[Jaunty, Karmic SRU] openafs-modules-dkms' postinst fails repeatedly when headers missing

[rwun]

Binary package hint: openafs-modules-dkms

IMPACT: If openafs-modules-dkms is installed but the necessary kernel headers to build kernel modules are not, openafs-modules-dkms' postinst will continually fail to complete.

DEVELOPMENT: This bug was fixed in Lucid by syncing in 1.4.11+dfsg-5; for the Jaunty and Karmic SRU, we simply backport the fix synced in from Debian.

PATCH: http://launchpadlibrarian.net/35845647/openafs_1.4.9.dfsg1-0%2Bubuntu3.2.debdiff for Jaunty; http://launchpadlibrarian.net/35845649/openafs_1.4.11%2Bdfsg-1%2Bubuntu0.2.debdiff for Karmic

INSTRUCTIONS: Uninstall linux-headers-`uname -r`, then install openafs-modules-dkms. Observe that openafs-modules-dkms' postinst fails. Observe also that running "dpkg --configure -a" repeatedly does not resolve the problem. Observe also that installing linux-headers-`uname -r` and then running "dpkg --configure -a" still doesn't fix the problem.

REGRESSION: Unlikely. The only changes being made here are to maintainer scripts, and it's backporting a patch from Debian. The likelihood of bizarre toolchain bugs also seems fairly low, given that openafs has had relatively recent SRUs for both Jaunty and Karmic.

I believe this should be fixed in Lucid when 1.4.11+dfsg-5 gets synced in (it's a few days away from hitting Debian testing at the moment).

I'll work on pulling some patches for SRUs together for Jaunty and Karmic

[Evan Broder (broder)]

I believe that the attached patch should fix this issue for Jaunty (as well as the issue Steve reported in bug #368471).

I have a build in my PPA (https://launchpad.net/~broder/+archive/ubuntu-tests), but haven't had a chance to do extensive testing yet.

[Evan Broder (broder)]

And this patch should fix the issue for Karmic.

Same deal - build in the PPA (https://launchpad.net/~broder/+archive/ubuntu-tests), but I haven't tested it yet.

[Evan Broder (broder)]

Let's try writing those patches again, this time with actual LP closers, instead of LP references.

First, Jaunty

[Evan Broder (broder)]

Next, Karmic

[John Dong (jdong)]

The Jaunty and Karmic debdiffs look reasonable to me... ACK from motu-sru.

[Martin Pitt (pitti)]

Accepted openafs into karmic-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

The packages in -proposed fix repeated installation failures for me on both Jaunty and Karmic.

[Launchpad Janitor (janitor)]

This bug was fixed in the package openafs - 1.4.11+dfsg-1+ubuntu0.2

---------------
openafs (1.4.11+dfsg-1+ubuntu0.2) karmic-proposed; urgency=low

  * Backport fix for Debian #553542 to Karmic: (LP: #463429)
    - In the postinst of openafs-modules-dkms, if the openafs module
      is already added in DKMS, try to remove it first before adding
      it. This should more correctly handle the case of a user
      installing this package without the correct kernel headers,
      having it fail in postinst, and then installing the correct
      headers and having dpkg attempt to configure the package again.
      Thanks, Philipp Kaluza. (Closes: #553542)
