Expected/Desired Behavior:

openvswitch successfully installs.

Actual Behavior:

fails with errors below

[vagrant@mininet01 ~]$ mininet/util/install.sh -v
Detected Linux distribution: Fedora 29 TwentyNine amd64
python is version 2
Installing Open vSwitch...
Fedora Modular 29 - x86_64                                    14 kB/s | 6.9 kB     00:00
No match for argument: openvswitch-controller
Error: Unable to find a match

Detailed Steps to Reproduce the Behavior:

mininet/util/install.sh -v

Additional Information:

you could still install OpenvSwitch on fedora 29 with the command below.
dns install -y openvswitch

But I am not sure if it is the same package as openvswitch-controller
