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.

APT-MARK(8) APT APT-MARK(8)NAME
apt-mark - show, set and unset various settings for a package
SYNOPSIS
apt-mark {-f=filename | {auto | manual} pkg... | {showauto | showmanual} [pkg...] } | {-v | --version} | {-h | --help}
apt-mark {hold | unhold | install | remove | purge} pkg... | {showhold | showinstall | showremove | showpurge} [pkg...]
DESCRIPTION
apt-mark can be used as a unified front-end to set various settings for a package, such as marking a package as being
automatically/manually installed or changing dpkg selections such as hold, install, deinstall and purge which are respected e.g. by apt-get
dselect-upgrade or aptitude.
AUTOMATICALLY AND MANUALLY INSTALLED PACKAGES
When you request that a package is installed, and as a result other packages are installed to satisfy its dependencies, the dependencies
are marked as being automatically installed, while the package you installed explicitly is marked as manually installed. Once an
automatically installed package is no longer depended on by any manually installed package it is considered no longer needed and e.g.
apt-get or aptitude will at least suggest removing them.
auto
auto is used to mark a package as being automatically installed, which will cause the package to be removed when no more manually
installed packages depend on this package.
manual
manual is used to mark a package as being manually installed, which will prevent the package from being automatically removed if no
other packages depend on it.
showauto
showauto is used to print a list of automatically installed packages with each package on a new line. All automatically installed
packages will be listed if no package is given. If packages are given only those which are automatically installed will be shown.
showmanual
showmanual can be used in the same way as showauto except that it will print a list of manually installed packages instead.
Options
-f=filename, --file=filename
Read/Write package stats from the filename given with the parameter filename instead of from the default location, which is
extended_status in the directory defined by the Configuration Item: Dir::State.
PREVENT CHANGES FOR A PACKAGE
hold
hold is used to mark a package as held back, which will prevent the package from being automatically installed, upgraded or removed.
unhold
unhold is used to cancel a previously set hold on a package to allow all actions again.
showhold
showhold is used to print a list of packages on hold in the same way as for the other show commands.
SCHEDULE PACKAGES FOR INSTALL, REMOVE AND PURGE
Some front-ends like apt-get dselect-upgrade can be used to apply previously scheduled changes to the install state of packages. Such
changes can be scheduled with the install, remove (also known as deinstall) and purge commands. Packages with a specific selection can be
displayed with showinstall, showremove and showpurge respectively. More information about these so called dpkg selections can be found in
dpkg(1).
OPTIONS -h, --help
Show a short usage summary.
-v, --version
Show the program version.
-c, --config-file
Configuration File; Specify a configuration file to use. The program will read the default configuration file and then this
configuration file. If configuration settings need to be set before the default configuration files are parsed specify a file with the
APT_CONFIG environment variable. See apt.conf(5) for syntax information.
-o, --option
Set a Configuration Option; This will set an arbitrary configuration option. The syntax is -o Foo::Bar=bar. -o and --option can be
used multiple times to set different options.
FILES
/var/lib/apt/extended_states
Status list of auto-installed packages. Configuration Item: Dir::State::extended_states.

apt-mark returns zero on normal operation, non-zero on error.
