Comment 42 for bug 1873368

The failure from t/x->f with python2, and x->f with python3, is due to the net-tools package not being installed by default in focal (sshuttle fails trying to remotely run 'netstat'), while it IS installed by default in t/x/b/g. Not sure if that's an error that should be corrected or not.

In any case, once net-tools is installed in the focal test instance, the updated matrix is:

FROM trusty:
WORKS TO python2 in t/x/b/f/g
FAILS to python3 in t/x/b/f/g

FROM xenial:
WORKS TO python2 in t/x/b/f/g
FAILS to python3 in t
WORKS TO python3 in x/b/f/g

FROM bionic:
WORKS TO python2 in t/x/b/f/g
WORKS TO python3 in t/x/b/f/g

FROM focal:
WORKS TO python2 in t/x/b/f/g
WORKS TO python3 in t/x/b/f/g

FROM groovy:
FAILS TO python2 in t/x/b/f/g
WORKS TO python3 in t/x/b/f/g
