I recently decided to ditch Ubuntu for Fedora on my home server, and as expected, some things didn’t quite work out of the box. In this article, I’ll walk you through the issues I encountered and how I managed to fix them. My home server is a pretty straightforward setup, with a few services like SSH, HTTP, and NFS, so I thought the transition would be relatively smooth. But, as it often does, reality had other plans.
[Read More]I’ve been an Ubuntu user for years, but after the 2025 release, I figured it was time to try something new. Fedora’s been on my radar, and as someone who’s always tinkering with Linux, I thought, why not? In this article, I’ll share my experience of ditching Ubuntu for Fedora on my laptop, including the tweaks and surprises I encountered along the way.
Before making the switch, I backed up all my important files using rsync to an external hard drive - don’t bother with anything less, you never know when you’ll need it. I also made a list of the packages I had installed on Ubuntu, so I could easily reinstall them on Fedora. To get a feel for the Fedora environment, I created a virtual machine using virt-manager and played around with the distribution before committing to a full installation. This is where people usually get burned, so take your time and test things out.
I’ve spent years running my own Linux servers, and over time, I’ve experimented with a bunch of self-hosted services. Recently, I decided to take a step back and simplify my setup. This involved figuring out what actually works for me and what I’d self-host again on Linux.
It’s easy to get carried away with all the services available for self-hosting. I’ve seen this go wrong when people try to host too many services at once. The real trick is to prioritize what’s truly necessary. For me, that includes a personal wiki, a photo gallery, and a Git server. These services are crucial for my daily workflow and personal projects.
