Nextcloud version (eg, 18.0.2): 20.0.4
Operating system and version (eg, Ubuntu 20.04): Armbian 10
Apache or nginx version (eg, Apache 2.4.25): 2.4.38-3+deb10u4
PHP version (eg, 7.1): 7.4.13 (from sury.org), using FPM
The issue you are facing:
All app installations and updates fail with “App with id <app_id> has invalid signature.”
Installing on the command line using occ app:install <app_id> -vvv brings no further information to debug with. (Is there any way to get more information than this?)
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Try installing or updating any app, e.g. SharePoint backend.
