[3.4.0.24][4.0.1.48] CalDav sync with Nextcloud server fails

Bug Reports
, ,
#1

REPRODUCIBILITY (% or how often): 100%
BUILD ID = OS VERSION (Settings > About product): 3.4.0.24, 4.0.1.48
HARDWARE (XA2, Xperia 10…): Xperia X (2x)
UI LANGUAGE: English UK
REGRESSION: (compared to previous public release: Yes, No, ?): Yes (compared to 3.1.x.x/3.2.x.x)

DESCRIPTION:

When adding an even either on the Nextcloud or on the phone side, the event is never synced to the other side. Creating the account itself is flakey - took me a lot of trying and re-trying to create the account in the first place (this was much easier in 3.1.x.x). Once created, it is not possible to “Update Calendars”.

PRECONDITIONS:

  • Xperia X freshly flashed with 4.0.1.48
  • Nextcloud 20 server, located in subdirectory on server
  • Freshly created, empty user account on the Nextcloud server
  • The CalDav account is configured as follows:
    • Server address: https://SERVER.DOMAIN/SUBDIRECTORY/
    • WebDAV path: /remote.php/dav/files/USER (only way to get the account created at all)
    • Calendar path: /SUBDIRECTORY/remote.php/dav/calendars/USER
      (Note: this was incorrect in the first version of the post)

STEPS TO REPRODUCE:

  1. Create a new event either in one of the synced calendars on the phone or directly on the Nextcloud server (web interface)
  2. Start a manual sync

Additional:
3) Create or delete a calendar on the Nextcloud server
4) Go to CalDav account and select “Update calendars”

EXPECTED RESULT:

For (1)/(2): event gets synced to the other side
For (3)/(4): new calendar shows up on phone, deleted calendars are deleted

ACTUAL RESULT:

For (1)/(2): events are not synced, logging shows errors.
For (3)/(4): calendars are not updated. “Update calendars” results in error message: “Server response did not provide user details for specified username”

ADDITIONAL INFORMATION:

  • This was originally seen with SailfishOS 3.4.0.24 on another Xperia X with the server still at Nextcloud 19. Syncing on that phone was working fine at least up until 3.1.x.x/3.2.x.x and I think it started failing with 3.3.x.x. Definitely fails with 3.4.0.24.
  • Syncing calendars with the Nextcloud 20 server works without issues with Thunderbird on a Linux desktop and with DavX5 under Android. Account creation in both cases works without issues (contrary to Sailfish). I did note that the Android DAV-app uses the /.well-known/caldav approach (which is configured correctly on the server) - Sailfish never seems to access that at all according to the server logs.
  • I did try to use a Nextcloud account instead of CalDav, but that’s even more difficult to set up and fails in pretty much the same way when syncing

(Edits: fixed wrong Calendar path, improved formatting)

Nextcloud failed to sync CardDAV
#2

Calendar path: /SUBDIRECTORY/remote.php/dav/files/USER

Thats the path to webdav (== files), not caldav. The resource is within /remote.php/caldav/calendars/$USERID/, but a working .well-known setup should take care of this.

#3

Well spotted, however, unfortunately, that was a mistake in copying it over into this posting - on the phone, the path is using calendars. My apologies for the confusion!

The .well-known set-up unfortunately never comes into play - according to my server logs, the Sailfish Phones never seem to access it (whereas Android DavX5 does), not even when I create the account.

Just a hint to make your OP more readable:
Sub list elements can be denoted using one * character only. And if you choose the cog wheel in the editor, you can select ‘hide details’ as a wrapper for your console log.

For comparison, here’s a log-excerpt from a sync attempt between the Android-phone (DavX5) and the same server:

What I notice is that the same type of PUT is used - and succeeds. To me, that looks as if something that the Sailfish phone does before the PUT is confusing the server, therefore causing the PUT to fail. When I look at the same log for Sailfish, I also notice that it starts with “PROPFIND / HTTP/1.1”, which looks strange to me, as the Nextcloud-server resides in SUBDIRECTORY.

#6

No progress here - I wonder whether anyone has CalDav working with Sailfish 4.0 and a Nextcloud server running in a subdirectory. @dcaliste - can I provide any additional information to help?

#7

Do you have the sync log from SailfishOS device ? See https://sailfishos.org/wiki/CalDAV_and_CardDAV_Community_Contributions to gather such logs.

Even better, could you create an account on such server for me ? Mind that this is a totally private initiative, I’m not working for Jolla. Send me a PM if you agree.

Yes is the answer to your question. I do. Mine runs as https://192.168.1.65/nextcloud and it works … but not without a lot of cursing from me when trying to make it work!

The way I’ve made it work is to specify the address as https://192.168.1.65/nextcloud/remote.php/dav/ and then in Advanced settings I specify the address path as /nextcloud/remote.php/dav/ and the Calendar path as /nextcloud/remote.php/dav/calendars/chris/

It may not be the correct way for the purists but it works for me

The synclog is included in the bug report above under “ADDITIONAL INFORMATION” -> " msyncd log from such an attempt". I’ll see what I can do about an account. Many thanks for your help! (I totally failed to realise that you do not work for Jolla :flushed:, which makes me appreciate your help all the more)

#10

Thanks for that - I’ll try that as well tonight! That was with a CalDav-account, not the Nextcloud-integration, right?

#11

My bad, I missed it somehow. I’m looking at it at the moment, but failed to notice anything obvious. I’ll do some further search on the Internet tomorrow to see why the PUT is failing. The PROPFIND are not important, they are some pocking to get the calendar paths, which is failing at the moment, but such kind of failure are ignored by the sync plugin. I’m not encline to think that they could put the server in a way that would make the PUT fails, while it would not without the initial PROPFIND poking.

That’s for the Nextcloud Account as listed under Accounts -> Advanced settings -> Calendar path.

For completeness, this is how I’ve setup all the others for Nextcloud :-
WebDAV path is /nextcloud/remote.php/dav/files/chris
Address book is /nextcloud/remote.php/dav/
Images is /nextcloud/remote.php/dav/files/chris/Photos
Backup path is /nextcloud/remote.php/dav/files/chris/Sailfish OS/Backups but that fails each month when I ask it to do a backup so I do it to Dropbox instead.

I didn’t see any point in creating a CalDAV and CardDAV account if I could make the Nextcloud system work properly.

Now if only we had Avahi running on Sailfish I wouldn’t need to specify the IP address and could instead use ubuntuoc.local which everything else, including my iPhone, can connect to.

Thanks!

The main reason I used that approach was that I have read about the issues of the Nextcloud-integration with subdirectories - and even after searching, it was still not clear to me whether that had been resolved by Jolla or not. The CalDav-integration was working, at least up until 3.2, so I went with that first. If there is any chance to get the Nextcould-integration working instead, that would of course be a bonus.

#14

The server is replying with an error 503 on the PUT, which corresponds to a server error (as far as I know). I’m wondering if the sent data are responsible…

Could you try to send PUT requests with curl ? Something like:

  • curl -X PUT -u login:password -F "Content-Type : text/calendar; charset=utf-8" -F "file=@plop.ics" http://example.com/SUBDIRECTORY/remote.php/dav/calendars/USER/reminders/, changing of course your login and password, the destination URL and the name of the file used to store the data.

Can you try with these two sets of data:

Notice that to be compliant, the file should be saved with DOS end of lines.

I’ve changed the way the timezone is exposed some versions ago because the implementation in OpenXchange server was having issues with the former version. Maybe it is raising an issue with Nextcloud ?

<d:error xmlns:d=“DAV:” xmlns:s=“http://sabredav.org/ns”>
<s:exception>Sabre\DAV\Exception\Conflict</s:exception>
<s:message>PUT is not allowed on non-files.</s:message>
</d:error>

I’ve also tried curl -X PUT -u login:password -F "Content-Type : text/calendar; charset=utf-8" -F "file=@plop.ics" http://example.com/SUBDIRECTORY/remote.php/dav/calendars/USER/reminders/plop.ics
but that resulted in

<?xml version="1.0" encoding="utf-8"?>

<d:error xmlns:d=“DAV:” xmlns:s=“http://sabredav.org/ns”>
<s:exception>Sabre\DAV\Exception\UnsupportedMediaType</s:exception>
<s:message>This resource only supports valid iCalendar 2.0 data. Parse error: This parser only supports VCARD and VCALENDAR files</s:message>
</d:error>
To make certain that this was not due to me messing up the file while copying from the forum, I also tried the same with an appointment that I had previously downloaded from the same Nextcloud calendar, but same result.

I tried this approach as well, while only enabling calendars and setting the paths as you described. Unfortunately, that also failed with “Could not create account. Check sign-in details and try again. Authentication failed for URL: https://SERVER//SUBDIRECTORY/remote.php/dav/ocs/v2.php/cloud/user”. On the server, I get this in the log:
default nnn.nnn.nnn.nnn - - [18/Mar/2021:22:17:35 +0100] "GET /SUBDIRECTORY/remote.php/dav/ocs/v2.php/cloud/user HTTP/1.1" 404 0 "" "Mozilla/5.0"
Normally, the ocs directory is at the root of SUBDIRECTORY - are you using any rewrites with regard to ocs?

Sorry, my curl-foo is really bad. I didn’t try it actually with my own caldav provider to see if it was working, but rely on Internet suggestions. My bad. Spending a bit more time this morning on trials and errors with mailbox.org, here is a command that works for it and may work for Nextcloud servers :
curl -i -u LOGIN:PASSWORD -T plop.ics https://example.com/SUBDIRECTORY/remote.php/dav/calendars/USER/reminders/

Hopefully we can sort all this out. Let’s try.

The directory structure for my setup looks like this - /var/www/html/nextcloud/ocs/ so no, I’m not.

This one works - for both versions of the ICS file you posted earlier (though I put one in a new calendar due to ID conflict). So, that does not seem to explain the 503 I get when trying to sync with the phone. I also dove into the nextcloud.log once more in the hope of finding some entries that correspond to the 503s in the web server log from the failed sync attempts, but no such luck, unfortunately.
