was no error shown in the web updater until maintenance mode was disabled and it returned to the main web page. Only with the CLI updater I then saw the below stacktrace.
Steps to replicate it:
- sudo -u www-data php /var/www/nextcloud/updater/updater.phar
- Start update? [y/N] y
- Should the “occ upgrade” command be executed? [Y/n] y
CLI output of the occ upgrade:
An unhandled exception has been thrown:
InvalidArgumentException: app cannot be an empty string in /var/www/nextcloud/lib/private/AppConfig.php:1189
