Bug Description

SRU Justification:

Impact: As the conflict statement can be generated incorrectly it is possibly to accidentally install both packages.

Fix: Change to build system to exclude both cases as they never could happen together anyway.

---

installing both packages results in:

dpkg: error processing /var/cache/apt/archives/linux-image-2.6.31-14-virtual_2.6.31-14.48_amd64.deb (--unpack):
 trying to overwrite '/boot/vmlinuz-2.6.31-14-server', which is also in package linux-image-2.6.31-14-server 0:2.6.31-14.48

In jaunty, the 2.6.28-virtual kernel had the following conflicts:

Conflicts: hotplug (<< 0.0.20040105-1), linux-image-2.6.28-15-server

but in karmic it's changed to:

Conflicts: hotplug (<< 0.0.20040105-1), linux-image-2.6.31-14-generic-pae

I guess I see that this _is_ a problem, but _why_ would you do this?

Steve Beattie (sbeattie) wrote :

For example, if someone installs from the ubuntu-server image but forgets to select (or doesn't know about) the minimal virtual machine option in the F4 boot menu, and then post install tries to convert over to using the -virtual kernel (this actually happened to me with a jaunty install, which is how I knew about the conflict that was present in that release's packages).

What I can't figure out is why the conflict isn't getting set to server; http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-karmic.git;a=blob;f=debian.master/sub-flavours/virtual.vars already contains:

   8 darch="`dpkg-architecture -qDEB_HOST_ARCH`"
   9 if [ "$darch" = "i386" ]
  10 then
  11 based_on="generic-pae"
  12 else
  13 based_on="server"
  14 fi
  15 # The provides and conflicts are REQUIRED
  16 provides="redhat-cluster-modules"
  17 conflicts="linux-image-PKGVER-ABINUM-${based_on}"

which ought to set the conflicts to server when the amd64 kernels are built, but as evidenced by the published packages, doesn't actually do so.

Why does there have to be a conflict anyway? If the kernel in the virtual flavor was named vmlinuz-2.6.x-y-virtual, the packages could coexist.

Tessa (unit3) wrote :

Definitely agree with bse4711, this shouldn't even be a conflict. linux-image-virtual packages should have kernels and modules with a -virtual extension, not a -server one.

And just to agree to Steve's content, I ran into this after upgrading a VPS to karmic, which installed the upgraded -server kernel, and then wanting to move to the -virtual kernel. I don't have control over the install with my VPS host, so that seemed like the easiest way to get where I needed to be... only then I was foiled by this bug. ;)

I've reproduced the lacking conflict with the latest server and virtual kernels in karmic-updates, 2.6.31-20.58, and can confirm that the kernels in karmic-proposed, linux-image-2.6.31-21-{server,virtual} 2.6.31-21.59, correctly conflict on amd64. I also verified that the linux-image-2.6.31-21-{generic-pae,virtual} kernel packages continue to conflict with each other.

I also verified that none of the 2.6.31-20.58 kernels (generic, server, generic-pae for {i386,amd64}) introduce no regressions in the qa-regression-testing kernel tests. Marking verification-done.

The reason these packages need to conflict is that the linux virtual kernel is not separately built from the server/generic-pae kernel images. The same kernel image is used as both, it's just that the virtual kernel packages include fewer kernel modules. Re- architecting the kernel build process is out of scope for a karmic SRU as well as for lucid, given how late it is in its development cycle.

I came across this bug as I was going to report a bug that the -server and -virtual kernels conflict in lucid. I can see that this conflict is still necessary as of 2.6.32-33:

http://packages.ubuntu.com/lucid-updates/amd64/linux-image-2.6.32-33-virtual/filelist

I have noted that this was fixed in later releases (maverick, natty). So maybe that will help anyone who comes across this bug report down the road as I did.
