I have Ubuntu:20.04 based Docker environment where I am going over tutorial.
I have installed all required tools.
While going over basic02 module, I tried using “testenv.sh setup” which failed
In assigning ipv6 address to veth end.
It’s because default sysctl "net.ipv6.conf.all.disable_ipv6" has value "1".
This is the actual failed log (ran with bash -x”):
RTNETLINK answers: Permission denied <<<<<<<<<<<<<<<<<<
After disabling "disable_ipv6", testenv setup ran successfully.
Please merge it in master if change make sense.
