[Users] Installation of latest Kernel fails

[Ola Lundqvist]

Hi Kir

The immediate reason is that the Packages file does not match the file size.

Package: linux-image-openvz-amd64
Priority: extra
Section: kernel
Installed-Size: 36
Maintainer: OpenVZ team <devel at openvz.org>
Architecture: amd64
Version: 042+1
Provides: vzkernel
Depends: linux-image-2.6.32-openvz-amd64
Filename:
dists/wheezy/main/binary-amd64/kernel/linux-image-openvz-amd64_042+1_amd64.deb
*Size: 3084*

But if you look at the size of the file it is larger.
ola at debarchiver:/srv/apt-repository/root$ ls -l
dists/wheezy/main/binary-amd64/kernel/linux-image-openvz-amd64_042*
-rw-r--r-- 1 apt-repository apt-repository* 3834* feb 13 20:43
dists/wheezy/main/binary-amd64/kernel/linux-image-openvz-amd64_042+1_amd64.deb

The md5sum does not match either.

The question is why this is the case. dpkg-deb shows a different size, so
the package is really that size.

ola at debarchiver:/srv/apt-repository/root/dists/wheezy/main/binary-amd64$
dpkg-deb -I kernel/linux-image-openvz-amd64*
 new debian package, version 2.0.
 size *3834* bytes: control archive=805 bytes.

When I run the command "dpkg-scanpackages binary-amd64 override" manually
it generates the correct output. However this is not the command used,
instead apt-ftparchive is used. Apt-ftparchive has a cache file that in
certain situations can get corrupt.

The cache file is a good thing as it is possible to scan large archives
quickly, but it can also be corrupt sometimes (if you upload two packages
with the same version number for example). With this cache the indexing
takes a few seconds. Without this cache file the indexing takes ~6 minutes
(when scanning all). I think I have found a good option to apt-ftparchive
(AlwaysStat) to avoid this problem.

I have now removed this cache file and re-generated all the Package files
and now it seems to work. Let me know if you see any further issues.

I'll install a new version of debarchiver with that sets the option for
apt-ftparchive soon.
