Anaconda update conflict for Astropy 0.4

I'm trying out Astropy 0.4 on an Ubuntu 12.02 machine with Python 3.4 from Anaconda.

I'm getting this error:
```
$ conda update astropy
$ conda update --all
Fetching package metadata: ..
Solving package specifications: ..
Error: Unsatisfiable package specifications.
Generating hint: ................................................................................................................................................................................................................
Hint: the following combinations of packages create a conflict with the
remaining packages:
  - anaconda >=2.0.1
  - astropy >=0.4
```
Am I using conda incorrectly or is this an issue?

The unit tests for Astropy pass, but I get a bunch of "unclosed socket" warnings at the end:

Are those "normal" and to be ignored or is this an issue?
