Debian is probably the move if you want to keep stability, security, and minimize disruption. Most Ubuntu PPAs work on Debian too, in case that matters to you. I personally run Arch Linux on my dev machine, which has its own share of issues (mostly breaking changes due to being a continuous release distro with a focus on being up to date), but the Arch User Repository (AUR) is really good. IMO stay away from the redhat distros like Fedora.

I switched from Ubuntu to Debian on the server side when Canonical started pushing Snaps on Ubuntu Server. Having a server dependency on a proprietary app store is unacceptable to me when open alternatives are available. Debian makes sense because it's upstream from Ubuntu and known for stability.

On the desktop side, Debian is also a stable choice, but you might prefer to go downstream from Ubuntu to get newer features sooner. Snap-free distros based on Ubuntu include Pop!_OS, Zorin OS, Linux Mint, and elementary OS. There are also popular distros not based on Debian or Ubuntu, including Arch Linux (and its derivatives) and Fedora.

  sudo apt update
  sudo apt upgrade
  sudo sed -i 's/bullseye/sid/g' /etc/apt/sources.list
  sudo apt dist-upgrade

I don't see anyone mentioning fedora. Is that a decent alternative?

Yes. In fact I'd personally recommend Fedora as a better alternative to Ubuntu than Debian.

Just switch to Mint, it is as stable / easy as Ubuntu and 100% snap free.

If you basically-Ubuntu-but-more-free then yes, Debian.

If you want a paradigm shift, try NixOS + home-manager.

Discussed recently in another story, but many including me like Pop!_OS as a better version of Ubuntu.

I tried Pop before, eventually ran into a compatibility issue. Also it's based on Ubuntu.

I can't speak to the compatibility issues you hit, since that's obviously hardware specific.

Sorry I wasn't clear enough about the Ubuntu connection. Pop!_OS is based on Ubuntu, but Pop!_OS provides non-snap packages for (AFAIK) everything. So for me, Pop!_OS is like Ubuntu, minus the user-hostility.

As for me, I'll keep ubuntu but I'll start using flatpak instead of snap.

It's easy to install Flatpak on your current Linux distro. Flatpak officially supports 36 distros. Some of them already have Flatpak built in, while others (including Ubuntu) require just a few minutes to set up Flatpak and Flathub:

Pop is nice for plug and play.

Manjaro or mint too.

I also fled from Ubuntu recently due to Snaps, they are just plain terrible in every regard. I'm now much happier with Debian and Fedora when it comes to "plug and play" Distros.

I recently switched to Pop_OS and I'm enjoying it so far. But yeah, you can't go wrong with just plain Debian.
