OwnCloud
ownCloud is an open source cloud software suite for remote access of calendar, address and file data. It uses a SabreDAV backend.
As of 2012-02-25 there are a number of known issues (bugs) in the SabreDAV version used by ownCloud. Please try to update the SabreDAV part of your ownCloud installation first if something doesn't work as expected. Most users reported success with SabreDAV version 1.5.8. SabreDAV version 1.6 has been reported "not working" with ownCloud 3. All known issues have been fixed in ownCloud 4. There is a new CalDAV issue with ownCloud 4, see below

Setup with ownCloud 4 & ownCloud 5
In ownCloud 4 the CalDAV and CardDAV path names changed, once again. If you upgrade to ownCloud 4 you'll have to recreate the accounts in Android. You can find the correct CalDAV/CardDAV path names in settings -> personal. The path names below are just examples, please refer to your actual settings.
CalDAV-Sync
- Server URL: <servername>/owncloud/remote.php/caldav/ (see Calendar in settings -> personal in your ownCloud account)
- Use SSL: check accordingly
- Username: your login name
- Password: your password
CardDAV-Sync
- Server URL: <servername>/owncloud/remote.php/carddav/ (see Contacts in settings -> personal in your ownCloud account)
- Use SSL: check accordingly
- Username: your login name
- Password: your password
Setup with ownCloud 3
CalDAV-Sync
- Server URL: <servername>/owncloud/apps/calendar/caldav.php/calendars/
- Use SSL: check accordingly
- Username: your login name
- Password: your password
Note: The /owncloud/ part depends on your setup. If it doesn't work try /cloud/ (or whatever your ownCloud root is) instead.
CardDAV-Sync
- Server URL: <servername>/owncloud/apps/contacts/carddav.php/addressbooks/
- Use SSL: check accordingly
- Username: your login name
- Password: your password
Note: The /owncloud/ part depends on your setup. If it doesn't work try /cloud/ (or whatever your ownCloud root is) instead.
known issues
CalDAV
There is a known bug in SabreDAV (which is used by ownCloud): If your calendar contains events with certain time zone IDs that are not recognized by SabreDAV then the server returns an "internal server error" instead of a proper response to the calendar query. Currently your only option is to find those events and delete them (or change the time zone id). Please note that many desktop clients like Thunderbird Lightning and Evolution do not use "calendar query" and thus still work with ownCloud in that case. Please see [1] there is a patch linked that is reported to fix this issue. This has been fixed in ownCloud 4.
If some recurring events are missing on your phone see: [2]. Alternatively update SabreDAV in your ownCloud installation to the most recent SabreDAV release. This has been fixed in ownCloud 4 (it uses a more recent SabreDAV release).
- ownCloud 4
- There is a new issue with ownCloud 4. Please see TRIGGER:PT0S throws exception It's actually a bug in the SabreDAV version used by ownCloud 4. One of the comments contains a fix.
Syncing with ownCloud 4.0.4 seem to be completely broken. I got several reports of issues like this one: http://mail.kde.org/pipermail/owncloud/2012-July/004263.html here are the bug reports that seem to cover this issue oc-1199 and oc1247.
CardDAV
The contact editor in ownCloud is broken and creates inconsistent vCards if you're not using the structured name editor. The regular editor doesn't update the N
field in the vCard. To workaround this issue, please use the structured name editor, by clicking on the pen icon next to the name field.
Troubleshooting
Can't create account in CardDAV-Sync and/or CalDAV-Sync won't sync
CardDAV-Sync and CardDAV-Sync verify the DAV headers sent by the server to ensure the server actually supports CardDAV/CalDAV. If you get the message "This URL seems not to point to a (supported) CardDAV server or you don't have access to it." or CalDAV-Sync doesn't sync, please check if you've enabled the Google pagespeed module. The pagespeed module removes the DAV headers.
At present the only known way to "fix" that is by disabling the pagespeed module. To do so, add this line to your virtual host or your global Apache config.
ModPagespeed off
Alternatively you can completely deactivate the module by running this command:
a2dismod pagespeed
A better way to resolve this issue is to disable the pagespeed module for CalDAV and CardDAV only. A user reported that adding the following lines to the .htaccess
file in the ownCloud root directory works (thanks Michael):
ModPagespeedDisallow "http://*exampleserver.com/owncloud/remote.php/*" ModPagespeedDisallow "https://*exampleserver.com/owncloud/remote.php/*"
Of course you'll have to adjust the URL to your setup.
Server issues
If you're getting server errors, the reason is (as the name says) located on the server. This sections aims to give you hints what to do for some known issues.
Error Code 500
This error usually means the server just crashed during preparing the response. In some cases it helps to enable the option entire calendar for regular syncs in the account settings. That will disable filtering the results by time range at the expense of higher traffic during sync. If that doesn't fix it try to enable Use WebDAV sync method (some translations still call this option Synology Workaround).
Request was calendar query
> Während der Synchronisation mit user@server.com hat der Server > mit dem Status Code 500 geantwortet. Die Anfrage war calendar-query. >Der Inhalt der Antwort war:
This is a known bug in the SabreDAV-backend (http://owncloud.10557.n7.nabble.com/Errors-while-syncing-shared-calendar-tt13186.html#none). It'll be fixed in the upcoming release: https://github.com/owncloud/calendar/commit/ca006528552054a5a9f39ca7909e87f4aedd1f5d
Temporary files directory not accessible
Error Message:
Notice: session_start() [function.session-start]: ps_files_cleanup_dir: opendir(/tmp) failed: Permission denied (13) in /www/htdocs/w00xxxxxx/owncloud;/lib/base.php on line 264 Sabre_DAV_Exception_NotAuthenticated No basic authentication headers were found 1.6.4
Explanation:
This happens when your hosted ownCloud has no access to the global /tmp directory.
Fix:
To fix it you have to change the temporary directory of your installation. Create a new directory and change the variable session.save_path
to point there (i.e. change .htaccess to contain the following line, change the path accordingly)
php_value session.save_path /www/htdocs/w00xxxxxx/temp/Don't forget to create that directory if it doesn't exist yet.
Trigger parsing error
Error Message:
Exception DateInterval::__construct(): Unknown or bad format (P) 1.6.2
Explanation:
That's caused by a bug in SabreDAV.
Fix:
Upgrade SabreDAV to the latest 1.6.x release or use the fix mentioned here: TRIGGER:PT0S throws exception
Time zone issue
Error Message:
Exception DateTimeZone::__construct(): Unknown or bad timezone (GMT+01.00/+02.00) 1.5.7
Explanation:
That's caused by a bug in the SabreDAV release used by ownCloud 3.x. It's not able to handle non-Olson time zone ids properly.
Fix:
Upgrade SabreDAV to the latest 1.5.x release or upgrade to ownCloud 4.x.
Upload issues
Error Message:
java.lang.Exception: could not upload new resource
Server log contains something like:
PHP Fatal error: Call to undefined function iconv() in /var/www/htdocs/owncloud/apps/contacts/lib/vcard.php on line 200
Explanation:
iconv.so
is not enabled in your php.ini.
Fix:
Enable iconv.so
in your php.ini.
Sync error on IIS webserver
(owncloud 5 on IIS 8)
Error Message:
405 - HTTP verb used to access this page is not allowed.
Explanation:
For CalDAV/CardDAV/WebDAV it is necessary to allow the HTTP methods (verbs) PROPFIND and REPORT on the server. Also, there seem to be inteferences between the WebDAV functionality of IIS itself and owncloud.
Fix:
Uninstall WebDAV functionality, deactivating is not sufficient. Then allow all HTTP request methods to the FastCGI handler.
SPDY & mod_pagespeed
According to a user report these might cause issues when enabled. If you're having sync issues without a distinct error message check if these two modules are enabled on your server and try to sync again without them.
Authentication issue with Owncloud 8
Apparently there was a new regression in Owncloud 8. See here for the details and a fix: https://github.com/owncloud/core/pull/14275
