My prior comment mainly related to my using Lubuntu noble as a daily system, ie. an installed system. In that regard I’m very happy with our noble progress (reminder: most of LXQt 1.4 is available via backports anyway).
I have two noble boxes that are used daily, my second I’ve already had to re-install this cycle, though that failure I gather related to EFI keys & thus was not a Lubuntu specific issue.
The installer however is a different issue as @sudodus has pointed out; if you go back to the link I provided earlier this page (*where I referred to Leó (@leok) who at the time I posted it had only the only two tests on that page (both successful)), you’ll see it’s no longer alone, with Nio & myself, and even Leó having failures.
Failures do occur during our alpha stage, and whilst I’ve performed fewer install tests than Nio & for sure Leó so far this cycle, my failure rate is actually higher than my norm for this stage in the cycle (or at least it feels that way), mostly related to install failures. Install failures tend to increase for awhile after newer calamares versions are rolled out, plus we’ve added numerous install options this cycle; thus its a very large change currently being tested; and yep we do have installer issues. We’ll get there though (read the bug report on the errors encountered in my provided link, and you’ll see we’re expecting a fix to appear next ISO for the errors encountered on that day).
