update-cudf-solvers(8)

NAME

   update-cudf-solvers - register available CUDF solvers as APT external
   solvers

SYNOPSIS

   update-cudf-solvers [OPTION]...
   update-cudf-solvers [OPTION]... --remove
   update-cudf-solvers [OPTION]... --list

DESCRIPTION

   update-cudf-solvers maintain the list of installed CUDF solvers and
   register them as external solvers for APT.

   The first form (without mandatory options) should be invoked each time
   a new CUDF solver specification file is added to or removed from the
   CUDF solver specification directory (by default
   /usr/share/cudf/solvers).  update-cudf-solvers will synchronize the
   differences with APT external solvers, by installing suitable symlinks
   to the /usr/bin/apt-cudf wrapper under /usr/lib/apt/solvers.

   The second form (with the mandatory "--remove" option) will remove all
   installed external APT solvers that originated from CUDF solvers. It's
   a cleanup operation meant to be used only upon removal of the apt-cudf
   package.

   The third form just lists available solvers and exit.

   Note that other, non-CUDF based, APT external solvers might be present
   under /usr/lib/apt/solvers. update-cudf-solvers leaves the untouched
   and act only on (present or past) APT solvers corresponding to CUDF
   solvers.

TRIGGER-BASED OPERATION

   The directory /usr/share/cudf/solvers is monitored by a dpkg trigger
   that invokes update-cudf-solvers as needed. In all but exceptional
   circumstances, you should not be required to opearte update-cudf-
   solvers manually.

OPTIONS

   -d
   --debug
       Print debugging information during operation.

   -h
   --help
       Show usage information and exit.

   -l
   --list
       List available solvers and exit. Both CUDF and APT's external
       solvers (AKA "EDSP solvers") will be listed.

   -r
   --remove
       Unregister all CUDF solvers.
