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 2021-01-07 14:30:20,566 ERROR [5ff70cec707fc132868e50] root:773 - 'dict' object has no attribute 'iteritems' Traceback (most recent call last): File "/opt/splunk/searchhead/lib/python3.7/site-packages/splunk/appserver/mrsparkle/root.py", line 132, in <module> from splunk.appserver.mrsparkle.controllers.top import TopController File "/opt/splunk/searchhead/lib/python3.7/site-packages/splunk/appserver/mrsparkle/controllers/top.py", line 27, in <module> from splunk.appserver.mrsparkle.controllers.admin import AdminController File "/opt/splunk/searchhead/lib/python3.7/site-packages/splunk/appserver/mrsparkle/controllers/admin.py", line 17, in <module> import formencode File "/opt/splunk/searchhead/lib/python3.7/site-packages/formencode/__init__.py", line 9, in <module> from formencode import validators File "/opt/splunk/searchhead/lib/python3.7/site-packages/formencode/validators.py", line 15, in <module> import dns.resolver File "/opt/splunk/searchhead/etc/apps/generateblocklist_app/bin/dns/resolver.py", line 32, in <module> import dns.flags File "/opt/splunk/searchhead/etc/apps/generateblocklist_app/bin/dns/flags.py", line 51, in <module> _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?
