Broken instance after Update

[stefan-niedermann]

Steps to reproduce

1. Install Nextcloud 12.0.1
2. Use Updater App to update to 12.0.2

Expected behaviour

After all checkmarks are done there are two buttons for maintenance mode. Clicking "deactivate maintenance mode" should initialize the update and show blue cloudy screen

Actual behaviour

page stays empty (completely white), server responds with HTTP 500

Server configuration

Operating system: Debian

Web server: Apache 2.x

Database: MySQL 5

PHP version: 5.6.31

Nextcloud version: former 12.0.1, now hopefully 12.0.2

Updated from an older Nextcloud/ownCloud or fresh install: updated

Where did you install Nextcloud from: updater app

Signing status:

Signing status

Login as admin user into your Nextcloud and access 
http://example.com/index.php/settings/integrity/failed 
paste the results here.

List of activated apps:

Sorry, no access.

App list

If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your Nextcloud installation folder

Nextcloud configuration:

Config report

If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your Nextcloud installation folder

or 

Insert your config.php content here. 
Make sure to remove all sensitive content such as passwords. (e.g. database password, passwordsalt, secret, smtp password, …)

Are you using external storage, if yes which one: local/smb/sftp/...

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/...

LDAP configuration (delete this part if not used)

LDAP config

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your Nextcloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';


Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

Can i savely replace the files with the backup-files created by updater app during the update-process?

Can i savely replace the files with the backup-files created by updater app during the update-process?

Yes. But as always: keep your config and data dir untouched ;)

In the provided logs nothing useful can be found.

What is in the updater.log in the data dir?

[stefan-niedermann]

i'll check. in the meantime i installed the backed up version (worked good)

As there is no feedback on this one here I will close it for now. If there is more, we could reopen this ticket.
