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  package  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.
