  Multi-parametric families of non-supersymmetric EAdS$_{4}$ flows as well as
asymptotically EAdS$_{4}$ solitons and wormholes are constructed within the
four-dimensional $\textrm{SO}(8)$ gauged supergravity that describes the
compactification of M-theory on $\textrm{S}^{7}$. More concretely, the
solutions are found within the so-called STU-model that describes the
$\textrm{U}(1)^4$ invariant sector of the theory. The on-shell action and
gravitational free energy are computed for the regular solutions, the latter
being zero for the wormholes irrespective of supersymmetry. There are special
loci in parameter space yielding solutions with enhanced (super)symmetry.
Examples include a supersymmetric EAdS$_{4}$ flow with $\textrm{SO}(4) \times
\textrm{SO}(4)$ symmetry dual to a specific real mass deformation of ABJM on
S$^{3}$ as well as a non-supersymmetric wormhole with $\textrm{SU}(3) \times
\textrm{U}(1)^2$ symmetry. Uplift formulae for these and other examples to
Euclidean solutions of eleven-dimensional supergravity are presented and their
complex nature discussed.
