Expose subscribed webcal calendars via CalDAV

[grafenhofer]

The calendar app has recently gained support for subscribing to third party webcal calendars (see owncloud/calendar#132). It would be great to expose these imported calendars via CalDAV (e.g. to mobile clients). Nextcloud would act as a kind of proxy service. One usecase is increased privacy for (mobile) users (only the Nextcloud server connection gets exposed to the original webcal provider).

See also my new commentary on owncloud/calendar#751. This appears already to work using CalDAV-Sync, but not other clients. It would be interesting to find out why.

Comment from owncloud/calendar#751 (comment)

This is an issue that you need to bring on the clients that you use.

Very well, @RealRancor. In that case, completely disregard everything I said and treat it as a feature request. I'll delete all my comments tomorrow.

@Pazu As it seems its not clear to you what that comment means:

I think @tcitworld tried to say there that you should contact the author of your used android/ios app and report a bug to them that they seems to have an issue in their app.

[Pazu]

@RealRancor: the Android app exposes subscribed calendars via CalDAV, which is what we want. Whether or not the client is doing something right or something wrong is unknown to me.

Apple's Calendar application doesn't expose subscribed calendars via CalDAV. Whether or not it's doing something right or wrong is unknown to me.

I will not contact Apple and report this behavior as a bug.

I'll delete my comments tomorrow.

Thats why you get the info like the posted comment above where the issue is coming from.

I'll delete my comments tomorrow.

No need to delete comments.

I think I solved this. In Apple's Calendar application, I needed to update the server path from the old style to the new (that is, the one currently shown by ownCloud 9.1.2 as the "iOS/OS X CalDAV address"; e.g., "https://example.com/remote.php/dav/principals/users/USERNAME/"), and the subscribed calendars suddenly appeared.

[martinlanger90]

In DAVDroid they're not shown anyway.
But this should be DAVDroid bug then? Am I right?
Thanks

@martinlanger90 With which exact URL style did you add the ownCloud account to DAVDroid?

(With CalDAV-Sync, for example, it's only necessary to use the minimal 'https://example.com/' style and it seems to find the correct DAV point.)

[martinlanger90]

Yep. Tried with minimal url and tried with your extended one above my post. Both don't show up the subscribed calendars. Maybe I can collect a log from DAVDroid. But I've to figure out how to take logs with DAVDroid first. And yes with CalDAV-Sync it works. But unfortunately not with DAVDroid which could sync contacts as well.... Thank you anyway

There is a longer FAQ available here explaining the needed steps: https://davdroid.bitfire.at/faq/entry/how-to-debug/

[martinlanger90]

Got some information on that already. So it seems, DAVDroid can't handle this, until the subscriptions aren't exposed via CalDAV.

The https://example.com/remote.php/dav/principals/users/USERNAME/ format URL doesn't work on Evolution to show subscribed calendars, just the local ones.

Hi! do you have any news at this topic? to publish all subscribed calendars over caldav would be very awesome, because with this feature it would be possible to easily centralize a next part of my daily life into nexcloud! 👍

[Pazu]

The news is that it works if you use the correct CalDAV URL, but not with some CalDAV clients, notably DAVDroid.

@samweisgamdschie If you're running nextcloud you're mostly wrong in this issue tracker. Try it in the nextcloud issue tracker if you want news for nextcloud on this topic.

It doesn't really seem appropriate that an issue is closed because it is waiting for activity from the owncloud team but then the owncloud team doesn't take any action and instead just closes the issue.

Feel free to reopen this issue if you deem it appropriate.

I don't seem to have any ability to do that.
