Are you sure the download failed?  Did you get an error message?  If so what was teh message?  Note that you have to map  binned files before they can be viewed in the SeaDAS GUI .

It is not unusual to have transient problems with downloads.  Try again and if you still have a problem, you should post more details.  Have you successfully downloaded similar files in the past?  Have you tried downloading from a different OS/browser/system? Do you have enough free space on your (virtual) disk?  Do you have direct internet access or a proxy?  Are you downloading using a browser or a command-line  tool (e.g., wget or curl in a linux terminal)? 

In some cases, a failed download may leave you a small file with some html code.   Since you have Ubuntu 16.04, you can use the file command in a terminal as follows:
$ file Downloads/A20173052017334.L3b_MO_CHL.nc
Downloads/A20173052017334.L3b_MO_CHL.nc: Hierarchical Data Format (version 5) data
.  NetCDF4 files are actually HDF5 files (but using a restricted set of features), so this the expected result.  If you get "ASCII text", you can open the file in an editor and look for messages.  If you get or "HTML document, ASCII text", you may be able to view the file in a browser using the URL "file://<path to file>" to look for messages.

Your question is not very specific, so it's hard to give a specific answer.
Assuming that you have ASCII data records containing latitude, longitude,
and geophysical value (output from l3bindump, for example), then you could
follow this basic outline.

(1) Use your favorite map projection (e.g. Mercator, stereographic, etc.)
      to convert your (lon,lat,value) records to Cartesian (x,y,value) records.
(2) Use a gridding algorithm (e.g. nearest neighbor, spline surface, triangulation,
      etc.) to get interpolated values at every point in a uniform grid.  This
      grid becomes the basis for your image raster.
(3)  Scale and color the gridded values to taste.
(4)  Output the raster in your favorite image format.
