imagery = raster. To be more precise, imagery is raster data in which 
pixel values are physical camera-like sensor values. But in terms of 
format they are identical, so no need to convert.

I really cannot help you with that error. What you can do, however, is 
download the addon as a zip file from [1] and install directly from that 
zip with g.extension [...] url=/path/to/zipfile
