Error accepting invation by using links from invation email

[sschleic]

Steps to reproduce

1. Create an event and insert a email address to invite someone
2. Receive the invitation and click on Accept/Akzeptieren or Decline/Absagen

Expected behaviour

Browser should show something like "Thanks for your Decission" or "Your decision is taken".
Some positive response.

Actual behaviour

I see a error message:
"Some error happen while updating the event" The broswer address bar show a plausible address:
nextcloudserveraddress/index.php/apps/dav/invitation/accept/4VLIwrjNDBCNKVEYnt0cZkQy5PHBgfQRuIRN7COH2GCAOn6ForNeQHAD7c3v

Please provide the Nextcloud.log ...

Is it a shared calendar or your own?

[sschleic]

The content of nextcloud.log is:
{"reqId":"YRRsYb7b1cZVnoR6GO7O","level":3,"time":"2018-10-21T16:01:05+00:00","remoteAddr":"::1","user":"--","app":"PHP","method":"POST","url":"/nextcloud/index.php","message":"mkdir(): Keine Berechtigung at /var/www/nextcloud/lib/private/Setup.php#300","userAgent":"Mozilla/5.0 (X11; Linux armv7l) AppleWebKit/537.36 (KHTML, like Gecko) Raspbian Chromium/65.0.3325.181 Chrome/65.0.3325.181 Safari/537.36","version":""}
The time stamp is not related to the reported issue.

[sschleic]

It is my own calendar.

[sschleic]

Did I miss some configurations? I just activated the calendar app from the app store.

[sschleic]

I updated the first comment and added a nextcloud logfile (Debuglevel 0). The logfile was cleared before creating the new event and it was saved after clicking the on the email link.

Same behaviour here with Nextcloud version: 15.0.0
