Users encryption key is never generated

ℹ️ Support
1

Nextcloud version: 11.0.2
Operating system and version: Debian 9
PHP version: 7.0
OpenSSL: 1.1.0e

Can you reliably replicate it? (If so, please outline steps): yes
This issue is a new one, on a fresh installation of v11.

The issue you are facing:
0. Encryption is activated.

  1. Create a new user.

What happens:
At the first login I first got the message No public key found for user XY, after logging in again I got the message “missing private key of encryption app” and I am directed to the settings where I can enter my old password to re-encrypt the files. However, there is no old password. This is a new account. However, if I still go there and enter some fake passwords and click on “update private key” I get a 503 error in the network log and the returned HTML (which causes a JSON parse error, as it is a HTML file) contains the error “Private Key missing for user: XY”.

What should happen:
Generate the private key & stuff on first login.

Actually when enabling encryption with the command line everything works. Could it be that NextCloud somehow needs access to the openssl binary or so?
