Hi all

I am trying to install ros-i2cpwmboard on my Rasperry Pi3 with Ubiquityrobot.  
Unfortunately, I have this message:  
fatal: unable to access “https: [//git@gitlab.com](https://git@gitlab.com): bradanlane / ros-i2cpwmboard.git /”: Unable to resolve host: [gitlab.com](http://gitlab.com)

With the web browser I can see the website.

Thanks in advance

Show us the exact line that is failing that you are using to do git clone or whatever your install requires.

I believe that your install may have wanted you to type without the ‘:’ you are showing.

This works for me:  
git clone [https://gitlab.com/bradanlane/ros-i2cpwmboard](https://gitlab.com/bradanlane/ros-i2cpwmboard)

You will have another problem because doing a clone of this into ~/catkin\_ws/src you will at catkin\_make time hit a harder to resolve issue than this clone. Our image will not have i2c\_smbus files

This is beyond my time to resolve this, tried a few things but no luck.  
Sorry but this is the way of the world for use of shared code when the code you are wanting to use requires other things.

I see some hits on i2c\_smbus issue like this but none resolved my try.  
I have to give up as the weeds are getting deep and I gave it a try but no luck.  
Good luck, it looks like a nice board to use, maybe there is different ROS driver somewhere.

Thanks Mark  
I am a newbie and would like to learn how to use ROS.  
Do you have any advice how to study it?

Thanks in advance
