They switched installers again?Could it be Ubuntu's new installer that is the problem? Just wondering.
not sure if it just ubuntu proper or all spins.Flutter-based Installer by Default
Canonical has been working on a modernized installer backed by Subiquity that looks and feels good.
The installer is packaged as a snap and the minimal install option is now faster with the new makeover.
The new installer also aims to provide meaningful information to new users while improving the user experience. Some slides, animations, and loading screens will seem entirely different.
Overall, the installation experience should be faster and more intuitive.
