Hi,

I was required to upgrade libc6 from lenny to squeeze in order to meet dependencies to install a package from unstable, but the libc6 upgrade failed because libc-bin was not installed. Now dpkg is broken. I tried a manual reinstall of the lenny libc6, as suggested in another thread on this list, but it did not work. The result was:

debian:/home/chris# dpkg -i libc6_2.7-18lenny2_i386.deb
dpkg: `ldconfig' not found on PATH.
dpkg: 1 expected program(s) not found on PATH.
NB: root's PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin.

How can this be fixed? And shouldn't there be a big warning that trying to upgrade libc6 can break dpkg, on the Debian website page for libc6?

Best regards,
Chris Austin.

What should really be the "big warning" is mixing releases... I don't see
this as possible however. How is dpkg to know that the libc6 upgrade is not
for security patches or point release? I suppose something could be put in
place so that the security repo is treated differently.

The best way to avoid this: Don't mix releases. When necessary, its
generally safer to build the source packages. You will also realize how far
you are digging into testing when you start needing to backport libs.

This is potentially reversible, but you should know in the future that core
packages such as libc6, perl, python, and etc should never be mixed between
releases.

I have no advice for fixing the current issue... Only avoiding it in the
future.

How could this happen, given that libc6 depends on libc-bin?

Use the "--force-bad-path" option, see "dpkg --force-help".

There is, actually this holds for any package:

,----[ http://packages.debian.org/en/squeeze/i386/libc6/download ]
| If you are running Debian, it is strongly suggested to use a package
| manager like aptitude or synaptic to download and install packages,
| instead of doing so manually via this website.
`----

Follow this advice and do not use dpkg directly if you don't know what
you're doing. Especially not for required packages.

Bah! WFM.

That said, I definitely think twice about any proposal from apt(itude) that
includes updating the system C or Perl runtime. I don't like having to
recover from a broken apt (or worse dpkg) -- but that hasn't happened since I
moved to Debian full time.

(Pro Tip: A .deb is an "ar" archive.)
