apt.debfile — Classes related to debian package files

The apt.debfile provides classes to work with locally available debian packages, or source packages.

Binary packages

class apt.debfile.DebPackage(filename=None, cache=None)

A Debian Package (.deb file).

The DebPackage class is a class for working with ‘.deb’ files, also known as Debian packages.

It provides methods and attributes to get a list of the files in the package, to install the package and much more.

If you specify cache it has to point to an apt.cache.Cache() object.

Changed in version 0.7.9: Introduce all new methods (everything except for open() and filelist)

check()
Check if the package is installable.
check_breaks_existing_packages()
check if installing the package would break exsisting package on the system, e.g. system has: smc depends on smc-data (= 1.4) and user tries to installs smc-data 1.6
check_conflicts()

Check if there are conflicts with existing or selected packages.

Check if the package conflicts with a existing or to be installed package. Return True if the pkg is OK.

compare_to_version_in_cache(use_installed=True)

Compare the package to the version available in the cache.

Checks if the package is already installed or availabe in the cache and if so in what version, returns one of (VERSION_NONE, VERSION_OUTDATED, VERSION_SAME, VERSION_NEWER).

conflicts

data_content(name)
return the content of a specific control.tar.gz file
depends

filelist
return the list of files in the deb.
install(install_progress=None)

missing_deps

open(filename)
open given debfile
provides
List of virtual packages which are provided by this package.
replaces

replaces_real_pkg(pkgname, oper, ver)

Return True if a given non-virtual package is replaced.

Return True if the deb packages replaces a real (not virtual) packages named (pkgname, oper, ver).

required_changes
