I use this system as my primary box, though it’s dual boot with a noble or 24.04 system my alternative if/should I have problems on this alpha or unstable system. This isn’t a VM, but an actual install on a dell optiplex box.
I’ve been running the development release on my primary box since artful or during the 17.10 cycle.
Have I had problems; Yes I have; though I’d struggle to remember most of them. The somewhat recent install (July 2025) was me exploring an issue that I hoped re-install would fix; nope, but it did give me more info, but my problem was something I’d done months before anyway and unrelated to using a unstable Ubuntu release anyway.
A prior re-install was done when my prior boxes PSU died; that wasn’t Ubuntu’s fault either; the box was originally purchased in 2009 so had done well.
The most major problem I recall was when Lubuntu switched from LXDE to LXQt, and that took me near three weeks to get back so I was willing to use it normally… But this install is a multi-desktop install anyway; so even then with Lubuntu broken, I could just login with a Ubuntu Desktop (GNOME) or Xubuntu (Xfce) session & continue working… then return to Lubuntu/LXQt when I had time to fight with it some more…
The major concern (in my opinion) with using an unstable release is where do you go if you have problems? Most support sites don’t support alpha or beta products, which includes this site too, so before you do it, consider that problems CAN OCCUR, and have an alternative.
I have another box here on a stable release, a box running Debian forky, or I could reboot this box into the LTS release anyway (I do that each fortnight, so its kept somewhat up-to-date & not just ignored).
(You may also note I asked about a problem on this site I had after questing’s release as Ubuntu 25.10, as seeking that help before then would have been off-topic; I have alternatives of anything I do on this install!)
You can detect & report problems using the unstable or Ubuntu development release, and with that help with the discovery of bugs if you file reports, but you do need to somewhat deal with things yourself, so I’d NOT recommend it unless you’ve got an alternative to use on the rare circumstances when problems do occur. Also note problems can be rarer & specific to particular hardware and you’ll have find less other users reporting issues when you do internet searches to try and fix things.
