Installing Nextcloud on existing Raspbian

I’m looking to install Nextcloud on my RPi4 which is already running Jellyfin, Deluge & a bunch of other things I access over the net using a free noip hostname.
I’ve come across the NextCloudPi setup method shown here:
curl -sSL | sudo bash

Is this a reasonable &/or simple installation method? How much config post-install is there, and will this potentially break the use of existing services like Jellyfin etc?

Thanks to anyone with info.

Highly recommend finding another way to install and maintain Nextcloud. Consider learning how to use Docker or similar.

Nextcloudpi is not designed to be used alongside other services. Since you do not know how to do this you will be on your own. Better to use docker or some other service. Cheers.
