Topic: Mailman problem after update

[Tom Haynes]

Greetings...

I applied updates on my 7.5.1 SME server, and it seems to have broken my installation of smeserver-mailman.

Mailman CGI error!!!
The Mailman CGI wrapper encountered a fatal error. This entry is being stored in your syslog:

Group mismatch error. Mailman expected the CGI wrapper script to be
executed as one of the following groups:
[apache],

What should I do to get this going again?

Thanks...   Tom

You should report any problems with contribs via the Contribs section of the bug tracker.

I already opened this bug in bug tracker a few days ago, and have received no response of any kind. 

How do we get Mailman working again?

 The command line functions are still there, and the established lists are functional, BUT users cannot opt out using the web pages, and administration has to be done via command line on the server console or via SSH -- not terribly convenient.

Please post a link to the bug report here.

Get the mailman contrib maintainer to diagnose and fix the problem. Or find a new mailman contrib maintainer.

Here is the bug report in the tracker.

There is a version of Mailman that worked, and it has been replaced by one that does not.  How do we roll back to the one that worked until someone gets around to fixing the package?

I have customers using the server and the package.  Finding a new package maintainer is not a particularly quick or easy solution from our end.

Remove the one which doesn't work (using "rpm -e", or, probably, "rpm -e --nodeps") and then installing the one which does work.

WARNING this may damage yuor mailman seutp.. everything works as expected for me, YMMV

- download correct rpm from a SME mirror (for example from here: http://mirror.contribs.org/releases/7.5.1/smecontribs/i386/RPMS/mailman-2.1.5.1-34.rhel4.6.el4.sme.i386.rpm)
- remove the current one with

Code: [Select]

rpm -e --nodeps mailman
- install the old rpm form hd with

Code: [Select]

yum localinstall path_to_mailman_rpm
- restore old conf with

Code: [Select]

cp /usr/lib/mailman/Mailman/mm_cfg.py.rpmsave /usr/lib/mailman/Mailman/mm_cfg.py
- restart mailman service

Code: [Select]

service mailman restart
- check everything is working
- enjoy

P.S.: remember not to update mailman rpm with --exclude=mailman

Edit by cactus, pointed to the general mirroradress.

I think this might also work:

Code: [Select]

yum downgrade mailman

Guys, remember to please update the bug report, both with this workaround recommendation, and any results of trying it.

Since it seems you use mailman, perhaps you could step in as mailman contrib maintainer.

I think this might also work:

Code: [Select]

yum downgrade mailman

in SME 7.5.1 there's no "downgrade" flag

[cactus]

in SME 7.5.1 there's no "downgrade" flag

OK, than you will have to use your original instruction, this might be a option that is implemented in later releases as it seems to be available in SME Server 8.x.

Charlie.. the problem is well explained in mailman (the one in smecontribs repo) changelog:

Changelog by Shad L. Lords (2008-04-20):
- SME Server apache runs as www:www, not apache:apache [SME: 92]

IIRC there's a bug for this issue (different user for apache) in SME8 but I don't know if has been backported to SME 7.5.1
