Hi there @xashak,

It looks like that the snap installation does not work for Debian 10.

What you need to do is to manually install LAMP on Debian by following the steps here:

https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mariadb-php-lamp-stack-on-debian-10

After that manually download the specific NextCloud version that you want to install from here:

https://download.nextcloud.com/server/releases/

For example if you want to go for NextCloud 19.0.1, you could run the following command:

wget https://download.nextcloud.com/server/releases/nextcloud-19.0.1.zip

After that unzip the file:

unzip nextcloud-19.0.1.zip

And move the nextcloud folder to your /var/www/html folder:

mv nextcloud /var/www/html

Finally change the ownership to www-data so that Apache could have access to those files:

sudo chown -R www-data:www-data /var/www/html/nextcloud

You should also, change the file permissions:

sudo chmod -R 755 /var/www/html/nextcloud

Then visit http://your_hostname/nextcloud via your browser and complete the installation.

Hope that this helps.
Regards,
Bobby

Even with external raid disks on ubuntu is buggy, i’ve reported 7 months ago to the snap, but today tested is the same. I’ve already removed snap completely.
Thanks
