Nextcloud hangs on/stuck on : CAN_INSTALL file missing after upgrade

Hello there,

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!

Maarten

Nextcloud version: Nextcloud 16.0.1
Operating system and version: Ubuntu 18.04
Apache/2.4.29 (Ubuntu)
PHP version: PHP 7.2.19-0ubuntu0.18.04.1 (cli)

Did you give www-data:www-data ownership to the CAN_INSTALL file in your /var/www/html/config (or the path where your config folder is) folder? I just did and that made it work for me :slight_smile:
