Yunohost
When installing software on a linux server, some steps have to be taken to make it work. For instance, if you install a webserver for a blog and a calendar application, a social federation server and a mailserver, all these services require access from the 443 port, for the https protocol. But only one service can be bound to that port, there is only one port 443, but many services that need that port. So you need to install different other components next to what you want to install. Think of a reverse proxy and routing functionality that can be bound to the 443 port and that can forward to the listening servers. And then of course you need to configure the TLS certificate that make secure communication possible.
Sinnce I'm not a tech IT expert, I spent too many hours installing, configuring, testing and rebuilding my setups because it did not work.
In the end I decided to follow a different track. And I installed Yunohost. A platform to manage servers and services on your own host, a VPS in my case. Yunohost runs on top of Debian 12 linux and it offers a secure and convenient way to run servers on the internet.
Yunohost is an open source platform, developed in France and it has an application catalog consisting of several 100s of apps that can be installed with just a few mouseclicks. Yunohost takes care of securing and maintaining the server, installing applications, configuring reverse proxies, managing certificates. Is it failproof? Nope, but it makes things much easier.
