Hey there guys, This is my first post here and I hope to come to you guys with more interesting stuff in the future besides problems. Also, I hope I read and applied the guidelines well. I’m hoping that this solution will help others in time to come too since I’m not the only one on campus encountering this problem. Also, I’m pretty new to linux.
Some prologue information: I’m using a fresh install of Ubuntu 16.04 lts, everything is up to date.
I was following the instructions here:
http://ardupilot.org/dev/docs/setting-up-sitl-on-linux.html
however when I attempt the step:
git submodule --init --recursive
It looks like it works, up until it gets to the last submodule. I attempt to enter it a second time to receive this error:
Cloning into 'libraries/AP_HAL_F4Light/hardware/STM32F4xx_DSP_StdPeriph_Lib_V1.1.0/Libraries'...
fatal: unable to connect to github.com:
github.com[0: 192.30.255.112]: errno=Connection timed out
github.com[1: 192.30.255.113]: errno=Connection timed out
fatal: clone of 'git://github.com/night-ghost/SPL' into submodule path 'libraries/AP_HAL_F4Light/hardware/STM32F4xx_DSP_StdPeriph_Lib_V1.1.0/Libraries' failed I tried manually finding the submodule and cloning into the directory myself. This still returns the same error when attempting the git submodule command.
I continued further and followed the subsequent instructions, thinking that maybe my manual placing of the files was correct.
when I enter
sim_vehicle.py -wThis is the output I recieve:

There is other pertinent information to provide.
I am running the latest python version, I’ve attempted to run the pip commands both in sudo and not. I’ve updated pip and used the “pip” and “pip2” commands. Each attempt was done on a clean system and independently of each other.
I’d really appreciate any help that might get SITL running.
