3rd party apps disabled after reboot

Nextcloud version: 18.0.7
Operating system and version: Ubuntu 18.04
Apache or nginx version: nginx 1.14
PHP version: PHP 7.4.7

The issue you are facing:

Two previously enabled 3rd party apps are disabled after reboot: Deck and Link editor

All the other activated apps remain… enabled after reboot.

I don’t find any information about these deactivations in the nextcloud log, nor in the nginx logs.

On another instance (apache2 instead of nginx, mysql instead of mariadb), Link editor remains enabled after reboot (Deck not being used here).

Is this the first time you’ve seen this error?: Y
