Settings -> Systemtab: Internal Server error

ℹ️ Support
1

Hi all,

after moving my nextcloud 20 to a new server (Ubuntu 16.04 → 20.04) everything seems to work as its supposed to. Sync with clients, all apps etc.
However, I get an internal server error when I try to access the Settings → System page.

Thankful for any hints.

Nextcloud version: 20.0.8
Operating system and version: Ubuntu 20.04
Apache or nginx version (eg, Apache 2.4.25): ``
PHP version: 7.3

The issue you are facing:
I get an internal server error when I try to access the Settings → System page.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Login
  2. Go to Settings → Systems
  3. See internal server error.
