ownCloud 8.2.x (known issues, faq and upgrade problems)

Postby RealRancor » Sat Oct 31, 2015 11:12 am

Blogpost about upgrading: https://owncloud.org/blog/upgrading-to- ... erver-8-2/

General changes in this release: https://doc.owncloud.org/server/8.2/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!!!

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/8.2/adm ... -procedure

Updates between multiple major versions and downgrades are unsupported.

Please see: viewtopic.php?f=17&t=32087

Known Bugs

A list of bugs to fix or features to include for 8.2.6 is available here: https://github.com/owncloud/core/milest ... aintenance

Massive increase in MySQL-load: https://github.com/owncloud/core/issues/24651
fix will be included in 8.2.6: https://github.com/owncloud/core/pull/24841

Files locked: "server replied: Locked" or "Exception: <filename> is locked"
-> Was fixed with 8.2.2
-> If this still happens with existing files a manual cleanup of the locking table is needed
--> See https://github.com/owncloud/core/issues/21360 for more details

Known Issues with PHP 7

You need at least oC 8.2.3 for full PHP 7 compatibility. With PHP 7.0.6 there is small issue that will be fixed in OC 8.2.4:
viewtopic.php?t=36312
until this new release, you can apply this patch manually: https://github.com/owncloud/core/pull/24344

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>

with

<IfModule mod_php7.c>

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

Fixed Bugs

Shared folder (by link) doesn't display all files
-> Was partly fixed in 8.2.1 but happens again for two reasons:
--> PDF Viewer App might cause this
---> Report: https://github.com/owncloud/core/issues/21373
--> Internet Explorer (IE) still doesn't show all files
--->Report: https://github.com/owncloud/core/issues/21203
-> Fix for both issues is included in 8.2.3: https://github.com/owncloud/files_pdfviewer/pull/92
https://github.com/owncloud/core/pull/22548

E-Mail notifications not sent out
-> Might be caused by a deleted background job.
--> A possible workaround was posted here: https://github.com/owncloud/core/issues ... -166311215
--> The issue is also fixed with oC 8.2.3 and the update should re-add the background job automatically.

There are various incompatibilities with PHP7 known. Especially the shipped SabreDAV library 2.x in oC 8.2 is not compatible with PHP7. More resources:

https://github.com/owncloud/core/issues/21461 -> WebDAV issue
https://github.com/owncloud/core/issues/21309 -> Calendar/Contacts issue
https://github.com/owncloud/core/issues/21095 -> APCu issue (stripped page)
https://github.com/owncloud/core/issues/21352
https://github.com/owncloud/core/issues/21476

Until oC 9.0.0 or 8.2.3 is released which ships PHP7 compatible versions of SabreDAV it is recommended to stay at PHP 5.x.

Please only post known issues here (must be confirmed on github).

DO NOT post your individual problem during the update/upgrade process. Open a separate topic for that.

When upgrading to 8.2.2 you may get the error

Here is your backup: /var/derwentcloud/data/updater_backup/8.2.1.4-7d023030
Update failed.Unable to move /var/www/html/_oc-upgrade/8.2.2.2/core/resources to /var/www/html/resources

This is a known issue

viewtopic.php?f=36&t=31252 under “Fixed Bugs”
This is a user guide of how I resolved the issue; I am very new to Linux and OwnCloud so hopefully these steps will help people. I used SecureCRT to communicate with the server. All commands are in bold. Please take a backup of the server before running these steps.

I first had to locate the core.php file as mentioned in the bug fix.
https://github.com/owncloud/updater/pul ... diff=split

To do this I ran from the root directory
find –name “core.php”

from this I could see the file was located in
/var/www/html/apps/updater/lib/location/

Run the following commands
cd /var/www/html/apps/updater/lib/location/ - (change to the folder where core.php is located)
ls –l (list permissions on files)
sudo chmod 777 /var/www/html/apps/updater/lib/location/core.php - (changed the permissions to rwxrwxrwx)
nano core.php - (opens a text editor to edit the file)

change the line
$list = $fullList[‘8.1];
TO
$list = $fullList[‘8.2];
Overwrite the file and exit – I went back in to just double check the file had saved.

sudo chmod 644 /var/www/html/apps/updater/lib/location/core.php -(change the file permissions back to the previous permissions)

Run the upgrade from the OwnCloud Admin page.

Good Luck and i hope this helps and saves people a couple of hours
