ownCloud update problem (via UI)

[mmattel]

Server: Ubuntu 14.04, PHP 5.5.9, MySQL, Redis
Browser: W7/Opera

One of my productive instances running 8.2.0 reported that there is an update to 8.2.2 available.

I went to the admin page to the bottom and tried to update (stable).
I got the following response:

The following Files and Directories (a loooong list) has been reported:

The web directory name for owncloud

/var/www/<directory>

Directories

3rdparty
core
lib
l10n
settings
ocs
ocs-provider
resources

Files in Root

.htaccess
.mailmap
.tag
.user.ini
AUTHORS
COPYING-AGPL
console.php
cron.php
db_structure.xml
index.html
index.php
indie.json
occ
ocs-provider
ocs-provider/index.php
ocs-provider/provider.php
public.php
remote.php
robots.txt
status.php
version.php

This is the complete instance!

If I compare the requirement to set proper access rights according the documentation (https://github.com/owncloud/documentation/blob/master/admin_manual/installation/installation_wizard.rst#setting-strong-directory-permissions) and the required rights as listed above to do the update, I see a big difference. Which is also a security issue because some files need root:[HTTP group] and not [HTTP group]:[HTTP group]

Finally it ended after a couple of tries (no more access rights complaints) with:

Update fehlgeschlagen.Unable to move /<directory>/_oc-upgrade/8.2.2.2/core/resources to /<directory>/resources

Following updater backups have been created so far:

owncloud.log:

Error   updater Unable to move /<directory>/_oc-upgrade/8.2.2.2/core/resources to /<directory>/resources    2016-01-14T15:03:43+01:00
Error   updater Something went wrong for core. Rolling back.    2016-01-14T15:03:17+01:00
Error   PHP rename(/<directory>/_oc-upgrade/8.2.2.2/core/resources,/<directory>/resources): File exists at <directory>/apps/updater/lib/helper.php#52   

<directory> ... owncloud instance

How to deal with that?

@mmattel You need to revert the strong permissions as described in the documentation before being able to using the updater app:

https://doc.owncloud.org/server/8.2/admin_manual/maintenance/update.html#setting-strong-permissions

The Unable to move /<directory>/_oc-upgrade/8.2.2.2/core/resources to /<directory>/resources was a bug in the updater previous to 8.2.2: owncloud/updater#189
