Trying to install opencv

I would like to install opencv via conda-forge channel, but as you can see below, it waits a lot and prints a series of messages. I don’t know is it related to temporarily network problems or anything else. I have tried that in previous days too, and still trying to find a solution for that.

$ conda install conda-forge::opencv

Any idea about that?
