# dpkg -l apt
...
ii apt 0.7.3 Advanced front-end for dpkg
Source-compiled apt 0.7.4 has identical results (I can't test the binary
package, because it requires me to fix the same situation in order to
test it)
The failure is apparently in the Conflicts logic:
new zlib1g depends on new libc6 2.6-2 (WHY?!?)
libc6-dev must be a matching version, so goes to 2.6-2
libc6-dev 2.6-2 depends on linux-libc-dev
linux-libc-dev conflicts with linux-kernel-headers
... CURRENT libc6-dev depends on linux-kernel-headers, so it's being
marked as removed. The gigantic purge listed above comes directly
from the loss of libc6-dev.
Now, I can't see any way this isn't a bug. The only reason libc6-dev is
being removed is because it's being upgraded, and because it's being
upgraded, it has to install a package that conflicts with a package the
OLD version Depends on, so it must be removed. "apt-cache rdepends"
shows nothing else on my system requires linux-kernel-headers or
linux-libc-dev (libkxl0-dev is the only other package that requires it,
and it's not installed)
I can't speak to the situation in the first two reporters, but I'm
willing to bet it's a similar failure.
I also took a snapshot of the system at the time, so someone can test
it. (amd64 chroot, ~30mb tarball of what's needed to reproduce + my
skeleton chroot)
