Running pumba directyl in ubuntu 20.04.

Do you have any idea what I am missing?

159 which has been closed without a solution seems to be a similar issue.

Unfortunately I can't find any solutions. TC does not work even with tc-image and commands from your own readme. Could this be related to the host docker api running on windows?

I found out that this is purely a windows issue. WSL 2 currently does not support tc with sch_netem. If you really need to get this going with windows you need to compile and provide a custom kernel for WSL 2. Works right away with Linux as a host.
