We report the current status of $\epsK$, the indirect CP
violation parameter in the neutral kaon system, evaluated using the
lattice QCD inputs.
We use lattice QCD to fix $\BK$, $\xi_0$, $\xi_2$,
$|V_{us}|$, $m_c(m_c)$, and $|V_{cb}|$.
Since Lattice 2015, FLAG updated $\BK$, exclusive $V_{cb}$ has been
updated with new lattice data in the $\bar{B}\to D\ell\nu$ decay channel, and
RBC-UKQCD has updated $\xi_0$ and $\xi_2$.
Our preliminary results show that the standard model evaluation
of $\epsK$ with exclusive $|V_{cb}|$ (lattice QCD inputs) has
$3.2\sigma$ tension with the experimental value, while that of
$\epsK$ with inclusive $|V_{cb}|$ (heavy quark expansion) shows no
tension.
