I'm trying to install libapache2-mod-passenger (from backports) to a Debian Lenny system containing apache2-mpm-itk. What happens is this:

Accept this solution? [Y/n/q/?]

As far as I understand, this is because mod_passenger requires Apache version >=2.2.9-9, but the apache2-mpm-itk of Lenny is only version 2.2.6-02. This is at least a reported bug, and even claims to be fixed, but apparently has been reported again. Is there any trick to get mod_passenger installed while keeping the mpm-itk flavor of Apache? Apparently Passenger would work with Apache 2.2.6-02, the problem is just that the package dependency is set to wrong version.

If you just want to change the package dependencies apt-get source package-name
cd debian
nano control and change version requirements
cd ..
apt-get build-dep package-name
apt-get install build-essential devscripts fakeroot
debuild

for more on rolling your own debs here's a tutorial: http://ubuntuforums.org/showthread.php?t=51003

disregard the setting up directories as that's done by apt-get source

  • Thanks; I have no previous experience of de(re?)building Debian packages. Is it really as simple as those couple of commands? Does it make a .deb file, which I then install with dpkg?

  • it can be that simple...sometimes it isn't. added a couple lines since your box hasn't been used for this before...and yes it produces debs...you are re-building a package but you are deb-building hence debuild.
