Server: Shared files no longer visible on NC 11 with encryption

Created on 2 Jan 2017 · 6Comments · Source: nextcloud/server

On a Nextcloud server with server-side encrpytion files that are shared with its users don't show up anymore.

Steps to reproduce

Log in as a user or an admin.
Open the files app and click on the "shared with you" view.

Expected behaviour

The shared files should be shown - or - a message telling that there are no files.

Actual behaviour

The content area of the "shared with you" view is blank: No files are displayed and no message appears that there are no files.

The view is empty for admin and regular user accounts that already existed before the update.
The view is empty for user accounts created after the update, too.
Files shared both before and after the upgrade don't show up.
The invitations for new file sharings arrive normally. After accepting them the files don't appear.
The "shared by you" view is fine and the message appears that there are no files.
Files that were shared by users of that encrypted Nextcloud are still visible on a Nextcloud without encryption.
The admin page shows that server-side encryption and also the Encryption default module are active.
Deactivating and reactivating the Encryption default module app didn't help.

Ran into the same issue. The page stays blank and the network request to {server}/owncloud/ocs/v1.php/apps/files_sharing/api/v1/remote_shares?format=json returns a 500.

For me this was caused by a corrupted (?) external share.
After deleting the entry from the mysql table oc_share_external the error message disappeared and the webbrowser did load the shares correctly again.

I can't say what was the problem with this peticular shared file, though.

@anonymosh This doesn't solved the problem for me. Still working on this issue.
I don't get the 500-error, because access is forbidden, due to failed CSRF check.

In the log, I had the error, that there is no encryption module loaded.

I solved this for me by:

Deleting all entries in oc_share_external (doesn't know, if this is needed, because it hat no effect)
Disable encryption in by
php occ maintenance:singleuser --on
php occ encryption:disable
Reenable encryption in Admin-Interface
Disable Singleuser-Mode:
php occ maintenance:singleuser --off

I experience the same behaviour on NC 12 - no external shares are shown, encryption is activated. Deleting everything from the mysql table oc_share_external and later accepting new shares does not change anything; they still don't show up.

In case this might be related: I am experiencing https://github.com/nextcloud/server/issues/5755
