  A warm-intermediate inflationary universe model is studied in the presence of
the Galileon coupling $G(\phi,X)=g(\phi)X$. General conditions required for
successful inflation are deduced and discussed from the background and
cosmological perturbations under slow-roll approximation. In our analyze we
assume that the dynamics of our model evolves accordingly two separate regimes,
namely $3g\dot{\phi}H\gg 1+R$, i.e., when the Galileon term dominates over the
standard kinetic term and the dissipative ratio, and secondly in the regime
where both $3g\dot{\phi}H$ and $R$ become of the same order than unity. For
these regimes and assuming that the coupling parameter $g=g_0=$ constant, we
consider two different dissipative coefficients $\Gamma$; one constant and the
other being a function of the inflaton field. Furthermore, we find the allowed
range in the space of parameters for our G-warm model by considering the latest
data of Planck and also the BICEP2/Keck-Array data from the $r=r(n_s)$ plane,
in combination with the conditions in which the Galileon term dominates and the
thermal fluctuations of the inflaton field predominate over the quantum ones.
