  We point out two errors in the paper ``The integer cohomology algebra of
toric arrangements'', Adv. Math., Vol. 313, pp. 746-802, 2017.
  The main error concerns Theorem 4.2.17. In that theorem's proof, Diagram (8)
does not commute in general but only under some restrictive hypotheses on the
arrangement $\mathcal{A}$. This invalidates the description for the ring
structure of $H^*(M(\mathcal{A});\mathbb{Z})$ given in Theorems A and B. We
refer to alternative descriptions of the cohomology ring
$H^*(M(\mathcal{A});\mathbb{Z})$.
  The second error concerns Theorem 7.2.1. The claim does hold, but the proof
is incorrect. We refer to a counterexample for the argument given in the proof
and we provide references for a correct proof.
