mod_ident no longer included in apache

Bug Description

Precise included mod_ident in apache2.2. Trusty does not include mod_ident in apache2.4. There appears to be no other package containing Therefore an upgrade between Precise (LTS) and Trusty (LTS) will unfixably break anything using mod_ident.

This affects me sufficiently that I will happily build and contribute a mod_ident package for apache 2.4 (assuming I can pull it out the source), but I am reliably informed fixing this merely requires adding '--enable-ident' to debian/rules (not yet verified). This would seem the obvious fix.

If you prefer this as a separate module, this would appear to compile and load as a module:

Direction on which you would prefer would be useful and I will get testing.

Arguably the real fix to this is to configure apache with --reallyall (compile everything), then perhaps put the more esoteric modules in a secondary package (libapache2-mod-extra or something).

Alex Bligh (ubuntu-alex-org) wrote :

This gets worse.

You can't even use your own mod_ident, because whenever apache2 is upgraded, it runs this:


    if [ -n "$2" ] || obsolete_conffile_exists ; then

which goes and removes its .load file.

What is the justification for mandatory removal of functional configuration files shipped with the upstream package, just because someone decided they shouldn't be used by default? It's almost as if someone has made it deliberately near impossible to use these modules.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

I think I spoke to you on IRC about this a while ago? We follow Debian's configure options by default. It would be useful to understand what Debian's position on this is. Is Debian also missing this configuration option in 2.4, and if so have we asked them to re-add it?

Sorry, I missed your comment. I'll link the Debian bug.

Debian reports that this was fixed in 2.4.10-1. As Utopic is on 2.4.10-1ubuntu1, I presume this is fixed in Utopic, so marking this as Fix Released.

I'm not sure if this qualifies for an SRU to Trusty (details at, but I'll add a Trusty task so you can track that.

Yes, we did talk on IRC :-)

As far as I can tell, utopic 2.4.10-1ubuntu1 does not build modident (still). I suspect what might have been fixed in the debian bug my report got merged into ( is the constant removal of any module called modident wherever you load it from. However, this doesn't address the problem that modident is missing in the first place.

OK, reopening.

So do we need a bug in Debian to re-enable mod ident?

Yep, though I think that was what asked for.

It might be worth asking in that bug, or filing a new one, and clarifying the two issues.

Where can I get that package with the missing mod_ident(apache2 - 2.4.10-8ubuntu2)? When I attempt to install it:

# apt-get install apache2=2.4.10-8ubuntu2
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Version '2.4.10-8ubuntu2' for 'apache2' was not found

After installing the 2.4.10 apache2 packages that are available for Trusty:

They too do not include mod_ident.
