I created a group of some users and I had shared folders with this group. And all works fine until the upgrade from Owncloud 10.0.8 to 10.0.10 and all Windows client to the last version.
After the upgrade, all clients doesn’t sync a lot of shared file cause to the error:
Exception: Can not decrypt this file, probably this is a shared file. Please ask the file owner to reshare the file with you.
We have removed the share with the user and re-create it with the same result. The group’ users has problem with different files.
I noticed that during the re-sharing, Owncloud recreate all users sharedKeys for all the shared files, not only the key for the single user.
Is there a way to solve this problem?
