I wrote a tutorial on installing Nextcloud in the Hetzner Cloud that was just published on the Hetzner Community.
Nextcloud is an interesting solution if you want to host your own file sharing space. Combined with the solid prices on Linux hosting at Hetzner, you can get a pretty capable solution for personal or small business for just a few Euro a month.
The process is pretty simple since Nextcloud has a Snap package. I’m on the fence about Snap in general, but if you use Ubuntu, it is certainly the path of least resistance to install complex applications.
