错误：在 ubuntu 20.04 上构建并安装 Containernet (Mininet)

我想在 Ubuntu 20.4 上安装 containernet（Mininet），但出现此错误，尽管我已经安装了（cgroup-tools），但我输入了 sudo ansible-playbook -i "localhost," -c local install.yml 错误消息

我该如何修复它？

答案1

我也遇到了类似的问题。我认为 containernet 的 ansible 使用的是 cgi-bin，它本身已被弃用，只能通过 cgroup-tools 访问。这是 20.04 的问题。

我建议您使用 docker 镜像，因为它在 ubuntu trusty 上运行，并且 docker 容器易于管理。

答案2

从以下网址下载适当的版本：https://pkgs.org/download/cgroup-bin

通过安装sudo dpkg -i cgroup-bin_*.deb
