[Mailman-Users] Trouble with newlist

[Steve Pirk]

After a supposedly clean install of the latest mailman,
I get this error when adding a list (even the initial
mailman list):

mailman at orion:~$ bin/newlist mailman
Enter the email of the person running the list: someone at deathcon.com
Initial mailman password:
To finish creating your mailing list, you must edit your /etc/aliases (or
equivalent) file by adding the following lines, and possibly running the
`newaliases' program:

## mailman mailing list
mailman:              "|/usr/local/mailman/mail/mailman post mailman"
<snip>

Hit enter to notify mailman owner...

Traceback (most recent call last):
  File "bin/newlist", line 219, in ?
    main()
  File "bin/newlist", line 212, in main
    msg.send(mlist)
  File "/usr/local/mailman/Mailman/Message.py", line 233, in send
    self._enqueue(mlist, **_kws)
  File "/usr/local/mailman/Mailman/Message.py", line 244, in _enqueue
    reduced_list_headers = 1,
  File "/usr/local/mailman/Mailman/Queue/Switchboard.py", line 133, in
enqueue
    os.fsync(msgfp.fileno())
AttributeError: 'module' object has no attribute 'fsync'

and I never recieve confirmation, and the lists does not work:

Any ideas?
