NAME

       which-pkg-broke - find which package might have broken another

SYNOPSIS

       which-pkg-broke package

DESCRIPTION

       The  which-pkg-broke  program  will retrieve a list of the named package and all its dependencies sorted by the time they were installed on
       the system (as determined from the mtime information of /var/lib/dpkg/info/*.list .

       This tool makes it possible for a system admin to obtain information that might correlate installation of package dependencies with a pack-
       age breakage in order to find which package update might be responsible for the breakage.

EXAMPLES

       This tool can be useful determine which package dependencies were upgraded more recently and might be associated with the bug that is being
       observed.  For example, if aptitude stops working properly, an administrator can run:

       $ which-pkg-broke aptitude
       Package <libapt-pkg-libc6.3-5-3.3> has no install time info
       libdb1-compat			Fri Aug  8 03:02:11 2003
       libsigc++-1.2-5c102		Fri Aug  8 05:15:58 2003
       aptitude 			Sun Jan 11 17:38:06 2004
       libncurses5			Sun Jan 18 08:11:05 2004
       libc6				Thu Jan 22 07:55:10 2004
       libgcc1				Tue Jan 27 07:37:22 2004
       gcc-3.3-base			Tue Jan 27 07:37:31 2004
       libstdc++5			Tue Jan 27 07:37:32 2004

       So depending on exactly when the misbehaviour started, there may be a reason to point the finger at a more-recently  updated  library  like
       libstdc++ or libncurses, which are more-recently installed than aptitude itself.
