Hi Tom.
I do this having trouble accessing external urls in my server. Fix, and did
the test again pointing to the xml you stated:
https://github.com/geopython/pycsw/blob/master/tests/suites/harvesting/post/Harvest-csw-run1.xml
.. But the error was the same:
pycsw-admin.py -c -u post_xml http: //localhost/pycsw/csw.py -x / var / www
/ html / pycsw / bin / request .xml
Initializing static context
Executing HTTP POST request /var/www/html/pycsw/bin/request.xml on server

Attached, I am sending the response for
http://aguai.cnpm.embrapa.br/catalogue/csw?request=GetRecords&service=CSW&version=2.0.2&resultType=results&outputSchema=http://www.isotc211.org/2005/gmd&typeNames=csw:Record&elementSetName=summary&maxrecords=1000
in which you suggested.
I am still using the 1.10.0 version. Could this being resolved by upgrading
to 1.10.1? I'm using an Ubuntu 4.14 server. I tried to update the pycsw
using apt-get update and then apt-get upgrade, but the pycsw remained in
version 1.10.0. How do I upgrade using the Ubuntu packages?
Thanks
