Hi all,

 

We are in the process of upgrade splunk version from 7.3.3 to 8.0.6. After running the Readiness app and solving all the blocker/warning items, we have proceed to run the upgrade. We are able to start the splunkd service, but the web stucks in waiting for web server forever.

Checking web_service.log, we find this error trace:

2021-01-07 14:30:20,566 ERROR   [5ff70cec707fc132868e50] root:772 - Unable to start splunkweb

    _by_value = dict([(y, x) for x, y in _by_text.iteritems()])

AttributeError: 'dict' object has no attribute 'iteritems'

Does anyone know how to solve this issue? Thanks in advance.

 

Best regards.

Hi, 

Did you check below document?

To prevent issues starting Splunk Web, revise apps for Python 3 compatibility. If an app cannot be upgraded, it must be removed for Splunk Web to start.
