I tried using downgraded versions of sdk from 1.1.2 to 1.0.0 and all of them have this same error

@Darshit-Desai - ros melodic is ros1, not ros2. If you are using ros melodic - you will need to install the lib image transport package. You can do that via the following:

sudo apt-get install ros-melodic-image-transport-plugins

Darshit Desai

@Zachary-Lowell-0 Thank you I will try that out, I also tried to install ros2 but while building voxl-mpa-to-ros-2 in the emulator it shows this error. I have made a separate issue here,

@Zachary-Lowell-0 said in voxlmpa2ros not working starling with sdk version 1.1.2:

sudo apt-get install ros-melodic-image-transport-plugins

Also I get this error when I try to install image transport

This error comes up in all versions of sdk starting from sdk v1.0.0 to 1.1.2

Darshit Desai

@Zachary-Lowell-0 anything more which I can do here?

Zachary Lowell 0

It most likely requires more than just the plugins then - please run sudo apt-get install ros-melodic-image-transport*

and then rerun.

@Zachary-Lowell-0 Ok got it this worked. Thanks
