# apt-cudf.conf(5)

Configuration file for apt-cudf

## NAME

apt-cudf.conf - Configuration file for apt-cudf

## DESCRIPTION

The configuration file allows one to define default optimization criteria for all solvers known by apt-cudf

## SYNTAX

```
  solver: <solver list> | '*'
```

A comma-separated list of solvers. The character will make the optimization criteria as default for all solvers without a more specific definition.

```
  upgrade: <optimization criteria>
  dist-upgrade: <optimization criteria>
  install: <optimization criteria>
  remove: <optimization criteria>
```

Default optimization criteria associated to apt-get actions. The optimization criteria is solver specific. Specifying a incorrect criteria will result in an error from the  underlying cudf solver. Please refere to the solver man page for the correct syntax

```
  trendy: <optimization criteria>
  paranoid: <optimization criteria>
  <keyword>: <optimization criteria>
```

Define a shortcut for an optimization criteria. The shortcut can then be used by apt-get to pass a specific optimization criteria for a cudf solver

```
  apt-get install gnome --solver aspcud -o "APT::Solver::aspcud::Preferences=trendy"
```

## EXAMPLE

```
  solver: mccs-cbc , mccs-lpsolve
  upgrade: -lex[-new,-removed,-notuptodate]
  dist-upgrade: -lex[-notuptodate,-new]
  install: -lex[-removed,-changed]
  remove: -lex[-removed,-changed]
  trendy: -lex[-removed,-notuptodate,-unsat_recommends,-new]
  paranoid: -lex[-removed,-changed]
  solver: *
  upgrade: -new,-removed,-notuptodate
  dist-upgrade: -notuptodate,-new
  install: -removed,-changed
  remove: -removed,-changed
  trendy: -removed,-notuptodate,-unsat_recommends,-new
  paranoid: -removed,-changed
```
