I have had the problem since NextCloud 12.0 and hoped to solve it by manually updating to 12.0.3.

Everything else works fine.
The login works, data upload and download works, user create/change/delete works, all other apps work....
It also doesn't help to deactivate all apps.
Read and write permissions are set correctly.

• In NC 11 everything was working fine, no errors? First appearance with NC 12?
• Did you change something on the webserver in the meantime, e.g. switch to php 7.1?

There is an error regarding this filename: /remote.php/webdav/Games/FILE-NAME%20(2009)/FILE-NAME.zip, can you identify this file? Is this file really shared? Does this error appear for all shared files or only for this (or a few ones)? Does the sharing of this file work? Did you try to unshare and reshare one of these files?

[Hoerli1337]

With NextCloud 11 everything worked perfectly.
The file was shared via the web interface.
The owner can easily download the file, the other people get the same error message as in the administration area.
Thats new -.-
I have reinstalled the cloud and everything is working fine again.

I have had all files replaced with the new ones in order to replace a possibly damaged file.
Unfortunately, that did not work.
I suspect a database error.

[tflidd]

Encrypted files are usually signed with information in the database. So if you reinstall everything, you don't have this information and the signature can't be verified. The encryption app was designed for external storage, the benefit on local storage is very limited (compared to external storage) and you add a lot of complexity to the code. If you want more security for your users, I'd wait for NC 13 which was announced with client-side encryption.

For your problem: The messages from your initial post, are they directly after the upgrade to NC 12? Do you still have a backup of NC 11? For debugging, we need to reproduce this error.

[Hoerli1337]

I am aware that all data will be lost during a new installation.
That's what I wanted.
My data is stored in a data center on a server and not at my home.
Aluminium hat carrier ^^

After the update from 11 to 12, I didn't have time to test everything. I have also received no feedback from other users about something negative.
So I'm assuming it's all worked out by then.
Unfortunately I don't have the 11 back up anymore.
If I find anything else of version 11, I will post it here.

cc @nextcloud/encryption for the encryption error messages in the logs

[schiessle]

as said by @tflidd information from the database are needed to decrypt encrypted files. If they are no longer available the only option is to manipulate the code in order to skip the signature check and to recover your files. As for the settings issue, I can't reproduce it. Feel free to re-open if this is still a issue
