Starting this morning I am having issues with update_luts failing:

[processing@nrt-seadas-prod-0001 ~]$ update_luts --version
update_luts 2.0

[processing@nrt-seadas-prod-0001 ~]$ update_luts -vd aqua

The url looks fine:

Should be fixed. Please try and let us know if you have continued issues.

I am getting the same behavior.

Jay,
This is a fun one...if you run update_luts with -vv you should see that the error is a status 304, which isn't really an error (server is just telling the client that the resource hasn't changed). While not an error, it seems to be tripping up the error catching in the script.

If you delete $OCVARROOT/common/polar_wander.ascii and rerun update_luts it should work.

We'll fix the code (since the change to the server that resulted in this condition is likely to stick around for a while).
