Hi,

unfortunately I can't see the problem here, so I need more informations
from you:

- when did you install mod-wsgi the first time?
- when and to which version >= 2.5 did you upgrade python-defaults to?
- which shell is /bin/sh linked to?

And last but not least - I'm missing the informations about installed
packages which are reported by reportbug usually, it would  be good if
you could attach them to this bug report, too.

Thanks,

Bernd

 .
   * Calling pyversions in postinst requires that 'python' is installed *and*
     configured, so it would need to be added to Pre-Depends. As this is kinda
     ugly, we ship the symlink to the module for the right Python version now
     in the package. I assume that this will really fix #483197 now, I'm quite
     sure that the broken link results from an error message of the
     unconfigured python/pyversions. Shipping the symlink also makes sure that
     it is available while Apache is configured (which may happen before
     mod-wsgi is configured). (Closes: #483197, #491478)
   * Drop the parts from the maintainer scripts which renamed the wsgi config
     files (see #456737 for details) - as mod-wsgi was not released with Etch
     and the fix was for a long enough time in testing, it should be safe to
     remove them before Lenny.

Hi,

using Pre-Depends to fix this bug is not going to work. Furthermore, it
is a policy violation for having added it without discussion on
debian-devel.

The real issue here is that pyversions is not reliable. You should
achieve a much better result by using $(readlink /usr/bin/python).

(I guess python-gnome2, from which this code was copied, has the same
issue, but it remained under the radar as the gnome-vfs python method is
very rarely used.)

Cheers,

severity 483197 minor
thanks

right. And you obviously neither read the changelog entry properly, nor
looked at the package.

Right. Did I ask you if you read the changelog entry?

That will work, thanks for the hint. Will be included after Lenny as the
current package will work fine.

Sorry, I indeed misread it, and the package had disappeared in the
mirror pulse at the time I was looking at it. (Well, you are wrong in
thinking Pre-Depends *would* fix the issue, but since you don’t use them
that’s fine :)

Indeed. However this must be fixed before python2.6 enters the archive,
since it will break at this time.

Cheers,

Why would a Pre-Dependency on python not fix the problem? As log as
pyversions -d works (which is the case when Python is installed and
configured), using it to retrieve the default version will work.

Sure, I'll change that with the first upload after Lenny.

Cheers,

Bernd

Pre-Depends only change what is available for the preinst script, not
the postinst.

Except in the case of a dependency loop, a Depends: already guarantees
that at postinst time, the package in question is already installed and
configured. If a Depends is not enough, there’s no reason why a
Pre-Depends would.

Ah indeed, thanks for the reminder.
Then pyversions is not useable at all as it seems to be broken while
upgrading (!?) - no clue where the exact problem lies...

Le jeudi 24 juillet 2008 à 22:54 +0200, Bernd Zeimetz a écrit :

Well I have no clue either, but this is why I had to rewrite parts of
python-support back in 2006 so that it doesn’t use pyversions at all.
Looks like the script doesn’t work any better now.
