build-debirf-kernel fails on testing ("lenny")

[jrollins]

build-debirf-kernel fails when run on lenny:

servo:1:~/src> build-debirf-kernel 
No packages found matching linux-source-2.6.18.
Not continuing until you have the right packages installed.
servo:1:~/src>

i'm not sure exactly what's going on, but it appears that linux-source-2.6.18 actually pulls a different version:

servo:0:~/src> apt-get source linux-source-2.6.18
Reading package lists... Done
Building dependency tree... Done
Skipping already downloaded file 'linux-2.6_2.6.20-1.dsc'
Skipping already downloaded file 'linux-2.6_2.6.20.orig.tar.gz'
Skipping already downloaded file 'linux-2.6_2.6.20-1.diff.gz'
Need to get 0B of source archives.
Skipping unpack of already unpacked source in linux-2.6-2.6.20
servo:0:~/src> 

i don't understand this. anyway, build-debirf-kernel is failing. where does it look for the kernel source package?

[dkg]

build-debirf-kernel tries to build a kernel to match the one you're running.

If you've switched to lenny, but haven't rebooted into the lenny kernel, it won't be able to find sources for the running kernel.

[dkg]

hrm looks like 2.6.20 isn't actually in lenny yet. what's in yer /etc/apt/sources.list?

[jrollins]

there are lots of things in my sources.list, including some unstable sources, but more to the point:

servo:0:~> apt-cache policy linux-source-2.6.18
linux-source-2.6.18:
  Installed: (none)
  Candidate: 2.6.18.dfsg.1-12
  Version table:
     2.6.18.dfsg.1-12 0
        700 http://debian.lcs.mit.edu testing/main Packages
        600 http://debian.lcs.mit.edu unstable/main Packages
servo:0:~> 

[dkg]

Sorry. I should have figured this out much sooner.

You simply needed to do (as the superuser):

apt-get install linux-source-2.6.18

The initial error message:

No packages found matching linux-source-2.6.18.
Not continuing until you have the right packages installed.

should probably be amended to say "no packages found on the local system matching..."

[dkg]

Actually, that error message appears to be emitted by dpkg -l itself, so i can't amend the error report easily.
