UPDATE-CUDF-SOLVERS

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 operate 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.
