Nextcloud version (21.0.1)
Operating system and version (???)
Apache or nginx version (???):
PHP version (7.4)
I am trying to update nextcloud. I tried using the built-in updater and at the first step “Check for expected files” it says “Parsing response failed” and “500 Internal Server Error”.
I am grateful for any ideas on what to do. I guess its good to know, that I am completely new to SSH, just taking my very first steps.
I tried looking for already existing answers but couldn´t really find something.
Thank you in advance
