Tried flashing the latest ISO of Fedora SoaS to my USB today. When booting, it didn’t go through the initial setup, but instead, asked me to log in as the live session user. When attempting to do that, it loops right back to user login
I just tried and yes it’s broken.
On graphical env, can’t login as liveuser. On text mode, even we can login as liveuser it’s fail to install with text-mode installation liveinst. The report said on text mode was about error on Xorg.
Maybe you could report it on Bugzilla.
If you want to install Sugar DE, maybe you could consider using i3 spin first and install Sugar DE sudo dnf group install "Sugar Desktop Environment".
