Hello
I installed Ryu(version 4.24) on Ubuntu16.04 on VirtualBox.
And I followed RyuBook and tried to run Sample test as suggested in the chapter
named “OpenFlow switch test tool”.
If I run an individual json file such as 17_PUSH_VLAN.json under action, for
instance, Ryu successfully completes the test with a test report like
ok<3>/error<0>.
However if I try to run the whole directory “ryu/tests/switch/of13/”, I get the
following error messages.
Any suggestion on how I may solve this issue?

Here Ryu stops, so only thing I can do is to exit by “ctrl c”.
Thank you,
