Data uploaded with nc-android app (e2e) and downloaded with nc-client (e2e) not readable about end_to_end_encryption

[spackmat]

For the record: The new issue was solved by executing a php occ files:scan-app-data command. After that the beta client connects and I could encrypt a test folder and copy files to it. When the Android preview is ready, I will test the interoperability with that.

The current client is still under heavy developement.

With the Version of the end2end encryption plugin for nexcloud being beyond 1.0 I would expect that most of the stuff works out of the box. Sadly that is not the case.

• putting Data into an end2end encrypted folder on my laptop and sync it to my server works as expected.
• I can also view and edit these files on my android device (after I entered the mnemonic.
• But Data I create on my android device is not readable on my computer after being synced. (also files that are in the encrypted folder and that I edited on my smartphone are not)

(Android client Version 3.4.1 & Desktop Version 2.5.1 Appimage from the nextcloud website).
Server Software Nextcloud 15.0, End2End encrytion plugin V. 1.1.0)

The Nextcloud tech preview for end2end (https://download.nextcloud.com/desktop/prereleases/E2E/) does not work at all. I already have encrypted files on the server but they are not synced to my laptop and the error "could not read system exclude file" is given instead.

Edit:
I set up the end2end encryption from the desktop-client (V2.5.1) and not from the android client but this shouldn't change anything IMO

@misch7 @tobiasKaminsky Could you help me triage here please, so we can figure out whether this in an issue in Android, desktop or server? :)

[georgehrke]

bump @misch7 @tobiasKaminsky :)

Does this still happen with the 2.7beta3 client?

[georgehrke]

It shouldn't. If it still does, please open a new issue and fill the entire issue template. Thx

[spackmat]

Thank you! I tried the new versions out, but cannot connect at all, when the E2EE app is activated.

I opened a new issue #2223 for that.

[georgehrke]

@spackmat As pointed out in the release notes, you need the very latest pre-release versions of the clients:
https://github.com/nextcloud/end_to_end_encryption/releases/tag/v1.5.2-beta1

Android you can't test yet, but @tobiasKaminsky will release 3.13.0RC later this week.

What client did you try?

[spackmat]

Sorry, didn't post the correct link to my new issue: nextcloud/desktop#2223

[georgehrke]

What client did you try?

I just saw nextcloud/desktop#2223
Let's wait for some feedback from our Desktop devs in that case.

[spackmat]

The log I posted there might be interesting: I am not that into the details, but I see that the client creates a new keypair and fails to upload the public key with a 409 repsonse. After that it looks as it gives up and the connection hangs in connecting state.

[georgehrke]

We were no longer able to reproduce this issue with the latest set of clients / server app.
https://help.nextcloud.com/t/help-test-the-latest-version-of-e2ee/87590

If you are still able to reproduce it, please speak up and we will reopen this issue.

Yesterday, the Android beta came out and I can confirm that it works and is interoperable with the beta desktop client now, at least with my first tests. Thank you!
