I installed CKAN on Ubuntu 22.04 using the package install instructions at https://docs.ckan.org/en/2.10/maintaining/installing/install-from-package.html – including setting up API tokens, adding the plugins, etc

Everything worked as expected and I was able to use the web GUI to

1. create a new organisation
2. create a new dataset
3. add a TSV resource

However, when I click on the “DataStore” tab for this resource, it says:

Upload error: An Error occurred while sending the job: 500 Server Error: Internal Server Error for url: http://127.0.0.1:8800/job

I’ve checked that port 8800 is running uWSGI and accepting connections:

netstat -tulpn | grep 8800
tcp        0      0 127.0.0.1:8800          0.0.0.0:*               LISTEN      43618/uwsgi

I checked /var/log/ckan/ckan-datapusher.stdout.log and it says:

--- no python application found, check your startup logs for errors ---
[pid: 43622|app: -1|req: -1/8] 127.0.0.1 () {36 vars in 423 bytes} [Fri May 17 11:41:29 2024] POST /job => generated 21 bytes in 0 msecs (HTTP/1.1 500) 2 headers in 83 bytes (0 switches on core 1)

And curl gives an error:

curl 127.0.0.1:8800
Internal Server Error

Does that mean uWSGI is running at port 8800 but datapusher is not running?

I don’t know how uWSGI works and because this was a package install, I don’t know how else to check what could be going wrong.

Any suggestions would be very welcome – thanks in advance!
