## set\_download\_mode

Add Apt configuration options to the current configuration to set Apt::Get::Assume-Yes, Apt::Get::Print-URI, Apt::Get::Download-only ready to identify the location of files needing to be downloaded from apt sources.

## get\_cache\_architecture

Reimplemented from dpkg-cross to remove an extra dependency.

## check\_cache\_arch($arch)

Reimplemented from dpkg-cross to remove an extra dependency.

Checks that the supplied `$arch` is (or can be converted to) a DEB\_HOST\_GNU\_TYPE that is known to dpkg-architecture. Sets the module `$arch` variable as a side-effect.

returns the DPKG\_HOST\_GNU\_TYPE or undef

## set\_suite($suite)

Override the &get\_suite default to set a specific repository codename that must be supported by all sources in your sources.list.

## get\_sourceslist ()

Returns the name of the current sources list file.

## use\_mysources ($sources\_file)

Specify that the cache can only use the specified sources.list file instead of collating a complete set of sources from the system apt configuration.

## use\_hostsources

Remove the override and return to the default system sources.

## get\_suite

Logic to identify the current suite from apt-cache policy.

This comes from emdebian-tools - migrate to NorthernCross in due course.

## get\_cache\_apt\_version

Uses dpkg-query to retrieve the version string for the currently installed libcache-apt-perl package. Falls back to a default version if dpkg-query fails.
