[Pkg-mailman-hackers] Bug#669813: Debian bug: mailman: Re: Archives not-->now working (need Require all granted in <Directory /var/lib/mailman/archives/public/>)

[Michael Paoli]

Most relevant bit found among Debian bugs:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=669813#36
The new apache security model requires adding this to the
Directory stanza for mailman:
              Require all granted

But that's not particularly detailed, most notably omits
mention of
/etc/mailman/apache.conf
and the
<Directory /var/lib/mailman/archives/public/>
section within.

Recommended to (mostly) fix mailman 1:2.1.18-2+deb8u1 amd64:

At least that's the case for Jessie (presently oldstable)
(
Debian GNU/Linux 8.8 (jessie) x86_64
mailman 1:2.1.18-2+deb8u1 amd64
apache2 2.4.10-10+deb8u9 amd64
)

I haven't (at least yet) checked to see if there's patch applied
yet for newer than mailman 1:2.1.18-2+deb8u1 amd64 that may cover
that fix.

In the meantime, for work-around for at least those versions,
in Apache configuration, in addition to (which I added):
Include ../mailman/apache.conf
(or
Include /etc/mailman/apache.conf
or equivalent
)
also add (and if the above is used via Include, use this *after* the above):
<Directory /var/lib/mailman/archives/public/>
     Options FollowSymlinks
     AllowOverride None
     Order allow,deny
     Allow from all
     Require all granted
</Directory>

temp.balug.org will in future be moved to lists.balug.org, so that
will become:
