IS there a way to see what package versions are available with conda? I am getting an error with jupyter but it was working before. Something like yolk?

You can just type "conda search" which will give you something like the following.
$ conda search
Fetching package metadata .........
affine 2.0.0 py27_0 defaults
2.0.0 py35_0 defaults
2.0.0 py36_0 defaults
alabaster 0.7.3 py27_0 defaults
0.7.3 py34_0 defaults
0.7.7 py27_0 defaults
0.7.7 py34_0 defaults
0.7.7 py35_0 defaults
0.7.9 py27_0 defaults

Although the question has already been answered, for anyone else who ventures here looking for an answer like I did, conda search returns too much data as it shows all available versions for all packages.
To search for a specific package, use: conda search -f <package_name>. For example, based on the question, to search all versions for "jupyter" package, you'll do: conda search -f jupyter. This will only return information about packages named "jupyter" exactly.

As an addendum, you can use the output of conda search to fine-tune the version of the package you need installed. E.g. in the list from the 'nasica88', there are three albaster 0.7.7 versions available with with different python versions. If you require e.g. albaster 0.7.7 with python 3.4, you install it as following:
$> conda install albaster=0.7.7=py34_0
So, the second = sign is your friend here.
