Subject: linux-2.6: Hangs while attempting to purge

Package: linux-2.6
Severity: serious
Justification: Won't uninstall cleanly

It hangs on this line of the postrm script:

my $ret = purge();

I can get it to work by deleting this line. Perhaps this is because a
debconf routine is being called after "stop" has been called? I don't know,
but anyway it's a serious bug.

This bug appears in linux-image-2.6.14-2-686 and linux-image-2.6.15-1-686,
and I assume in other flavours as well.

Hi Nathanael.
I can confirm this problem, in fact i have also filed a bug against it:
see #344767.

Hi both of you, ...

It would be great if you could confirm the exact version of those two
packages, and could provide us some log of what is happening, as this bug
report doesn't seem to be very informative.

This issue should have been fixed in linux-image-2.6.15-1-686 though, so we
really need to find out what did go wrong.

Also, could you please give us the output of ls -lR /etc/kernel, and append it
to the bug report ?

Friendly,

Sven Luther

For me, i have provided information in bug #344767, as i explained in
the previous message: versions, logs, ecc.

I haven't tested 2.6.15 because it isn't available in my mirror yet. But
the Nathanael posts tell us that the problem is still present in the
latest kernel.
As soon as it will be available on the mirror i use, i'll test 2.6.15.

Do you mean this?
$ ls -lR /etc/kernel-*
-rw-r--r-- 1 root root 179 2005-09-11 20:55 /etc/kernel-img.conf
-rw-r--r-- 1 root root 1006 2005-11-08 00:35 /etc/kernel-pkg.conf

Ok, 2.6.15 is arrived.
I've tryed to install linux-image-2.6.15-1-486 (version 2.6.15-1), then
to purge it and the operation failed. But now, it doesn't hang as stated
in the bug reports, but fails with an error:

But since the "486" flavour is a new entry, i've also tryed
linux-image-2.6.15-1-686-smp, which i know was failing during purge
(while i was investigating for bug #344767, i had also tested
linux-image-2.6.14-2-686-smp (2.6.14-6), and it hanged like the others):
the purge operation for 2.6.15-686-smp failed like 486 flavour:

Indeed, this is a grub RC bug, which need to fix their grub-update call from
/etc/kernel/*.d/grub or whatever scripts.

Ah, looking at this one now.

But it should not, which is why it is important to investigate. 2.6.14-2 is no
more in the archive as of today, and thus no longer relevant.

For information, i had this problem on powerpc, where the debconfified
mkvmlinuz package used debconf script in the /etc/kernel way described below,
but we fixed it last week, and the new 2.6.15-1 kernel build depend on at
least the 10.028 or 10.029 kernel-package version with this fixed.

So, either it is a new problem, or somehow the version Nathanael has built was
done so using an older kernel-package which was buggy.

No, the kernel-packahe generated postinst and co script have support for
script hooks, found under /etc/kernel/postinst.d/ and co, i want to know what
exactly you have there, because it is probable that some random third party
hook (like grub-update call maybe) causes this problem.

I have now looked at this bug report, and it is indeed probable that it is a
bug in grub, who wants to write to stdout, which plays hell with the new
kernel-package debconfified due to messing up the debconf protocol.

Since policy mandates debconf for interaction, this is a RC grub bug, and a
proposed fix is have grub-updates output info on stderr instead.

There were some bugs we redirected to the grub guys, but i can't find them in
the BTS anymore, so reasigning the 344767 bug report to them.

Ok, i have also read the other your mails regards the grub bug.
But i would inform you that the /etc/kernel/ folder (that you have
requested us to post in the previous messages) doesn't exist on my system...

Mmm, then i am out of my depth, and i think it is best you follow up with
Manoj, since it is a kernel-package issue.

I retested this (a tedious process to say the least) and 2.6.15-1 appears to
purge cleanly now. I'm using lilo, so I haven't tested it with hook scripts
present. Closing this.

If you're using lilo, how are your tests relevant to a bug filed on grub?
