Problem updating 8.2.10 -> 8.2.11

I am trying to update owncloud from version 8.2.10 to 8.2.11. I am using the update-plug-in of owncloud. The back up works, but then I get the error message:
“/www/htdocs/…/…/html/owncloud/data/updater_backup/8.2.11.zip extraction error”
And my provider (all-inkl.com) support says that there is the message:
“pcfg_openfile: unable to check htaccess file, ensure it is readable”
In addition, the support says that the access permissions of </www/htdocs/…/…/html/owncloud/data> seem to be the problem. chmod of is set to 0777.

Any help appreciated!

Addendum:
Error mesage in the owncloud administration area:
Error PHP Automatically populating $HTTP_RAW_POST_DATA is deprecated and will be removed in a future version. To avoid this warning set 'always_populate_raw_post_data' to '-1' in php.ini and use the php://input stream instead. at Unknown#0

Changing chmod of < …owncloud/data> did not solve the problem.

I have downloaded the owncloud-8.2.11.zip from http://ftp.icm.edu.pl/packages/owncloud/ and copied this zip-file into the <…/ownloud/data/updater_backup> directory. Then the update process worked. Owncloud is accessible now without any problem (as far as I see). But how to avoid this effort in the future? Version 9 of owncloud is waiting for installation!

Hi,

if you have a backup, you could just remove ownCloud 8.2 entirely and install 10.0.6 fresh and import your backup

I have solved the problem. After coying the owncloud-8.2.11.zip-file into the backup_updater directory update worked. Then the other updates up to version 10 showed no problem.
The problem was - as far as I see it - the fact, that version 8.2.11 was not available an y more in the download area of owncloud community.
Thank You very much!

I have the very same problem. Where did you get the 8.2.11.zip file? Thanks.

Hi, I would recommend using this method:
