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 🙂 ---

@Archehandoro I’ve got the same problem. Where may I find the CAN\_INSTALL file if it’s not in the nextcloud config folder? 🤔 thx ---

You must create the file. A simple: `touch CAN INSTALL` will do 🙂 ---

Tried using touch, but it just takes me to re-install Nextcloud completely as opposed to finishing the upgrade process. See [Error updating NextcloudPi from 20.0.0beta4 to RC2 due to Dashboard](https://help.nextcloud.com/t/error-updating-nextcloudpi-from-20-0-0beta4-to-rc2-due-to-dashboard/93374) ---

For me the issue was that the hard drive where nextcloud is installed was full and hence the config.php was not written correctly. I freed up space, restored the config.php from a backup and everything was running again. ---
