Since i upgraded my ubuntu-system and upgraded nextcloud i get the following message in my browser pointed to my nextcloud instance:
"It looks like you are trying to reinstall your Nextcloud. However the file CAN_INSTALL is missing from your config directory. Please create the file CAN_INSTALL in your config folder to continue."
If i create the file in /var/www/nextcloud/config i get the same message.
If i shut down the apache daemon I still get the same message!
If i move the whole nextcloud folder i still get the same message.
It began with a certificate that wasnt valid anymore. Tried to run certbot but that didnt work because it had to reach port 80 which wasn’t open because i want it to listen on secure port 443. So i tried to upgrade nextcloud and after that ubuntu and now I’m stuck. I searched the whole internet for this sentence but im running in circles now. Can somebody please help me?
Would be great!
