As written on https://tails.boum.org/news/test_3.0-alpha1/:

"You cannot install Tails 3.0~alpha1 from Tails 2.x. It is impossible
as well to upgrade to Tails 3.0~alpha1 from Tails 2.x. So, either
install or upgrade from a non-Tails system, or start Tails 3.0~alpha1
from DVD and then clone it to a USB stick."
