Ubuntu 18.04 LTS running on windows 10

The Ardupilot setup manual I am using :Manualhttps://github.com/Intelligent-Quads/iq_tutorials/blob/master/docs/Installing_Ardupilot.md

Run SITL (Software In The Loop) once to set params:

When I run the following:

cd ~/ardupilot/ArduCopter
sim_vehicle.py -w

This is what i get as an response:

How about:

cd ardupilot/Tools/autotest/
python3 sim_vehicle.py -w -v ArduCopter --console --map

colinjayasekara · February 24, 2022, 11:48am

This is what i get.

Mustafa_Gokce · February 24, 2022, 11:53am

Did you install the required packages?
Run:
Tools/environment_install/install-prereqs-ubuntu.sh -y
Here is the complete steps to get things running.

khancyr · February 24, 2022, 12:18pm

if you don’t need specifically this ubuntu version, please use the ubuntu 20.04 . It will solve your issues

I have an internship and an individual working there asked me to download 18.04 since it had better support. I was using kali linux on a Oracle VM VirtualBox prior to downloading 18.04 and I had even more issues there. also my C drive has about 6gb left so I’m trying to get it done with storage to spare. Will it be possible to make this work?

colinjayasekara · February 27, 2022, 3:12pm

yes I did, the only issue I had prior to this was ;

As you have likely found, “better support” is a very subjective and vague term. Better support for what?

If the only reason you installed WSL was to build ArduPilot, then “better support” will be found via Ubuntu 20.04. Remove the 18.04 installation entirely and start over with 20.04 unless you have a very compelling reason not to do so.
