ownCloud 9.0.x (known issues, faq and upgrade problems)

Blogpost about upgrading: https://owncloud.org/blog/time-to-upgra ... cloud-9-0/

General changes in this release: https://doc.owncloud.org/server/9.0/adm ... notes.html

Another blogpost how to do a correct upgrade: http://blog.jospoortvliet.com/2016/01/h ... -skip.html

Please read those links carefully!!!

Calendar and contacts in 9.0

The Calendar and Contacts apps have been rewritten and the CalDAV and CardDAV backends of these apps were merged into ownCloud core. During the upgrade existing Calendars and Addressbooks are automatically migrated. As a fallback for failed upgrades or an option to test a migration dav:migrate-calendars and/or dav:migrate-addressbooks scripts are available via the occ command after you have added 'debug' => true to your config/config.php. See https://doc.owncloud.org/server/9.0/adm ... mmand.html how to run occ.

Migration of CalDAV and CardDAV should be done automatically,you can check if everything run perfectly and re-initiate the migration process:

Browser support in Calendar (and probably also contacts) App
-> Only Chrome, Firefox and Safari are supported. No IE/EDGE

There were problems with the code integrity check. More information…

ownCloud 9 has introduced a code signing and integrity check feature to help you identify modified and corrupted files. If you're getting the mentioned error please see:

https://doc.owncloud.org/server/9.0/adm ... y-messages

More info about code signing are available here: https://owncloud.org/blog/code-signing-in-owncloud-9-0/

If you get this message because you have modified your .htaccess and/or .user.ini (e.g. to raise the upload limits) the upcoming 9.0.1 will include a workaround for this:

Common issues

On every major upgrade it is recommended to do a full upgrade by deleting all files and folders within your installation directory except /data/ and /config/ and then extract the new code into this installation directory. How to do a full upgrade can be found at the documentation:

https://doc.owncloud.org/server/9.0/adm ... -procedure

Updates between multiple major versions and downgrades are unsupported.

Solved other issues

When running Apache and PHP there is currently also an issue within the .htaccess shipped by oC. Make sure that you replace:

<IfModule mod_php5.c>


<IfModule mod_php7.c>

in your .htaccess. Ref: https://github.com/owncloud/core/issues/21146

PHP7 on openSUSE
A few people (but not all) have bumped into issues with PHP 7 on openSUSE 13.2 after upgrading, perhaps hold off a bit on your update until these are resolved. There's a temporary fix here.

It seems upgrading on Debian can get you in trouble: due to a interaction between packaging and core, a rewrite rule breaks the ownCloud installation. As a workaround one can add RewriteBase /owncloud after RewriteEngine on in .htaccess or disable mod_rewrite like this:

Code: Select all

a2dismod rewrite

Code: Select all

/etc/init.d/apache2 restart
Find more info here.

Update fails because SQL table already exists

Postby eldrich » Sun Mar 13, 2016 2:03 pm

The main reason I am posting this is in case someone else has this problem and wants to see a possible solution.

Steps to reproduce
1. sudo -u apache ./occ upgrade

Expected behaviour
Upgrade should complete

Actual behaviour
Upgrade fails with mysql (mariadb) error:
SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'oc_notifications' already exists

Server configuration
Operating system: Centos 7.2
Web server: Apache 2.4
Database: Mariadb 5.5.44
PHP version: 5.4
ownCloud version (see ownCloud admin page): ->> 9.0
Updated from an older ownCloud or fresh install: Updated, originally was an 8.0 sqlite system but updated to mariadb and owncloud 8.2

Essentially running the occ upgrade fails because the oc_notifications table already exists,
Simple solution is to use mysql command to drop that table (verified it was empty first)

%> mysql -u XXX -p
mysql> use owncloud;
mysql> drop table oc_notifications;
mysql> quit;

then rerun the ./occ upgrade and it completes.
I wonder if the failure is because the DB was originally an sqlite one that was upgraded to MySQL?

Hi all,

I faced some trouble to access my owncloud page after upgrading from 9.02 to 9.03. Let me share my case and how I solved it. This might help our community.

In short, I was unable to access my owncloud page from browsers after the upgrade. A 404 (not found) or 403 (file permissions denied for /owncloud or /app/file directories) error. I changed a line in .htaccess file to solve it.

Details to reproduce the error:

After upgrading from yum, I restarded my server. At this point I was able to access owncloud page, but it was set on maintenance mode. I went back to terminal and went on with the upgrade:

Code: Select all

sudo -u apache php /var/www/html/owncloud/occ maintenance:mode --off
sudo -u apache php /var/www/html/owncloud/occ upgrade
systemctl restart httpd

I also changed file permissions as defined in the Admin document.

After these, I was unable to access my owncloud page and got a 404 error.

On Apache log, I had the following error:

Code: Select all

[Sat Jul 09 12:27:58.390298 2016] [autoindex:error] [pid 1500] [client] AH01276: Cannot serve directory /var/www/html/owncloud/: No matching DirectoryIndex (none) found, and server-generated directory index forbidden by Options directive

To solve this,

I changed the .htaccess file as follows:

Code: Select all

vi +96 /var/www/html/owncloud/.htaccess


Code: Select all

RewriteBase /


Code: Select all

RewriteBase /owncloud

Restarted httpd and that's it.

thanks for sharing. If your RewriteBase is wrong then make sure that you have configured this options correctly in your config.php:

Thanks for commenting. Reading your link helped clearing my mind.

Well, I'd read this page on your link before and also had changed config.php file as described. But these haven't fixed anything. Only when I changed the .htaccess file my problems went away.

Just to give a bit more information, I installed ownCloud with its default settings meaning I access my ownCloud page with "/owncloud" at the end of my domain name. I think it would be nice to have "/owncloud" configured in .htaccess and config.php files. This would reflect a default installation.

This occ maintenance:update:htaccess command will be very welcome. It's a great idea.
