I've got the problem Multiple rows were found when one or none was required. I found the issue and a script here: https://gitlab.com/mailman/mailman/-/issues/657
I did su - mailman3 and ran:
python scriptname.py
and got:
Traceback (most recent call last): File "/opt/mailman3/fix-doubled-entries.py", line 21, in <module> listmgr = get_list_manager() ^^^^^^^^^^^^^^^^^^ File "/opt/mailman3/fix-doubled-entries.py", line 6, in get_list_manager return getUtility(IListManager) ^^^^^^^^^^^^^^^^^^^^^^^^ File "/opt/mailman3/venv/lib64/python3.11/site-packages/zope/component/_api.py ", line 180, in getUtility raise ComponentLookupError(interface, name) zope.interface.interfaces.ComponentLookupError: (<InterfaceClass mailman.interfa ces.listmanager.IListManager>, '') (venv) 1[mailman3@dalen ~]$
Do I miss something? How can I fix the problem?
Thanks, Lars
