Subject: dpkg-shlibdeps: error: is not a valid version

Date: Sun, 12 Oct 2014 14:05:47 +0200

Package: dpkg-dev
Version: 1.17.17
Severity: serious
File: /usr/bin/dpkg-shlibdeps
User: helmutg@debian.org
Usertags: rebootstrap

Hi Guillem,

I am not yet certain that this is a bug in dpkg, but I am filing it
prematurely due to the severity of the breakage observed. jenkins.d.n
did run into the dinstall adding dpkg 1.17.17. Almost immediately after
that, packages started to FTCBFS at various points with the error
message:

| dpkg-shlibdeps: error:  is not a valid version

The bad news is that this might mean dpkg is producing broken symbols
files.

Example instances:

https://jenkins.debian.net/job/rebootstrap_arm64_gcc49/93/console
https://jenkins.debian.net/job/rebootstrap_powerpc_gcc49_nobiarch/79/console
https://jenkins.debian.net/job/rebootstrap_mips_gcc49_nobiarch/75/console

It definitely is connected to that dinstall (by timing), but the
likelyhood that dpkg is involved is high.

I'm sorry for not providing more details at this point.

Helmut

I think I might know what's going on, checking now offlist.

commit 8f0122e0c439de1ee4521a9009427aa3704de521
Author: Guillem Jover <guillem@debian.org>
Date:   Sun Oct 12 15:16:41 2014 +0200

    dpkg-shlibdeps: Handle empty minimum versions when initializing them
    
    If the minimum version is empty (which means it was 0), we cannot use it
    to compare against the existing minimum version if that exists, and we
    should not be overwritting that, either.
    
    Regression introduced in commit 51c55641fb6c66e149ea93c344cb788c68978c75.
    
    Closes: #764929
