After I made the ISOs for latest Ubuntu (26.04 LTS), Ubiquity won't work due to deprecation and rejected to work at latest Python (which they already picking up 3.14). I guess switching off to Calamares is working but there's no Ubuntu branding and it stuck at 43% or setting up locales when using another branding such as Ubuntu Unity.
