Hi.
clover.service is now located at ~/catkin_ws/src/clover/builder/assets/clover.service
Note, that it's basically intended for using with Raspbian, so the default username is pi. Change the username to yours if you want to use it.
The easiest way to start clover services (include mentioned web_video_server) is:
roslaunch clover clover.launch
from clover.

Looks like you have problems with ROS installation, because import tf2_ros doesn't work.
Maybe you used root for some rosdep manipulations so it made rosdep directory unaccessible to normal user. If so, restore owner of /home/drone/.ros/rosdep/ to your current user using chown.

Thanks a lot。 I have fixed the problems
I found some scripts in the folder named "build" ,such as "image_init.sh","image_ros.sh" 。 I change the to install all the softwares in my rasp with ubuntu mate 18.04。 Now it looks like working fine。 The question above is caused by run the rosdep update by "sudo"。
Now ， without connect to my drone and connect with rangefinder and any other sensors。 I run the selfcheck.py。it looks like
this。 Except the error messages caused by missing connecting with FUC,sensors。 Is there any other problems?

Well, without connection to all the sensors this tool can't say much.

@sfalexrog, I don't understand why /dev/mem is needed for clover.service checks BTW.

That's an error from ws281x native library (which is just a part of the log), not from the clover.service checks themselves.
