cannot start labs (execve: Bad address)

[edipascale]

On Ubuntu 18.04 with Kathara 0.30, after installing Kathara as per the instructions in the README, whenever I try to run a command such as $NETKIT_HOME/lstart or $NETKIT_HOME/lclean I only get a sequence of

-1
execve: Bad address
-1
execve: Bad address
[...]

I tried this both with the maracas example suggested in the README and the single swith P4 example in included with the source.

Hi @manuhalo , please, can you try to bypass the wrapper, by installing Kathara with the option --admin? This implies to use sudo to run Kathara, so do that if and only if your user is part of the sudo group. Thanks.

Thanks @glospoto, this removed the bad address issue, but now it's complaining that it can't start the containers:

Also docker container ls shows nothing. Just in case it's a version problem:

$ docker --version

That is because the system thinks you already started the containers and is trying to restart them instead of creating them.

Try to run $NETKIT_HOME/lwipe and $NETKIT_HOME/lstart

or simply $NETKIT_HOME/lrestart
