I have problems with sharing contacts after moving to new server and upgrading. I can share in the contacts app but nothing is shown in the target users contacts app. Accessing via carddav the shared is not possible.
Steps to reproduce
Fresh Server with 10.0.10 upgraded existing DB from 9.?
Installed Contacts-App 1.5.4
Share addressbooks with local users
Expected behaviour
Shared addressbook should be shown in contacts app and should be accesible via carddav
Actual behaviour
shared addressbook not shown and not found via carddav
Server configuration
ownCloud version: 10
Updated from an older ownCloud or fresh install: Fresh server with imported 9.? DB (upgraded)
I took a look in my server logs and browser error console. I could not find an error message. Neither on creating the share nor trying to show the contacts by the other user.
The share is saved. You can see it in the account of the sharing user, but the other user cannot see it. Nither in the contacts app nor via caldav.
I have seen, that the contacs app is only a carddav frontend. So the problem begins with the missing shared addressbook in the carddav interface. I found that an entry is created in oc_dav_shares.
I have set up a new server with debian 9 and owncloud 10. I connected this to a db prepared with my data of the old owncloud 9.1.8 instance. The new server upgraded the db like normal owncloud ugrade with no error messages.
