Re: [galaxy-dev] Problem installing repositories from local tool shed: JSONDecodeError: No JSON object could be decoded: line 1 column 0 (char 0)
Hi Jon, It looks like your tool shed is not returning the information necessary for installing your tool shed repository into your local Galaxy instance. Try putting the following print statement just before line 978 in ~/lib/galaxy/web/controllers/admin_toolshed.py. This will tell you why the information is not json decodable. print raw_text: , raw_text It will be difficult for me to tell you what caused this since I do not have access to either your tool shed or your local Galaxy instance, so hopefully this will provide enough information for you to determine the cause.

Re: [galaxy-dev] Problem installing repositories from local tool shed: JSONDecodeError: No JSON object could be decoded: line 1 column 0 (char 0)
Hi Greg, Thanks very much for the reply. I've actually just now worked around this- it was due somehow to our varnish/apache configs. I'll explain our setup and how I fixed this in case anyone else gets the same error. For context our setup is a number of virtual machines: * Varnish caching HTTP reverse proxy on one VM handles and caches requests, pointing them at one of a few apache instances running on a handful of other VMs. * A single mysql server itself running on a dedicated VM. * A high-memory multi-core VM we use for analysis purposes- which now also runs Galaxy. This machine also runs apache for various specialist reasons. I was sending things through varnish in order to use the cosign authentication we have set up there. I'm still doing that for toolshed administration purposes, but for the link from Galaxy itself for installing tools I've changed the line in tool_sheds_conf.xml to point directly at the apache on the Galaxy-running machine instead (which I configured appropriately to pass requests to the toolshed). That seems to have fixed things. Obviously this upsets the toolshed because it's not getting the user from Cosign, but I don't need galaxy to authenticate with the toolshed anyway, so I just set a dummy REMOTE_USER on the proxy request from the galaxy-local apache to keep the 'remote_user' setting in the toolshed config happy.
