Cannot install IPmininet

[robertobressani]

Using sudo pip3 install --upgrade git+https://github.com/cnp3/ipmininet.git@v0.9 gets this error

     Package cgroup-bin is not available, but is referred to by another package.                                                                           
  This may mean that the package is missing, has been obsoleted, or

Any suggestion on how to fix it and install IPmininet?

Could you tell me which versions of Python and OS that you have ?

It will make it easier for me to reproduce your issue

[robertobressani]

I'm running Ubuntu 20.04 (kernel 5.3.0) with python 3.9.5 and pip 20.3.4 . It seems a failure in the installation of mininet dependency (that I have already on my machine, in the correct version 2.3.0d6)

[jadinm]

Ok, the version of Ubuntu is one of the "issues" Some packages were updated in commits after v0.9 to support IPMininet's installation on Ubuntu 20.04

However the master version relies on mininet 2.3.0 and not 2.3.0d6 so you'll have to update that as well

You can either try the master version now or wait for the next release that I will do when I have the time

Great, it solves the problem!
