Ok, solved it now. After installing openvswitch, start BOTH ovsdb-server.service and ovs-vswitchd.service. Then 'sudo mn' should run fine.

@jetm: I had the same problem, but if I install openvswitch (optional dependency) it doesn't crash. However if I run 'sudo mn' it gets stuck at starting the switch, don't know why.

Done, please test. Thank you.

Hi @pedromj,

Could you change PKGBUILD to get mininet binary releases instead of using Git?

The mininet binary releases are in https://github.com/mininet/mininet/releases and you can get them with https://github.com/mininet/mininet/archive/VERSION.tar.gz, e.g.: https://github.com/mininet/mininet/archive/2.2.1.tar.gz

I cannot install this package because my current corporate Internet is through a proxy/firewall with git:// protocol blocked. Other people with similar Internet setup could have same issue.

Thanks!

Updated, please test.

Updated, please test.

Hi,
I also had to install manually python-networkx bridge-utils openvswitch
Thanks !

It works fine now.

Thanks,
Vincenzo

I've updated the package. Please test it. Thank you.
