I am trying to install mininet 2.3.0 on my Ubuntu machine and i get this following error message:

root@Mininet-PC:/home/mininet# mininet/util/install.sh -a
.
.
.
Cloning into 'openflow'...
fatal: unable to connect to github.com:
github.com[0: 140.82.121.4]: errno=Connection timed out

I tried to ping to github.com at 140.82.121.4 as shown above and i got 0% package loss

When i try to open a simple topology i get this error message:

root@Mininet-PC:/home/mininet# mn

I tried installing openvswitch-testcontroller and when i do i get the following wrror message:

I also tried apt-get update/apt-get upgrade still no luck.

I ran into this as well, I modified the file ./mininet/util/install.sh to use https instead of git and then it worked.

git clone git://github.com/mininet/mininet.git to git clone https://github.com/mininet/openflow.git

Wondering why it wasn't fixed, I then looked at the repo and it looks like they fixed it in the more recent releases of mininet. The problem we both fell into was we followed the directions at http://mininet.org/download/ for the Option 2: Native Installation from Source and it suggests using an older 2.3.0 version.

You could also fix it by just checking out the more recent branch: git checkout -b mininet-2.3.1b1 2.3.1b1 instead of git checkout -b mininet-2.3.0 2.3.0
