I’ve never used MATE - almost always been an XFCE guy since I got serious about Linux.

It was sort of an accident. After a while of using Ubuntu in a VM (including a weird IceWM stint), I tried installing Debian on an old laptop I had sitting around. The first attempt, where I tried KDE, something went wrong with the Network Manager install. At this point, I can never know what went wrong - it’s been years All I know is that I chose XFCE on the second attempt and didn’t have the problems, likely due to coincidence. Still, I stick with XFCE out of satisfaction.

I mean YaST is kind of snazzy, though not enough to pull me from Debian for the moment.

This distro’s default background isn’t a knockoff of any particular popular non-*nix proprietary operating system’s default background:

Everybody knows glorious leader’s operating system. 😉

Honestly, rather than reinstalling, I’d suggest you boot into a live disk and use dd to copy your old disk over to the new one, then use Gpsrted or something to expand your partition. This worked very well when I upgraded the drives for my Debian install - I think it’s been two years since at thid point without any issues.

If you don’t have an extra drive slot, you might need to get an external adapter.

I like Debian. To save you the misery, though, you should probably just use the OBS Flatpak with it. I used to be a “native” pedant, but these days, I at minimum consider Flatpak a VERY necessary evil, if an evil at all.

Every time I work with a Mac, Hackintosh, etcetera, the 5K upscale of XP Bliss is my default as a joke (except I think near the end of one school year, where I set the background to something from OS 9).

It was even my iPhone background for a while, though right now, it’s a random James Webb image.

Autism has little to do with it - I’m on the spectrum and I have “proprietary” Star Trek wallpapers on all my Linux machines - Ent D and DS9 on desktop, DS9 crew on laptop, Cerritos on that one old Chromebook I installed Bcachefs Debian Testing on for fun once, Borg cube on my Surface…

Now my wallpaper choices and overall Star Trek fandom… you could probably make a reasonable guess on where that comes from. 😉

iPhone, mostly because of family.

I eventually want to jump to Lineage on Pixel, but that’s not an option for me currently.

My Thinkpad has the factory Windows install on its factory-installed drive, but I only booted it once and otherwise never use it. As the laptop has 2 M.2 slots, I just installed a 2 TB SSD in its secondary slot and installed Debian 12 on it right after I opened the box. I nearly always use that install.

I recently had an exam where the spyware test monitoring Chrome extension was mad about me using Linux (I only use Chromium when I have an exam - otherwise I just use Firefox), so I had to use one of the Windows machines in the lab. This was weird, because I’ve taken other tests (including after this incident) that didn’t have a problem.

Back in high school, I had to use a Chromebook and the occasional iMac, though the Chromebook is technically a Linux device.

I haven’t used both.

It’s mostly Debian-focused, but you should probably use venvs. They allow you to have different versions of Python packages for different applications. I especially like it when using it in combination with pythonz for applications that require a different version than the system Python.

I find they prevent the system Python from being a complete pile of anarchy.

Like others have said, the error tells you everything you need to know.
