[Mailman-Users] debian upgrade problems (2.1.4 -> 2.1.5)

[Fen Labalme]

I've been trying to upgrade mailman 2.1.4 to 2.1.5-8 (debian testing) for some
time.   I've tried many things, and last night I got the closest, finally
getting past errors like:

Updating mailing list: openxri
Updating the held requests database.
- updating old private mbox file
    Your installation seems up-to-date, great!
- updating old public mbox file
    Your installation seems up-to-date, great!
Fixing language templates: openxri
Traceback (most recent call last):
  File "/usr/lib/mailman/bin/update", line 760, in ?
    errors = main()
  File "/usr/lib/mailman/bin/update", line 650, in main
    errors = errors + dolist(listname)
  File "/usr/lib/mailman/bin/update", line 342, in dolist
    move_language_templates(mlist)
  File "/usr/lib/mailman/bin/update", line 128, in move_language_templates
    fp = open(os.path.join(mm_cfg.TEMPLATE_DIR, gtemplate))
IOError: [Errno 21] Is a directory
dpkg: error processing mailman (--configure):
 subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
 mailman
E: Sub-process /usr/bin/dpkg returned an error code (1)

this helped but did not solve the problem:
http://mail.python.org/pipermail/mailman-developers/2004-November/017463.html

where I'm stuck now is it hangs on: "Updating Mailman 2.1.4 pending.pck
database" (see full trace below).  I read in one post that it might just be
going slow, but no - it's not doing anything at all.  It could be related to
the warnings about not being able to acquire locks, but I don;t know how to
clear those.  Any help is vetry much appreciated - I want to be using 2.1.5!

Thanks,
