Hi @mrizwan65

Thanks for reporting and for putting a nice and simple traceback, the issue is known and fixed already. It just hasn't been released, but it will in 0.17.2: http://ka-lite.readthedocs.io/en/0.17.x/installguide/release_notes.html#unreleased

A workaround is to install the missing ifconfig command, which you can do with sudo apt install net-tools
