apt-cudf-get [arguments]


apt-cudf-get is a wrapper that allows one to invoke apt-get with external solvers while ignoring apt's pinning.

All options are passed on to apt-get.

Normally, apt uses so-called pinning to select a candidate version of a package in case there are several versions available. This also holds when calling apt-get with external solvers. However, when it is not possible to find a solution under this constraint, it may be useful to relax pinning and to allow the external solver to choose among all available versions of packages in order to satisfy dependencies, not only those that are selected by the pinning. This is precisely what apt-cudf-get does.

Note that, when using an external solver, the proposed solution may contain any available version of the packages that are given as arguments to install on the command line without specifying a version qualifier.

For example

    apt-cudf-get --solver aspcud install ocaml

may propose to install any available version of ocaml, while

    apt-cudf-get --solver aspcud install ocaml=4.01.0

will only propose to install ocaml in version 4.01.0

Not all types of arguments to apt are correctly treated by this wrapper, in particular not the +pkg and -pkg shorthands for installation and removal requests.
