files_sharing app required as dependency

[gbcreation]

I want to share my calendar with other users of my Nextcloud server. When I click on the Share Calendar icon/button near the name of my calendar in the left panel, nothing happens. I tried with Firefox 55, and Chromium 61 (also with the --disable-extensions to ensure there is no extension conflicting with the calendar sharing feature).

Steps to reproduce

1. Just click on the Share Calendar button/icon near the name of a calendar

Expected behaviour

It should display some options to configure the calendar sharing.

Actual behaviour

No options displayed. Nothing happens.

Is the Sharing feature activated in the Nextcloud administration section ? Do you have an adblocker ?

[gbcreation]

Here is my configuration in the Nextcloud administration section:

Using the settings above, nothing appears when I click on the Share Calendar button/icon near the name of my calendar in the Calendar app.

If I enable Allow users to share via link, and i click on the Share Calendar icon/button near the name of my calendar, there is only a Share link checkbox that appears. When I check this box, there is only a Public access label that appears like this:

But this is not what I want. I don't want to share my calendar using a public link. I would like to share it only to other users of my Nextcloud server, and configure the rights they could have (can share, can edit, etc). Something similar to this screenshot shown in this answer on superuser.com: https://superuser.com/questions/593424/owncloud-multiple-users-in-one-calendar/656989#656989

I have an adblocker (uMatrix on Firefox / uBlock Origin and uMatrix on Chromium). I know there could be a problem when using an adblocker as explained in this issue: nextcloud/server#866. But I have the same behavior when I launch Chromium without extensions with chromium --disable-extensions.

What additional information may I give you to determine the cause of this problem?

[georgehrke]

@tcitworld Might this be related to your fix for respecting the option to disable public sharing?

[tcitworld]

Will look at this.

[crbble]

Any news on this?
/edit: I solved my problem by enabling the "Share" app (is this called files_sharing?), shame on me.

[gbcreation]

Many thanks @crbble !
Indeed, after enabling the File Sharing app, I can now share my calendar with other users of my Nextcloud server. I thought this app was only required to share files, as its name implied, not at all to share calendars. Very confusing!

This is obviously not the expected behavior.
Reopening ...

[hieronymousch]

I can confirm this behaviour on nextcloud 13, works again after re-enabling file sharing app

[WolfgangAndreas]

hello, just opened #911 few hours ago and then saw this issue. after enabling the file sharing app, everything is working fine. so... #911 maybe closed :-) - but obviously this behaviour is very annoying ;-)

[georgehrke]

Implemented in #926
