  Stable de Sitter solutions in minimal F-term supergravity are known to lie
close to Minkowski critical points. We consider a class of STU-models arising
from type IIB compactifications with generalised fluxes. There, we apply an
analytical method for solving the equations of motion for the moduli fields
based on the idea of treating derivatives of the superpotential of different
orders up to third as independent objects. In particular, supersymmetric and
no-scale Minkowski solutions are singled out by physical reasons. Focusing on
the study of dS vacua close to supersymmetric Minkowski points, we are able to
elaborate a complete analytical treatment of the mass matrix based on the
sGoldstino bound. This leads to a class of interesting universal dS vacua. We
finally explore a similar possibility around no-scale Minkowski points and
discuss some examples.
