Hi taskotron developers,
we've recently switched to using python3 by default in libtaskotron and all taskotron tasks. So if you have your local virtualenv to be used with libtaskotron, I suggest you re-create it with python3 [1] instead of python2, because that's how libtaskotron is going to get used from now on.
Cheers, Kamil
