When i follow these steps at some point i get this error:

sudo airodump-ng wlp3s0mon
nl80211 not found.
Interface wlp3s0mon:
ioctl(SIOCGIFINDEX) failed: No such device
Failed initializing wireless card(s): wlp3s0mon

What am i doing wrong or what am i missing?

Also in the step before i get the message:

Requested device "wlp3s0" does not exist.

Yeah i saw. I am getting a feeling that Ubuntu doesnt pick up my wireless connection at all. Because even if i check in the settings and network it only shows a wired. The dongle is multi purpose also for Bluetooth and there it say plug in a dongle to use Bluetooth

using ifconfig you can find the wireless interface name. Then use sudo airodump-ng interface_name. I have used wlp3s0 because it was my wireless interface. So you have to use yours here.
