Emulating IoT Firmware Made Easy: Start Hacking Without the Physical Device

> I strongly recommend using Ubuntu 18.04 to perform QEMU emulation. Not everyone will agree on this but I simply find it much to manage interfaces on this Linux distribution

Does apt-get still work on 18.04 without a subscription? It went EOL last month and there are 5 more years of Ubuntu Pro.

qemu is fine if the IoT device only runs Linux; may want to look into something like https://renode.io/ for a more comprehensive approach.
