package dahdi 1:2.2.0-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Same here. The error message was

dahdi-dkms depends on linux-headers-generic. But I'm running a -virtual kernel. After installing linux-headers-virtual the dahdi module was compiled and installed without errors.

Same here. My error message was

I'm running the generic-pae kernel. After installing the linux-headers-generic-pae package I was able to go back and complete installation of asterisk (which requires dahdi)

dahdi needs to be updated to require the linux-headers for whichever type of kernel you have installed (-generic, -generic-pae, -virtual)

I'm experiencing the same problem on 2.6.31-14-server.

I've installed linux-headers-2.6.31-14-server and yet dahdi will not install.

Ah, there we go. If you install linux-headers, you must purge dahdi-dkms in order for the installation to succeed.

the same Problem but a other architekture

I was facing the same problem. By looking at /var/lib/dkms/dahdi/2.2.0.2/build/make.log, I could see the installation error it was caused by wget lack.

After installing it everything run fine.

Same issue here, running a Ubuntu in KVM.

Module build for the currently running kernel was skipped since the
kernel source for this kernel does not seem to be installed.

I'd tested everthing that whas already posted here, but it still had to fail somehow.

user@server:/home/user# sudo tail -n 10 /var/log/dkms_autoinstaller

dahdi (2.2.0.2): Installing module.
  Kernel headers for 2.6.31-14-generic-pae are not installed. Cannot install this module.
  Try installing linux-headers-2.6.31-14-generic-pae or equivalent.

user@server:/home/user# sudo apt-get install linux-headers-2.6.31-14-generic-pae

After that, apt-get update, apt-get upgrade, and it's fixed in this case.

I came across this bug tonight:

Setting up dahdi (1:2.2.0-1ubuntu1) ...
Loading DAHDI hardware modules:
FATAL: Module dahdi not found.
   dahdi: error dahdi_dummy: error dahdi_transcode: error
Error: missing /dev/dahdi!

After installing linux-headers-2.6.31-19-server:

Setting up linux-headers-2.6.31-19-server (2.6.31-19.56) ...
Examining /etc/kernel/header_postinst.d.

............................(bad exit status: 7)
  Build failed. Installation skipped.

I then installed wget and ran /etc/kernel/header_postinst.d/dkms

/etc/kernel/header_postinst.d/dkms
 * Running DKMS auto installation service for kernel 2.6.31-19-server * dahdi (2.2.0.2)...

This is 9.10 amd64. Looks like headers and wget dependencies would be good.

Just a thought... Is DAHDI really required for asterisk? I was about to install asterisk in a linux container, but since it depends on dahdi it had to pull in all sorts of linux kernel packages which are nonsensical and probably would fail inside a container.

If it's not required, maybe dahdi should be be moved from depends to recommends in asterisk? That would likely solve the reporter's problem.

Same here. Installing dahdi-linux by hand first worked for me:

apt-get install dahdi-linux

...then install asterisk and it was ok so seems to be something in the order in
which it's installing packages.

It's a different bug, no time to check but also had the following happen:

root@7r6s1:/var/log/asterisk# invoke-rc.d asterisk restart
Stopping Asterisk PBX: asterisk.
Asterisk PBX is already running. Use restart.
root@7r6s1:/var/log/asterisk#

...issuing the command again brought it up OK maybe it needs a sleep(1)
or something.

To fix the missing dahdi module issue, correctly, you will need to install the linux headers for the kernel version installed:

1. uname -r ##to find out the kernel version (e.g., 2.6.31-20-server)
2. sudo apt-get install linux-headers-2.6.31-20-server
3. If you already have the dahdi and asterisk installed, then apt-get should also automatically finish the previous install.

The last comment with the order of installation only gets rid of the error message when installing other programs that have dependencies on the dahdi module. Hope this explanation helps you out!

Just come across this myself. dahdi has a dependency on gawk but it's not in the deps list.

# apt-get install gawk
# hash -r
# apt-get install dahdi-linux

worked for me.

This bug was fixed in the package dahdi-tools - 1:2.2.1-0ubuntu2
