Upgrading to v.10.0 kills APCu

I just discovered the magic of APCu on my ownCloud servers; I've configured it on both test and production, and it's working great.

Upgrading to V.10 kills that, on my test server. Despite nothing else changing (except the install of v.10 from the repository), I get the error that there's no memcaching configured.

Has anyone had any issues with this, following an upgrade?

This is on Ubuntu 16.04, PHP7, Apache, and a Previously fully functional version of OC 9.1.4.

Hey @evo5150 thank you for reporting this.

Could you please provide the developers a filled out issue template on https://github.com/owncloud/core/issues/new

Please also specify your apcu configuration.

Steps to reproduce

  1. Installed APCu on 9.1.4, and configured config.php. Works fine.
  2. Installed v.10.0 from repositories; then get error in Admin page that no caching configured
  3. revert virtual machine snapshot back to 9.1.4, and it is working again

Expected behaviour

APCu caching should work

Actual behaviour

APCu caching in v.10.0 doesn't work

Server configuration

Operating system: Ubuntu Server 16.04LTS

Web server: Apache

Database: MySQL

PHP version: 7.0

ownCloud version: (see ownCloud admin page) v.10.0

Updated from an older ownCloud or fresh install: update from 9.1.4

Where did you install ownCloud from: Repositories located on SuSe

Signing status (ownCloud 9.0 and above):

Login as admin user into your ownCloud and access 
paste the results into https://gist.github.com/ and puth the link here.

The content of config/config.php:

Log in to the web-UI with an administrator account and click on
'admin' -> 'Generate Config Report' -> 'Download ownCloud config report'
This report includes the config.php settings, the list of activated apps
and other details in a well sanitized form.


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

*ATTENTION:* Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.
If done manually then it is critical for your own privacy to dilligently
remove *all* host names, passwords, usernames, salts and other credentials before posting.
You should assume that attackers find such information and will use them against your systems.

List of activated apps:

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

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


Are you using encryption: yes/no


I filled it out the best I could; some of it wouldn't have been helpful, since I've reverted back to v.9.1.4.

Please create a new issue at https://github.com/owncloud/core/issues/new instead.
