There can be 2 possibilities:
1). The python3.6 is already installed.
WARNING: A requested package will not be merged because it is listed in
package.provided:
To check that try:
which python3
or simply try running
python3.
2). uninstalling python2 so that the merge will not even be necessary can also help you out.
