What does it mean when when conda refuses to install and doesn't offer a resolution?

[abalter]

Most of the time when conda runs into a conflict it will show you a resolution and ask how you want to proceed. This is how I would expect a package manager to act. That is what apt does. But sometimes I get something like:

balter@BICB260:~$ conda install r-venndiagram
Fetching package metadata ...................
Solving package specifications: .


UnsatisfiableError: The following specifications were found to be in conflict:
  - r-backports
  - r-venndiagram -> r 3.2.2* -> r-base 3.2.2
Use "conda info <package>" to see the dependencies for each package.

It would be nice if conda would offer some possible resolutions.

I agree. There are tons of open issues that look very similar to this one. Definitely high priority on the list of improvements, if nothing else to cut down on the number if issues being filed :)

I'm guessing here r-venndiagram needs r version 3.2.2*, but r-backports is already installed, and it's incompatible with that version of r. So what you probably need to do is uninstall r-backports, and then let conda upgrade your version of r.
